Standard Test Method for Laboratory Measurement of Floor Impact Sound Radiation Using the Tapping Machine
|Publication Date:||1 April 2018|
This test method covers the laboratory measurement of impact sound radiation from floor structures using a standardized tapping machine. While the finished floor surface is usually the primary factor, it must be noted that the floor structure below the finished floor also plays a major role in the level of noise generated in the source room by impacts to the floor surface. As a result, the report must include a full description of the complete floor structure and its support (for example, perimeter support only, multiple point supports, or full continuous support like a slab on grade). It is assumed that the impact sound generated by the tapping machine in the test room is a good approximation to a diffuse sound field.
Measurements may be conducted on floor structures of all kinds, including those with floating-floor or suspended ceiling elements, or both, and floor-ceiling assemblies surfaced with any type of floor-surfacing or floor-covering materials.
This test method prescribes a uniform procedure for reporting laboratory test data in both one-third-octave-ban
Laboratory Accreditation-The requirements for accrediting a laboratory for performing this test method are given in Annex A2.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
