Summary of Test Method4.1 This test method is a procedure for quantifying thesound from sources identified as the cause or potential cause ofnoise complaints in residential spaces.4.2 The sound generated by
18、 the source of interest may besteady, transient, or a mixture of the two. For each source ofinterest the steady sound and the highest transient sound aremeasured.4.2.1 Steady SoundThe measurement space is surveyedand the point at which the highest utilities-generatedA-weighted, slow response sound l
19、evel occurs is located (see9.1). The octave band andA-weighted sound levels at this pointare measured and reported.4.2.2 Highest Transient SoundThe highest utilities-generatedA-weighted, fast response sound level is measured atthe center of each measurement space and reported.4.2.3 These procedures
20、are repeated in all measurementspaces and for all sources, or combination of sources, ofinterest.5. Significance and Use5.1 This is an in situ method, that is, the measurements aremade at the actual installation. The sound levels measuredaccording to this test method should be representative for tha
21、tinstallation and for the quantity of acoustical absorptionactually, permanently present.5.2 The test method has the following limitations:5.2.1 The test method produces sound data which may becompared with applicable criteria or limits only if they are interms of the quantities measured in this tes
22、t method.5.2.2 The test method does not quantify certain subjectiveaspects of the sound environment that may be objectionable.These include pure tones, spectral content, and temporaldistribution.6. Measurement Space6.1 The measurement space shall be any space, individualroom, or enclosed portions of
23、 the residential space that areintended to be occupied by people.NOTE 1Examples of spaces expected to be measured are bedrooms,living rooms, kitchens, and finished basements. Examples of spaces thatare not expected to be measured are utility closets, closets, and carports.Examples of spaces that may
24、 or may not be measured are garages,unfinished basements, and hallways.6.2 For new construction, the measurements shall be madewith the space configured in the completed, but unfurnished,state.6.3 For currently inhabited spaces, the measurements shallbe made as furnished.6.4 Absorptive material shal
25、l not be added to the spacesolely for the purpose of influencing the measurements.7. Measurement Location7.1 The microphone height shall be between 1.1 and 1.3 mabove the floor, the approximate average of the sleeping,standing, and seated ear heights of an individual.7.2 The microphone shall be loca
26、ted no closer than1mtoany wall or other extended surface, except in spaces narrowerthan 2 m where the measurement shall be at a locationequidistant from the closest opposing walls. If the source ofinterest (built-in utility or appliance) protrudes from theextended surface, the measurement shall not
27、be made closerthan 1 m from the source.7.3 The reported measurement shall be made at the locationwithin each measurement space that meets the above require-ment and produces the highest sound level during the survey.7.4 The measurements shall be made with the minimumnumber of people in the measureme
28、nt space. Personnel shallnot occupy the direct line of sight between the source ofinterest and the sound level meter.8. Instrumentation8.1 The sound measurement system shall meet the require-ments of ANSI S1.4 for Type 1 sound level meters.8.2 Octave band or fractional band filters shall meet thereq
29、uirement of ANSI S1.11, Type 2, Order 3, or higher. If16 000 Hz measurements are to be made, a Type 1 filter mustbe used.8.3 Acoustic calibrators shall meet the requirements ofANSI S1.40.8.4 If measurements are to be made in a stream of movingair such as generated by a forced air heating system or a
30、irconditioner, place a windscreen over the microphone. Themotion of air over the microphone of the sound level meter cancause local air turbulence noise at the microphone. The meterwill respond to this turbulence noise and produce an erroneousreading. Placing a windscreen over the microphone will re
31、ducethis local turbulence.NOTE 2A windscreen having a diameter of at least 7 cm is recom-mended.9. Measurement Procedures9.1 Determining the Location of Sound Level MaximumSurvey each measurement space of interest to find the locationof the maximum A-weighted, slow response sound levelproduced by ea
32、ch sound source or combination of sources ofinterest. Walk slowly and quietly, first at 1 m from the insideboundary of the space, then at concentric paths about 1 m apart,while observing the sound levels. Note the location and soundlevel in the space where the level is the highest.NOTE 3An alternate
33、 method is to measure and record at fixedintervals such as 1 m, then note the highest level.E1574 98 (2014)29.2 Measurement Procedure for Steady SoundIn eachmeasurement space, repeat the following procedure for eachsource or combination of sources of interest:9.2.1 Place the microphone in the measur
34、ement space at thelocation of the sound level maximum as determined in 9.1.9.2.2 Measure the combined source sound and backgroundnoise. With the source of interest operating and all othercontrollable sound sources off, measure the octave band soundpressure level in each band from 31.5 Hz to 8000 Hz
35、inclusive,using the slow response on the sound level meter or averagesound level for periods depending on the octave band asfollows: 40 s for the 31.5 Hz band, 20 s for the 63 Hz band, 9s for the 125 Hz band and 5 s for bands above 125 Hz.NOTE 4The measurement may be made in 1/3-octave bands and the
36、data may be used to calculate the 1/1-octave bands levels.NOTE 5High frequency sound from television sets, computer moni-tors and intrusion sensors may be observed in the 16 000 Hz octave band.These should be reported as indicated in 10.1.8, especially if they areaudible to an occupant or if they co
37、ntribute to the A-weighted backgroundnoise as indicated in 3.2.1.9.2.3 Measure the Background NoiseShut off the sourceof interest and repeat the measurement of 9.2.2 using slowresponse or average band level consistent with 9.2.2.9.2.4 If, in each octave band, the background noise level(measured in 9
38、.2.3) is 10 dB lower than the correspondingoctave band level of the combined source sound and back-ground noise (measured in 9.2.2) then report the 9.2.2 mea-surements as the octave band levels of the sound generated inthe measurement space by the source of interest.9.2.5 If, in any octave band, bac
39、kground noise level is not 5dB lower than the corresponding measured octave band levelfor the combined background noise and source sound, thenindicate in the report that these octave band data are contami-nated by background noise.9.2.6 If in any octave band the background noise level(measured in 9.
40、2.3) is between 5 and 10 dB lower than thecorresponding octave band level of the combined source soundand background noise, adjust the 9.2.2 measurements inaccordance with Table 1 and report the adjusted level as theoctave band level of the sound generated in the measurementspace by the source of in
41、terest.9.3 Measure Procedure for Highest Transient NoiseForeach measurement space of interest, repeat the followingprocedure for each source of interest:NOTE 6Transient background noise could affect background as wellas source noise measurements.9.3.1 Place the microphone at the center of the space
42、ofinterest within the limits of Section 7. For nonrectangularspaces such as L-shaped rooms, break up the space intorectangles and measure at the center of each rectangle.9.3.2 Set the sound level meter to A-weighting, fast re-sponse.9.3.3 Measure the background noise. With the source ofinterest and
43、all other controllable sound sources shut off, notethe maximum A-weighted, fast response level for a 15-sinterval.9.3.4 Measure the combined source sound and backgroundnoise. Activate the source of interest and note the highest valueof the A-weighted, fast response level indicated by the meter.9.3.5
44、 If the A-weighted, fast response level of the back-ground noise is 10 dB lower than the highest A-weighted, fastresponse level of the combined source sound and backgroundnoise, then report the 9.3.4 measurements as highest transientsound level generated in the space by the source of interest.9.3.6
45、If the A-weighted, fast response level of the back-ground noise is not 5 dB lower than the level of the combinedsource sound and background noise, indicate in the report thatthe data are contaminated by background noise.9.3.7 If the A-weighted, fast response level of the back-ground noise is between
46、 5 and 10 dB lower than the highestA-weighted, fast response level of the combined source soundand background noise, then adjust the 9.3.4 measurements inaccordance with Table 1 and report the adjusted 9.3.4 measure-ments as highest transient sound level generated in the space bythe source of intere
