3、ting 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 interior part
4、 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 element in
5、 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 field (Gu
6、ide 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 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
8、or-coveringmaterials.1.3 This test method defines several procedures and metricsto assess either the apparent performance of the nominallyseparating floor-ceiling or the isolation of a receiving roomfrom the sound produced by the operation of the tappingmachine. The receiving room may be the space d
9、irectly belowthe tapping machine or, in some cases, any separated space thatreceives sound from the operation of the tapping machine. 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
10、ngs include the effect offlanking transmission. Efforts to suppress flanking are notpermitted. 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
11、lized impact soundrating (NISR), and the absorption normalized impact soundpressure levels (ANISPL) and apparent impact insulation class(AIIC).1.4 The ISPL and ISR may be measured and reportedbetween any two specific rooms or usage areas where thesource room area is large enough to accommodate the t
12、appingmachine positions and the receiving room volume is suffi-ciently large to accommodate the microphone positions. For allother measures and ratings in this standard, restrictions such asminimum room volume or dimensions or maximum roomabsorption are imposed. Thus, conditions may exist that willn
13、ot allow RTNISPL (NISR) or ANISPL (AIIC) to be deter-mined.1.5 Where a separating floor-ceiling assembly is composedof parts that are constructed differently on the receiving room(ceiling) side, it is not possible to determine the ANISPL andAIIC of the individual elements or portions of the assembly
14、. Inthis situation, the measurement will be of the compositestructure, not of an individual element.1This test method is under the jurisdiction ofASTM Committee E33 on Buildingand Environmental Acoustics and is the direct responsibility of SubcommitteeE33.03 on Sound Transmission.Current edition app

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-th
42、ird octave band spectrum of the averagesound pressure level produced by the tapping machine in thereceiving room located beneath or near 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 ma
43、chine position. The background noisemeasurement and each tapping level measurement are con-ducted in the same way, whether by a single sweep or multiplemeasurements at fixed microphone positions.4.3 If appropriate, the measured impact sound levels areadjusted for the background noise.4.4 The adjuste
44、d impact sound pressure levels can be used(1) without normalization, (2) normalized to a standard rever-beration time, or (3) normalized 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
45、be determined. To determine absorption, the vol-ume of the receiving room must also be calculated frommeasured room dimensions.5. Significance 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
46、 of the floor-ceilingassembly, such as its weight, surface properties, mounting oredge restraints, stiffness, and internal damping; (2) the degreeof flanking transmission through associated structures; and (3)the acoustical response of the receiving room.5.2 The standardized tapping machine specifie
47、d in 6.1.1produces a continuous series of uniform impacts at a uniformrate on a floor-ceiling assembly to allow accurate and repro-ducible 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 femalef
48、ootsteps or to simulate the weight of a human walker. Also,measurements described in this method and ratings based onthe results are restricted to a specific frequency range. Thus thesubjectively annoying creak or boom generated by humanfootfalls on a limber floor-ceiling assembly may not beadequate
49、ly evaluated by this test method.5.3 Laboratory Test Method E492 calls for highly diffusesound fields and the suppression of flanking 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 buildings. Highly diffusefields are seldom found and the nature of structure-borneflanking transmission can vary widely. I
