19、y3.1 DefinitionsFor definitions of terms pertaining toacoustics used in this test method, see Terminology C 634.3.2 Definitions of Terms Specific to This Standard:3.2.1 source roomthe room containing the tapping ma-chine.3.2.2 receiving rooma room below or adjacent to the floorspecimen under test in
20、 which the impact sound pressure levelsare measured.NOTE 1The receiving room is usually the room below the floorspecimen but it may also be on the same level, diagonally below, or, insome cases, it could be above the source room.3.2.3 impact sound pressure levelthe average sound pres-sure level in a
21、 specified frequency band produced in thereceiving room by the operation of the standard tappingmachine on the floor assembly, averaged over each of thespecified machine positions.3.2.4 normalized impact sound pressure levelthe impactsound pressure level normalized to a reference absorption of 10m2(
22、108 sabins).3.2.5 field impact insulation class (FIIC)a single-numberrating derived from measured values of normalized one-thirdoctave band impact sound pressure levels in accordance withClassification E 989.NOTE 2FIIC provides an estimate of the sound insulating perfor-mance of a floor-ceiling asse
23、mbly and associated support structures undertapping machine excitation.4. Summary of Test Method4.1 A standard tapping machine is placed in operation on afloor specimen. The transmitted impact sound is characterizedby the one-third octave band spectrum of the average soundpressure level produced by
24、the tapping machine in the receiv-ing room located beneath or adjacent to the floor specimenunder test.4.2 Since the spectrum and level depend on the absorptionof the receiving room, the impact sound pressure levels arenormalized to a reference absorption for purposes of compar-ing results obtained
25、in receiving rooms that differ in absorp-tion.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 of the floor-ceiling assem-bly, such as its weight, surface properties, mounting
26、 or edgerestraints, stiffness, and internal damping; (2) the acousticalresponse of the receiving room; and (3) the degree of flankingtransmission through associated structures.5.2 The standardized tapping machine specified in 7.1.1produces a continuous series of uniform impacts at a uniformrate on a
27、 test floor assembly and generates in the receivingroom broadband sound pressure levels high enough to makeaccurate and reproducible measurements possible. The tappingmachine, however, is not designed to simulate any one type ofimpact, such as male or female footsteps nor to simulate theweight of a
28、human walker. Thus the subjectively annoyingcreak or boom generated by human footfalls on a limber floorassembly may not be adequately evaluated by this test method.5.3 Test Method E 492 calls for the elimination of flankingsound transmission and for highly diffuse sound fields in thereceiving room.
29、 The problems associated with making acous-tical measurements in buildings are much more difficult thanthose met in the laboratory. In ordinary buildings, a greatvariety of test room shapes and sizes are encountered. Theamount of energy exchange at the nominal boundaries of thetest specimen, the man
30、ner of construction and factors such asstructure-borne flanking paths, for example, transmission in theside walls, varies widely. Highly diffuse fields are seldomfound in the field and the special efforts that would be requiredto simulate laboratory conditions and eliminate flanking soundare impract
31、ical.5.4 This test method accepts these limitations and givesmeasurement procedures for determining the average impactsound pressure level in nearly all cases that may be encoun-tered in the field. The test procedure evaluates the floor-ceilingassembly and adjacent structures as installed (including
32、structure-borne flanking paths). Results are not meant to beidentical to laboratory tests of the floor-ceiling assembly alone.Because of the uncontrollable factors mentioned in 5.1-5.3,caution must be used when using test results to predict theperformance of other floors with similar construction.

33、t is3Withdrawn4Available from American National Standards Institute (ANSI), 25 W. 43rd St.,4th Floor, New York, NY 10036.E100704e12preferable to confine the use of test results to the comparison ofclosely similar floors and supporting structures.6. Test Specimens6.1 TypesAll types of floor-ceiling a
34、ssemblies surfacedwith any type of material may be tested by this test method,including assemblies with floating floors or suspended ceilings.6.1.1 In all cases the test specimen should be installed inaccordance with customary field practice including normalconstraint and sealing conditions at the p
35、erimeter and at thejoints within the specimen.6.2 Aging of SpecimensTest specimens that incorporatematerials for which there is a curing process (for example,adhesives, plasters, concrete, mortar, and damping compound)shall age for a sufficient interval before testing. Aging periodsfor certain commo
36、n materials are recommended in TestMethod E 90 and summarized in Table 1 of this test method.6.3 Installation of Floor-Surfacing Materials:6.3.1 Since floor-surfacing materials of significant weight,such as carpets and pads, may exert a damping or restrainingeffect on the flexural motion of lightwei
37、ght floor structures, itis recommended that the entire area of the floor structure undertest be covered with the floor surfacing materials. Any excep-tion to this shall be noted in the test report.6.3.2 The installation or application of floor-surfacing ma-terials should be in accordance with manufa
38、cturers instruc-tion, especially in regard to cleaning and priming of thesubfloor.6.3.3 Floor-surfacing materials that are intended to be ap-plied with adhesive should not be tested merely laying on thesubfloor unless otherwise noted in the report.6.3.4 Although most floors are ready for immediate u
39、se afterbeing installed, it is recommended that measurements on floorswith adhesive-applied surfacing materials be deferred for atleast 24 h after installation to allow the adhesive to cure.6.4 Receiving Room VolumeIdeally, the receiving roomshould be large enough so that an approximately diffuse so
40、undfield exists in all measurement bands. In the field, sound fieldsare deemed acceptable down to 100 Hz if the room volume isgreater than 60 m3(2100 ft3), to 125 Hz if the room volume isgreater than 40 m3(1400 ft3), and to 160 Hz if the room volumeis greater than 25 m3(880 ft3).NOTE 3The requiremen
41、t at 125 Hz is obtained by assuming that aminimum of 10 room modes will provide a sufficiently good approxima-tion to a diffuse sound field; those at 100 and 160 Hz are obtained byrequiring the same average modal spacing as at 125 Hz.7. Tapping Machine7.1 Tapping Machine Specifications:7.1.1 This te
42、st method is based on the use of a standardizedtapping machine that conforms to the specifications given inISO 140/6. The tapping machine shall have five hammersequally spaced in a line. The distance between centerlines ofneighboring hammers shall be100 6 3 mm. Each hammer shallhave an effective mas
43、s of 500 6 6 g which falls freely from aheight of 40 6 3mm. The falling direction of the hammers shallbe perpendicular to the test surface to within 6 0.5. The partof the hammer carrying the impact surface shall be cylindricalwith a diameter of 30 6 0.2 mm. The impact surface shall beof hardened ste
44、el and shall be spherical with a curvature radiusof 500 6 100 mm. The tapping machine shall be self driven.The time between successive impacts shall be 100 6 20 ms.7.1.2 Since friction in the hammer guidance system canreduce the velocity of the hammer at impact, the tappingmachine shall be checked f
45、or friction between the hammersand the guidance system. Any friction found should be elimi-nated or reduced as much as possible. If the friction can not beeliminated, then the hammer weight or drop height can beincreased to compensate for this friction. In any event, thehammer weight and drop height
46、 shall not exceed the limitsgiven in 7.1.1.7.1.3 The bottoms of the machine supports shall be at least100 mm from the nearest hammer and capped with soft spongerubber pads about 5 mm thick so that the requirements in 7.2.1are satisfied.NOTE 4Investigations (1)5involving light-frame floating floors h
47、aveshown that both the resiliency of the tapping machine supports as well astheir spacing from the hammers significantly affect the impact soundpressure levels in frequency bands below 400 Hz.7.1.4 Following adjustment of the hammer drop in accor-dance with the specifications, the tapping machine is
48、 ready foruse on any floor, including those surfaced with soft or resilientmaterials.7.2 Operational Noise and Vibration:7.2.1 The tapping machine shall be constructed so that thevibratory excitation of the floor structure under test is dueprimarily to hammers impacting on the floor surface. Theone-
49、third octave band noise levels produced in the receivingroom by excitation of the floor due to the extraneous mechani-cal operations of the tapping machine shall be at least 10 dBbelow those produced by the impacting of the hammers. Thisrequirement can be verified by placing a strip of soft, veryresilient material under the impacting hammers. If there is atleast a 10-dB reduction in the sound pressure level in thereceiving room for each frequency band, extraneous vibra-tional transmission can be considered negligible.7.2.2 The presence of airborne sound flanking co
