INFO@RNSACOUSTICS.COM RE: Floor-Ceiling Acoustical Test Report and Recommendations Ogden Residence, 2741 Monroe Street, Carlsbad, California RECEIVED MAR 2 6 2021 CITY OF CARLSBAD BUILDING DIVISION The following report summarizes the results of our acoustical testing of your floor-ceil,:.. I ~d Dear Chad and Rebecca: Y]Jv subsequent recommendations. V1 Jlf ni Project Summary The owner is planning to convert the basement of their single-family home into an Accessory Dwelling Unit (ADU). The basement is separated from the first floor of the home by an existing floor-ceiling assembly. As part of the architectural plans and permitting process, the City of Carlsbad is requiring that the design meets minimum requirements for acoustical separation. RNS Acoustics was engaged to conduct acoustical testing to determine the field ASTC and AIIC performance of the floor-ceiling assembly, and provide recommendations, if necessary, to improve performance. On January 22, 2021, we conducted ASTC and AIIC testing of the floor-ceiling separating the Main Floor Living Room from the Basement Front Room. The Basement Front Room has two areas with different ceiling heights. The initial drawings we reviewed indicated the floor-ceiling is a simple single joist system (floor, subfloor, joist, ceiling). However, based on our observations and subsequent investigations by the architect, it was determined that the areas with the lower ceiling are actually a double joist system (floor, subfloor, joist, airspace, studs, ceiling). The double joist system would be expected to perform notably better than the single joist system. The ASTC and AIIC results for this area were determined to be below code minimum requirements. On February 12, 2021, we conducted ASTC and AIIC testing of the double joist floor-ceiling separating the Main Floor Family Room and Kitchen from the Basement Bedroom and Bathroom. As expected, the ASTC and AIIC results for these areas were notably better and found to meet or exceed the code minimum requirements. We recommend renovating the ceiling in the Basement Front room to improve the ASTC and AIIC performance. Ogden Residence STC IIC Report RNS Acoustics 2021/02/24 This Page Alone is Not a Complete Report Page 1 of 42 C~-xJUJ-2/foO Test Results The following tables summarize the results of our impact (AIIC) and airborne (ASTC) acoustical testing.

Walls and floors separating units shall have a sound transmission class (STC) of not less than 50. Additionally, floors must have an impact insulation class (IIC) rating of not less than 50. CBC Section 1207. Show the location of and provide details of the listed wall and floor/celling assemblies and Indicate the listing agency and listing number for the tested ratings. Note that STC and IIC ratings are "design ratings" which are based on a laboratory test. Industry standard practice (CBC/ IBC / UBC) is to give a 5 point allowance when an assembly is field tested. Further inspection of the "City of Carlsbad Noise Guidelines" and the referenced California Building Code (CBC Section 1207) indicates that assemblies may also be field tested to determine compliance with the minimum required acoustical performance. The following segments are excerpted from the "City of Carlsbad Noise Guidelines" document (2013, pages A-4 and A-5), which are in turn appear to be excerpted from the California Code of Regulations (Title 24, Part 2, Chapter 12): 1207.7 Airborne sound insulation. All such acoustically roted separating wall and flocr-ceding assemblies shall provide airborne sound insulation equal ta that required to meet a sound transmission class (STC) rating of 50 based an laboratory tests as defined in ASTM f 90 and E 413. Field-tested assemblies shall meet a noise isolation class (NIC} rating of 45 for occupied units and a normalized noise isolation class (NIN/CJ rating of 45 for unoccupied units as defined in ASTM f 336 and f 413. Ogden Residence STC IIC Report RNS Acoustics 2021/02/24 This Page Alone is Not a Complete Report Page 2 of 42 1207.8 Impact sound Insulation. All ocoustico/ly roted separating floor-ceiling assemblies shall provide impact sound insulation equal to that required to meet a IIC rating of 50 based on laboratory tests as defined in ASTM E 492 and E 989. Field-tested assemblies shall meet o field impact insulation class (FIIC} roting of 45 for both occupied and unoccupied units as defined in ASTM E 1007 and E 989, with the exception that the measured impact sound pressure levels shall not be normalized to a standard amount of absorption in the receiving room. Note that NIC and NNIC ratings are similar to a field tested ASTC rating. Also note that FIIC is equivalent to a field t ested AIIC rating. The "FIIC" designation was replaced with "AIIC" in previous versions of the relevant ASTM standards, but the test method and resulting rating are equivalent. Finally, the most current version of the California Building Code (2016) appears to have modified these requirements slightly, as follows: 1207.2 Air-Borne Sound We1ll"-. partitions and floor/ce1hng assemblies separating lwel ,, " ir • and ,;te .. r 1 .~ l n t<. from each other or from pubhc or servJCe areas shall have a sound transmission class of not less than 50, or not less than 45 ,f field tested. for air-borne noise when tested in accordance with ASTM E90. Penetrations or openings m construction assemblies for piping; electrical devices: recessed cabinets: bathtubs: soffits: or heating. ventilating or exhaust ducts shall be sealed. lined. insulated or otherwise treated to maintam the required ratings. This requirement shall not apply to e'l•, J i:> doors: however. such doors shall be tight f1ttmg to the frame and slll. 1207.3 Structure-Borne Sound Floor/ceiling assemblies between ; e n u 1t and sl ,pl' 10 n _ or between a .-.e· 1'1.., 1 c or ee1 1 1c ur and a pubhc or service area within the structure shall have an impact insulation class rating of not less than so. or not less than 45 1f field tested. when tested in accordance with ASTM E492. Exception: Impact sound insulat,on is not required for floor-ce1/mg ossemb/Jes over nonhab1cable rooms or 1 1 noc designed to be occupied, such as garages, mechamcal rooms or storage areas. Significance The Main Floor living Room to Basement Front Room tested below the minimum requirements, due to the single joist floor-ceiling assembly. The double joist floor-ceiling areas were found to meet or exceed the code minimum requirements for acoustical performance, as shown by the tests from the Main Floor Kitchen and Family Room to the Basement Bedroom and Bathroom.

We recommend that no renovations should be necessary for the Bedroom and Bathroom, based on the field-tested ASTC and AIIC results being above 4S. 2. We recommend renovating the Basement Front Room to improve the acoustical performance of the floor-ceiling. a. The existing ceiling should be removed. b. New 2x4 or 2x6 framing should be added below the existing floor joists. The new framing should be supported from the walls and have no connection to the existing floor joists above. c. Insulation should be added to fill the entire ceiling cavity. Sound attenuating fiberglass baits or mineral wool would be acceptable. d. Minimum two layers of 5/8" thick Type X or Type C gypsum board should be added to the new framing. The seams of the second layer should be staggered with respect to the seams of the first layer. The perimeter of the ceiling should be held back 1/8" from the walls and the gap filled completely with acoustical caulking. It is our professional opinion that this renovated assembly will perform above the field tested ASTC 45 and AIIC 45 code minimum requirements. The field tests that we conducted in the Bedroom and Bathroom with the double joist system passed code minimum requirements. The new assembly in the Front Room will be constructed similarly to the existing double joist assembly in the Bedroom and Bathroom, but with an additional layer of gypsum board, which will provide an additional 2·3 point improvement. Also, for the ASTC 46 result in the Bedroom, we observed some flanking paths (weak link) where sound was coming from the crawlspace door, wall adjacent the crawlspace, and access panel in the ceiling. We expect that the renovated front room will perform better than this since the construction quality can be improved, and the crawlspace door and access panel conditions do not exist. For further corroboration that the renovated assembly will meet code minimum requirements, consider the following comparisons with test reports found for similar assemblies: • A lab test report from Kinetics Noise Control for a similar assembly achieved STC 59 and IIC 52. This assembly consisted of wood flooring, no underlayment, no gypcrete topping slab, 2x10 floor joists, 3-1/2" fiberglass batts, Model ICW spring hangers, and two layers of gypsum board. • Also, a field test report from Kinetics Noise Control for a similar assembly achieved NIC 49 and FIIC 51. This assembly consisted of wood flooring, no underlayment, no gypcrete topping slab, 3x14 joists between lS"xlS" beams, 3·1/211 fiberglass batts, Model ICW spring hangers, and two layers of gypsum board. • Assemblies with spring isolation hangers typically perform very well because the springs effectively decouple the ceiling system from the floor structure. In the recommended renovated assembly, the ceiling will be decoupled from the floor structure, since the new joists will by framed out from the walls and will not be attached to the existing floor joists. Also, we recommend filling the entire cavity with fiberglass bait insulation, which will further help to improve the STC and IIC performance. Ogden Residence STC UC Report RNS Acoustics 2021/02/24 This Page Alone is Not a Complete Report Page 6 of 42 Test M ethodology ASTC was measured by using a loudspeaker and pink noise generator located in the Source Room. The average sound levels in the Source room and Receive room were measured using the scanning method for a minimum of 30 seconds each. Finally, the reverberation time (RT60) was measured in the Receive Room. The partition area and room volume of the Receive room were calculated based on the architectural drawings. AIIC testing utilizes a calibrated tapping machine located in the Source Room. The tapping machine rotates a cam shaft that repeatedly lifts and drops hammers on the floor. The tapping machine is placed at four different orientations on the floor. The resulting impact sound levels are then measured in the Receive Room. Finally, the reverberation time (RT60) was measured in the Receive Room. The partition area and room volume of the Receive Room were calculated based on the architectural drawings.

Ogden Residence STC IIC Report RNS Acoustics 2021/02/24 This Page Alone is Not a Complete Report Page 15 of 42 Appendix B -Terminology The following are simplified descriptions of the terminology and acronyms used in the preceding reports. We would be happy to discuss these or other technical acoustical terms in more detail at your direction. Airborne Sound Isolation STC -Sound Transmission Class -A single number rating that indicates how well a building element blocks airborne sound at mid-frequencies associated with speech. STC is a tested in an NVLAP accredited laboratory according to the ASTM E90 standard, and calculated in accordance with ASTM E413. ASTC -Apparent Sound Transmission Class -ASTC is a field tested STC rating. ASTC tests the as-built performance of a building element according to the ASTM E336 standard. Industry standards and codes typically provide a 5-point allowance when comparing field tested ASTC performance to lab tested STC ratings. For example, if an assembly is lab tested with an STC 50, we would expect the same assembly constructed in an actual building would field test at ASTC 45 or higher. FSTC -Field Sound Transmission Class -FSTC is a deprecated acronym that has been superseded by ASTC. FSTC may be found in older versions of the relevant ASTM standards and certain Building Codes and regulations. ASTC ratings are equivalent to an FSTC rating. Impact Sound Isolation IIC -Impact Insulation Class -A single number rating that indicates how well a floor-ceiling assembly blocks impact noise from a space below. STC is a tested in an NVLAP accredited laboratory according to the ASTM E492 standard, and calculated in accordance with ASTM E989. AIIC-Apparent Impact Insulation Class-Al IC is a field tested IIC rating. AIIC tests the as-built performance of a floor-ceiling assembly according to the ASTM E1007 standard. Industry standards and codes typically provide a 5-point allowance when comparing field tested AIIC performance to lab tested IIC ratings. For example, if an assembly is lab tested with an IIC 50, we would expect the same assembly constructed in an actual building would field test at AIIC 45 or higher. FIIC -Field Impact Insulation Class -FIIC is a deprecated acronym that has been superseded by AIIC. FIIC may be found in older versions of the relevant ASTM standards and certain Building Codes and regulations. AIIC ratings are equivalent to an FIIC rating.

Please note that this floor assembly was tested as one of seven specimens under contract A 1041 in 1994, but an individual report for this specimen was not requested or issued as part of that contract For report purposes, the floor is identified as Floor "G", as designated in the original report A-1041.1. Construction on the series of floor assemblies for contract A1041 started 4 April 1994 and concluded 22 May 1994. The airborne and impact sound transmission loss tests for this floor assembly were performed on 19 May 1994. Floor "G" Each floor had a wood joist frame, with the gypsum board ceiling hung on an ICW hanger system. The hanger system, provided by the client, comprised fourteen ICW-50 hanger brackets, six ICW-100 hanger brackets (1 kg each), 16 gauge steel rails (0.7 kg/m) which ran parallel to the joists and 22 gauge steel furring channels (0.4 kg/m). The ICW hanger brackets were on 1.2 m centers. Details of the floor topping, and other elements of the construction are given in Table 1. The area of the specimen was 20.0 m2; however the exposed specimen area was 17.85 m2• The weights of the materials are given for the entire floor area. The exposed specimen area was used for the calculations of transmission loss. -Page 1 of 11- This Page Alone is Not a Complete Report Page 20 of 42 --------· FACILITIES AND EQUIPMENT B3463.15 Ogden Residence STC UC Report RNS Acoustics 2021102/24 Table 1: Floor "G" comprised the following elements, listed from top to bottom: Surface Weight weight (kg/m2) (kg) 8 mm parquet flooring 5.4 108.0 16 mm plywood 7.1 142.0 240 mm wood joists, 400 mm o.c. 281.7 (3.7 kg/m) 90 mm R12 glass fibre batts 1.0 19.6 27 mm ICW hangers 74.3 16 mm fire rated gypsum board 10.2 203.5 16 mm fire rated gypsum board 10.1 201.0 TOTAL 33.7 1030.1 Total thickness: 323mm The test specimen was mounted in the IRC acoustical floor test opening which measures 4.70 m x 3.78 m. The area used for the calculations of impact transmission and airborne sound transmission loss was 17.85 m2• The acoustics floor test facility comprises two reverberation rooms with a moveable test frame between the two rooms. Both rooms have a volume of 175 m3. Measurements were controlled by a desktop PC-type computer interfaced to a Norwegian Electronics type 830 real time analyser. Each room had a calibrated Brue! & Kjaer condenser microphone with a type 4166 cartridge that was moved under computer control to nine positions used for the acoustical measurements. Each room had four loudspeakers driven by separate amplifiers and independent noise sources. To increase the randomness of the sound field, there were also fixed diffusing panels in each room. -Page 2 of 11- This Page Alone is Not a Complete Report Page 21 of 42 TEST PROCEDURE B3463.15 Ogden Residence STC IIC Report RNS Acoustics 2021/02/24 Airborne Sound Transmission Loss Airborne sound transmission measurements were conducted in accordance with the requirements of ASTM E90-90, "Standard Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions", and of ISO 140-3 1978, "Laboratory Measurement of Airborne Sound Insulation of Building Elements". The Sound Transmission Class (STC) was determined in accordance with ASTM E413-87, "Classification for Rating Sound Insulation". The Weighted Sound Reduction Index (Rw) was determined in accordance with the current version of ISO 717-1, "Rating of Sound Insulation in Buildings and of Building Elements, Part 1: Airborne Sound Insulation". One-third octave band sound pressure levels were measured for 30 seconds at each microphone position in each room and then averaged to get the average sound pressure level in the room. Five sound decays were averaged to get the reverberation time at each microphone position in the receiving room. These times were averaged to get the average reverberation times for the room. The average sound pressure levels of both the source and receiving rooms and the average reverberation times of the receiving room were used to calculate sound transmission loss values. Airborne sound transmission loss tests were performed in the forward (receiving room is the lower room) and reverse (receiving room is the upper room) directions. Results presented in this report are the average of the tests in these two directions. A complete description of the test procedure, information on the flanking limit of the facility and reference specimen test results are available on request. Impact Sound Transmission Impact sound transmission measurements were made in accordance with ASTM E492-90, "Standard Test Method for Laboratory Measurement of Impact Sound Transmission Through Floor-Ceiling Assemblies Using the Tapping Machine". This test used the standard tapping machine and -Page 3 of 11- This Page Alone is Not a complete Report Page 22 of 42 B3463.15 Ogden Residence STC IIC Report RNS Acoustics 2021/02/24 the prescribed four impact positions on the floor. The Impact Insulation Class (IIC) was determined in accordance with ASTM E989-89, "Standard Classification for Determination of Impact Insulation Class (IIC)". These measurements are also in accordance with ISO 140- 6, "Laboratory Measurements of Impact Sound Insulation of Floors", except that the tapping machine positions are not randomly selected. This difference is believed to be insignificant. The Weighted Normalized Impact Sound Pressure Level (Ln.w) was determined in accordance with ISO 717-2, "Acoustics -Rating of Sound Insulation in Buildings and of Building Elements -Part 2: Impact Sound Insulation". One-third octave band sound pressure levels were measured for 30 seconds at each microphone position in the receiving room and then averaged to get the average sound pressure level in the room. Five sound decays were averaged to get the reverberation time at each microphone position in the receiving room. These times were averaged to get the spatial average reverberation times for the room. The space average sound pressure levels and the spatial average reverberation times of the receiving room were used to calculate impact transmission values. For impact sound transmission, the lower room is the receiving room. -Page 4 of 11-NIC·CMC This Page Alone is Not a Complete Report Page 23 of 42 RESULTS B3463.15 Ogden Residence STC IIC Report RNS Acoustics 2021/02/24 Results of the airborne sound transmission loss measurements of Floor "G" are given in Table 2 and Figure 1. Results of the impact sound transmission measurements of this floor construction are given in Table 3 and Figure 2. The Tables also give the 95% confidence limits. Acoustical measurement in rooms is a sampling process and as such has associated with it a degree of uncertainty. By using enough microphone and loudspeaker positions, the uncertainty can be reduced and upper and lower limits assigned to the probable error in the measurement. These limits are called 95% confidence limits. They are calculated for each test according to the procedures in ASTM E90 and E492 and must be less than upper limits given in the standards. These confidence limits do not relate directly to the variation expected when a nominally identical specimen is built, installed and tested (repeatability). Nor do they relate to the differences expected when nominally identical specimens are tested in different laboratories (reproducibility). -Page 5 of 11-taC-Clac This Page Alone is Not a Complete Report Page 24 of 42 83463.15 Ogden Residence STC IIC Report RNS Acoustics 2021102/24 Table 2: Airborne sound transmission loss measurements of Floor "G", TLF-94-045/046.

The higher the value of either rating, the better the floor performance. Thus, the rating is intended to correlate with subjective impressions of the sound insulation provided against the sounds of speech, radio, television, music, office machines and similar sources of noise characteristic of offices and dwellings. In applications involving noise spectra that differ markedly from those referred to above (for example, heavy machinery, power transformers, aircraft noise, motor vehicle noise), the STC and Rw are of limited use. Generally, in such applications it is desirable to consider explicitly the noise spectra and the insulation requirements. Impact Insulation Class And Weighted Normalized Impact Sound Pressure Level The Impact Insulation Class (IIC) (ASTM E989) and the Weighted Normalized Impact Sound Pressure Level (Ln,w) (ISO 717-2) are single-figure rating schemes intended to rate the effectiveness of floor-ceiling assemblies at preventing the transmission of impact sound from the standard tapping machine. The higher the value of the rating, the better the floor performance. The ASTM E989 and the ISO 717 rating curves are identical. The major difference in the fitting procedure is that the ISO standard allows unfavorable deviations to exceed 8 dB; the ASTM E989 standard does not. When this 8 dB requirement is not invoked, the two ratings are related by the equation IIC = 110 -L., w Extended Frequency Range Standard test procedures require measurements in 1/3- octave bands over a specified frequency range (125 to 4000 Hz for ASTM E90 and 100 to 3150 Hz for ASTM E492). Within those ranges, reproducibility has been assessed by inter-laboratory round robin studies. The standards recommend making measurements and reporting results over a larger frequency range, and this report presents such -Page 10 of 11-MC-ctac This Page Alone is Not a Complete Report Page 290142 B3463.15 Ogden Residence STC IIC Report RNS Acoustics 2021/02/24 results, which may be useful for expert evaluation of the specimen performance.

The intent of our two site visits, conducted on March 22nd and April 19th, 2013, was to perform airborne and impact sound transmission testing on one floor/ceiling assembly separating vertically stacked condominium units before and after the installation of a suspended gypsum wallboard (GWB) ceiling. The summary provided herein is based upon our test data and information extracted from architectural drawings provided by Stuart & Associates. Performance Ratings of Interior Building Components A comparison of the effectiveness of a partition in attenuating airborne and impact sound is typically presented in the form of Sound Transmission Class (STC) and Impact Insulation Class (IIC) ratings. The STC is a single-number rating of a wall or floor/ceiling assembly's effectiveness in isolating airborne sound. The IIC rating is limited to floor/ceiling assemblies and describes an assembly's effectiveness in isolating impact noises, such as those caused by foot traffic. The Noise Isolation Class (NIC) is a single number rating derived from the measured values of noise reduction. The rating provides an evaluation of the sound isolation between two enclosed spaces that are acoustically connected by one or more paths. The STC and NIC ratings are similar. However, NIC is a field rating; STC is a laboratory rating and discounts field conditions like absorption in the receiving room and partition size. For all three ratings, STC, UC, and NIC, increasing values correspond to increasing sound isolation. Testing assemblies in accordance with ASTM E90 (Standard Test Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions) and ASTM E492 (Standard Test Method for Laboratory Measurement of Impact Sound Transmission Through Floor- Ceiling Assemblies Using the Tapping Machine) results in STC and UC ratings, respectively. Ratings stated in terms of STC or IIC imply laboratory ratings. When the airborne and impact transmission loss of an assembly is measured in an actual installation, the ratings are presented as ASTC and FIIC, denoting "apparent" STC rating and "field" IIC rating. Field measurements result in NIC, ASTC, and FIIC ratings. Acoustica l performance ratings of wall and floor/ceiling assemblies are addressed in Section 1207 of the current International Building Code (IBC), "Sound Transmission ". Minimum laboratory ratings of STC-50 and IIC-50 and field ratings of ASTC-45 and FIIC-45 are listed in the Code. The five point reduction accounts for a drop in performance due to field conditions. Because the field installation of a partition and the field test conditions are not as well controlled as in a laboratory, a properly constructed partition usually tests three to five points lower than its laboratory rating. Survey Procedures and Observations We measured the airborne and impact sound transmission through the floor/ceiling assembly before and after the installation of a suspended GWB ceiling using an Ivie Technologies IE-45 Real Time Analyzer, an amplified speaker and a Cesva MIO0S tapping machine. The Ivie Real Time Analyzer, model IE-45, meets ANSI 51.4 criteria for a Type 2 sound level meter.

ASTC/NIC Testing The airborne sound t ransmission through the floor/ceiling assembly was tested between the Second Floor Unit A and Third Floor Unit A, with the Second Floor space as the source room and the Third Floor space as the receiving room. Random broadband noise was generated in the source room using an amplified speaker and a pink noise generator. The test noise was measured in the source room in each 1/3 octave band between 125 and 4,000 Hz generally following ASTM E336 (Standard Test Method for Measurement of Airborne Sound Insulation in Buildings) using the Ivie Real Time Analyzer. Similarly, the test noise was measured in the receiving room. The difference between the source and receiver room levels in each 1/3 octave band is the Noise Reduction (NR). From the NR's in each band, the NIC rating is determined following ASTM E413 (Classification for Rating Sound Insulation). ASTC ratings are determined from the transmission loss {TL} values of the partition. These Tls are calculated by applying adjustments to the NR in each 1/3 octave band. The adjustments consider the test partition area and the receiver room absorption. The receiving room absorption is calculated using the receiver room volume and the measured reverberation time. Background sound levels are measured in the receiving rooms to discount any external noise that may have influenced the readings. Ideally, to properly follow ASTM guidelines for ASTC testing, the test rooms should be empty and acoustically hard. The test assemblies should not be offset between rooms and should have minimum dimensions of 7.5-ft x 9-ft with a minimum area of 60-ft2• The test rooms should have a minimum and maximum volume of 1,400-ft3 and 5,297-ft3, respectively. The room volume requirements exist as a guideline so that the lowest frequencies of interest are diffuse in the room and so that the room effect, or attenuation due to room volume and absorption, is minimized. The tested room volumes were 16,087-ft3 and 13, 716-ft3 in the "Before" and "After" conditions, respectively. Because the volumes of the test spaces exceed the guidelines in the ASTM standard, the proper metric to report is the NIC rating. The ASTC rating of the floor/ceiling assembly can be measured after the interior partitions are installed in two stacked units. Since only the 2nd Floor spaces were finished in this building, our airborne sound transmission measurements resulted in NIC ratings. Each space was unfurnished during the test, and the source and receiver rooms are not offset. FIIC Testing The FIIC of the floor/ceiling assembly was tested between the same spaces; however, the source and receiver rooms were reversed. The procedure for performing FIIC testing is standardized in ASTM E1007 (Standard Test Method for Field Measurement of Tapping Machine Impact Sound Transmission through Floor-Ceiling Assemblies and Associated Support Structures). As an impact source, we utilized a Cesva model MIO0S Tapping Machine. The machine's construction conforms to the specifications in ISO 140/IV- 1978(E). Sound pressure levels and reverberation time in the receiver room were measured utilizing the same equipment as for the NIC testing. The tapping machine has five steel hammers, each with a weight of approximately 1.1 pounds, equally spaced in a line with about 15. 7-in. between the two end hammers. The machine delivers 10 impacts per second at equal intervals. The spectrum of the noise in the receiving room can be influenced by the location of the tapping machine on the floor-ceiling assembly. For our testing purposes, and in accordance with ASTM E1007, the tapping machine was located at four different positions in the source room (refer to Figure 1). The locations and orientation of the joists were estimated in the field.

Tapping machine positions During tapping machine operation, the resulting sound pressure level was measured in the receiving room for each position in 1/3 octave bands from 100 to 3150 Hz, and the four measurements were averaged. The normalized impact sound pressure level was calculated considering the adjustments for each room's absorption based on our reverberation time measurements. The resulting FIIC rating for each assembly was then established in accordance with ASTM E989 (Standard Classification for Determination of Impact Insulation Class). Ideally, to properly follow ASTM guidelines for FIIC testing, the rooms should not be offset. In addition, the receiving room should have a volume of at least 2,100-ft3• Since each Unit A has an approximate volume of 13,716 ft3and 16,256 ft3 with and without the GWB ceiling, respectively, the volume requirements were met in each space. Each space was unfurnished during the testing, and the source and receiver rooms are not offset. Based on the architectural drawings and correspondence with Stuart & Associates, the floor/ceiling assembly consists of the following components: The "Before" condition without a GWB ceiling: • ¾" wood flooring • ¾" wood subflooring • 3"x14" wood joists supported on lS"xlS" wood beams and columns with saddles The "After" condition with a GWB ceiling: • ¾" wood flooring • ¾" wood subflooring • 3"x14" wood joists supported on 15"x15" wood beams and columns with saddles • Kinetics ICW hanger • Cold rolled channel • GWB furring channel • 3.5" Fiberglass batt insulation • Two layers of 5/8" GWB The following observations were made during the site visit on 3/22/2013: • The 2nd Floor and 3rd Floor Unit A spaces had full-height demising walls between the unit and the public corridor.
