1、Designation: E3133 18Standard Test Method forLaboratory Measurement of Floor Impact Sound RadiationUsing the Tapping Machine1This standard is issued under the fixed designation E3133; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision,
2、 the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis test method is used to evaluate the impact sound radiation in the source room of various floorstruct
3、ures in a controlled laboratory environment. The method is similar to that used in Test MethodE492, and provided that the Test Method E492 laboratory facilitys source room meets the roomrequirements of this test method, this test can be performed simultaneously with the Test Method E492test. This te
4、st method does not require a separate receive room as the measurements are made in theroom that also contains the impact noise source. It is anticipated that a different standard will bedeveloped in the future to enable field measurement of floor impact sound radiation. Other relatedstandards includ

Scope1.1 This test method covers the laboratory

While the finished floor surface isusually the primary factor, it must be noted that the floorstructure below the finished floor also plays a major role in thelevel of noise generated in the source room
7、 by impacts to thefloor surface. As a result, the report must include a fulldescription of the complete floor structure and its support (forexample, perimeter support only, multiple point supports, orfull continuous support like a slab on grade). It is assumed thatthe impact sound generated by the t

No other units of measurement are included in thisstandard.1.6 This standard does not purport to address all of thesafety concerns, if any, associated

It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accor-dance with internationally recognize
