3、DUCTIONThis test method is part of a set of standards for 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 throug

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 airb
5、orne sound transmission loss of an isolated partition element 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 transmissi
6、on through building facades and facade elements in the 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 so
7、und generated by a standard tapping machinethrough floor-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-ceilin
8、g assemblies surfaced with any type of floor-surfacing 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 operat
9、ion of the tapping machine. Thereceiving room may be the 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
10、 test report. All measured levels and derivative single 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 reverber
11、ation time normalized impact sound pressure levels (RTNISPL) 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 us
12、age areas where the source roomarea is large enough to 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 m
13、aximum room absorption are imposed. Thus, conditions may exist that will not allow RTNISPL(NISR)or ANISPL (AIIC) to be measured.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 T

48、sorption.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 absorption, the volume of the receiving room must also be calculated from measured roomdimensions.5. Significance and Use5.1 The spectr
49、um 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 assembly, 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 continuous series of uniform impacts at a uniform rate ona floor-ceiling asse
