Scope1.1 This test method covers the measurement of the trans-mission of impact sound generated by a standard tappingmachine through floor-ceilin

7、g assemblies and associated sup-porting structures in field situations.1.2 Measurements may be conducted on all types of floor-ceiling assemblies, including those with floating-floor or sus-pended ceiling elements, or both, and floor-ceiling assembliessurfaced with any type of floor-surfacing or flo

The receiving room may be the space d

Thesource and receiving rooms as well as the floor-ceiling systemare identified and described in the test report. All measuredlevels and derivative single number rati

Available measures and their single number ratingsare the impact sound pressure levels (ISPL) and impact soundrating (ISR), the reverberation time normalized impact soundpressure levels (RTNISPL) and norma

38、. Summary of Test Method4.1 A standard tapping machine is placed in operation on afloor-ceiling assembly. The transmitted impact sound is char-acterized by the one-third octave band spectrum of the averagesound pressure level produced by the tapping machine in thereceiving room located beneath or ne

39、ar the floor-ceiling assem-bly.4.2 A complete test shall consist of one background noiselevel measurement, and four tapping level measurements, onefor each tapping machine position. The background noisemeasurement and each tapping level measurement are con-ducted in the same way, whether by a single

40、 sweep or multiplemeasurements at fixed microphone positions.4.3 If appropriate, the measured impact sound levels areadjusted for the background noise.4.4 The adjusted impact sound pressure levels can be used(1) without normalization, (2) normalized to a standard rever-beration time, or (3) normaliz

41、ed to a standard amount ofabsorption.4.5 If normalized values are to be reported, the reverbera-tion time (T2) or absorption (A2), or both, of the receivingroom must be determined. To determine absorption, the vol-ume of the receiving room must also be calculated frommeasured room dimensions.5. Sign

42、ificance and Use5.1 The spectrum of the noise produced in the receivingroom by the standard tapping machine is determined by (1) thesize and the mechanical properties of the floor-ceiling assem-bly, such as its weight, surface properties, mounting or edgerestraints, stiffness, and internal damping;

43、(2) the degree offlanking transmission through associated structures; and (3) theacoustical response of the receiving room.5.2 The standardized tapping machine specified in 6.1.1produces a continuous series of uniform impacts at a uniformrate on a floor-ceiling assembly to allow accurate and repro-d

44、ucible measurements of impact sound pressure levels in thereceiving room. The tapping machine is not designed tosimulate any one type of impact, such as male or femalefootsteps or to simulate the weight of a human walker. Also,measurements described in this method and ratings based onthe results are

45、 restricted to a specific frequency range. Thus thesubjectively annoying creak or boom generated by humanfootfalls on a limber floor-ceiling assembly may not beadequately evaluated by this test method.5.3 Laboratory Test Method E492 calls for highly diffusesound fields and the suppression of flankin

46、g sound transmis-sion in the laboratorys receiving room. This field test methoddoes not allow efforts to suppress flanking. In field tests,acoustical measurements are much more uncertain than in thelaboratory since a great variety of receiving room shapes andsizes are encountered in ordinary buildin

47、gs. Highly diffusefields are seldom found and the nature of structure-borneflanking transmission can vary widely; consequently, goodagreement between laboratory tests and field tests on similarfloor-ceiling assemblies should not be expected.5.4 Several metrics are available for specific uses:5.4.1 a

48、bsorption normalized impact sound pressure level(ANISPL) and apparent impact insulation class (AIIC)Thesemetrics are intended to evaluate the performance of thefloor-ceiling assembly and adjacent structures as installed(including structure-borne flanking paths). For these metrics,sound power from as

49、sociated support structures are attributedto the floor-ceiling assembly. Because these are measures of theapparent performance of the nominally separating floor-ceiling, the receiving room shall be the space directly under thetapping machine. ANISPL and AIIC may be reported if thereceiving room has a volume of at least 40 m3and the smallestdimension is at least 2.3 m. ANISPL and AIIC may bemeasured and reported only if, in all frequency bands neces-sary to calculate the AIIC, the receiving room absorption, A2,is less than:A2, 23V2/3!(1)wher
