3、or evaluating the sound insulating properties ofbuilding elements and sound isolation between spaces. It is designed to measure in the field the impactsound isolation between rooms or to estimate lower limits for impact sound transmission through afloor-ceiling partition element installed as an inte
4、rior part of a building using a standard tappingmachine. Others in the set cover measurement of impact sound transmission through an isolatedfloor-ceiling assembly in a controlled laboratory environment (Test Method E492), the measurementof airborne sound transmission loss of an isolated partition e
5、lement in a controlled laboratoryenvironment (Test Method E90), the measurement of airborne sound isolation and airborne soundtransmission loss associated with building elements in the field (Test Method E336), the measurementof sound transmission through building facades and facade elements in the
6、field (Guide E966); and themeasurement of sound transmission through a common plenum between two rooms in a controlledlaboratory environment (Test Method E1414).1. Scope1.1 This test method covers the measurement of the transmission of impact sound generated by a standard tapping machinethrough floo
7、r-ceiling assemblies and associated supporting structures in field situations.1.2 Measurements may be conducted on all types of floor-ceiling assemblies, including those with floating-floor or suspendedceiling elements, or both, and floor-ceiling assemblies surfaced with any type of floor-surfacing
8、or floor-covering materials.1.3 This test method defines several procedures and metrics to assess either the apparent performance of the nominallyseparating floor-ceiling or the isolation of a receiving room from the sound produced by the operation of the tapping machine. Thereceiving room may be th
9、e space directly below the tapping machine or, in some cases, any separated space that receives soundfrom the operation of the tapping machine. The source and receiving rooms as well as the floor-ceiling system are identified anddescribed in the test report. All measured levels and derivative single
10、 number ratings include the effect of flanking transmission.Efforts to suppress flanking are not permitted. Available measures and their single number ratings are the impact sound pressurelevels (ISPL) and impact sound rating (ISR), the reverberation time normalized impact sound pressure levels (RTN
11、ISPL) andnormalized impact sound rating (NISR), and the absorption normalized impact sound pressure levels (ANISPL) and apparentimpact insulation class (AIIC).1.4 The ISPL and ISR may be measured and reported between any two specific rooms or usage areas where the source roomarea is large enough to
12、accommodate the tapping machine positions and the receiving room volume is sufficiently large toaccommodate the microphone positions. For all other measures and ratings in this standard, restrictions such as minimum roomvolume or dimensions or maximum room absorption are imposed. Thus, conditions ma
13、y exist that will not allow RTNISPL(NISR)or ANISPL (AIIC) to be determined.1.5 Where a separating floor-ceiling assembly is composed of parts that are constructed differently on the receiving room(ceiling) side, it is not possible to determine the ANISPL and AIIC of the individual elements or portio
14、ns of the assembly. In thissituation, the measurement will be of the composite structure, not of an individual element.1 This test method is under the jurisdiction of ASTM Committee E33 on Building and Environmental Acoustics and is the direct responsibility of Subcommittee E33.03on Sound Transmissi

Summary of Test Method4.1 Astandard tapping machine is placed in operation on a floor-ceiling assembly.The transmitted impact sound is characterizedby the one-third octave band spectrum of
44、the average sound pressure level produced by the tapping machine in the receiving roomlocated beneath or near the floor-ceiling assembly.4.2 Acomplete test shall consist of one background noise level measurement, and four tapping level measurements, one for eachtapping machine position. The backgrou
45、nd noise measurement and each tapping level measurement are conducted in the same way,whether by a single sweep or multiple measurements at fixed microphone positions.4.3 If appropriate, the measured impact sound levels are adjusted for the background noise.4.4 The adjusted impact sound pressure lev
46、els can be used (1) without normalization, (2) normalized to a standard reverberationtime, or (3) normalized to a standard amount of absorption.4.5 If normalized values are to be reported, the reverberation time (T2) or absorption (A2), or both, of the receiving room mustbe determined. To determine
47、absorption, the volume of the receiving room must also be calculated from measured roomdimensions.5. Significance and Use5.1 The spectrum of the noise produced in the receiving room by the standard tapping machine is determined by (1) the sizeand the mechanical properties of the floor-ceiling assemb
48、ly, such as its weight, surface properties, mounting or edge restraints,stiffness, and internal damping; (2) the degree of flanking transmission through associated structures; and (3) the acousticalresponse of the receiving room.5.2 The standardized tapping machine specified in 6.1.1 produces a cont
49、inuous series of uniform impacts at a uniform rate ona floor-ceiling assembly to allow accurate and reproducible measurements of impact sound pressure levels in the receiving room.The tapping machine is not designed to simulate any one type of impact, such as male or female footsteps or to simulate the weightof a human walker. Also, measurements described in this method and ratings based on the results are restricted to a specificfrequency range. Thus the subjectively annoying creak or boom generated by human footfalls on a limber floor
