ASTM E90-2004实验室测量建筑物隔墙和构件的空气声音传输损失的标准试验方法

ASTM E90-2009实验室测量建筑物隔墙和构件的空气声音传输损失的标准试验方法

Sound transmission loss as defined in Terminology C 634, refers to the response of specimens exposed to a diffuse incident sound field, and this is the test condition approached by this laboratory test method. The test results are therefore most directly relevant to the performance of similar specimens exposed to similar sound fields. They provide, however, a useful general measure of performance for the variety of sound fields to which a partition or element may typically be exposed. In laboratories designed to satisfy the requirements of this test method, the intent is that only significant path for sound transmission between the rooms is through the test specimen. This is not generally the case in buildings where there are often many other paths for soundsx2014;flanking sound transmission. Consequently sound ratings obtained using this test method do not relate directly to sound isolation in buildings; they represent an upper limit to what would be measured in a field test. This test method is not intended for field tests. Field tests shall be performed according to Test Method E 336. Note 28212;The comparable quantity measured using Test Method E 336 is called the apparent sound transmission loss because of the presence of flanking sound transmission. 1.1 This test method covers the laboratory measurement of airborne sound transmission loss of building partitions such as walls of all kinds, operable partitions, floor-ceiling assemblies, doors, windows, roofs, panels, and other space-dividing elements. 1.2 Laboratories are designed so the test specimen constitutes the primary sound transmission path between the two test rooms and so approximately diffuse sound fields exist in the rooms. 1.3 Laboratory Accreditation8212;The requirements for accrediting a laboratory for performing this test method are given in Annex A4. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.

ASTM E2249-2019用声强法对建筑物隔墙和构件的空气传播损失进行实验室测量的标准试验方法

5.1x00a0;This test method can be used to obtain an estimate the transmission loss of building elements in a laboratory setting where the source room and the specimen mounting conditions satisfy the requirements of Test Method E90. The acceptability of the receiving room will be determined by a set of field indicators that define the quality and accuracy of the intensity estimate. 5.2x00a0;By appropriately constructing the surface over which the intensity is measured it is possible to selectively exclude the influence of sound energy paths including the effects from joints, gaps as well as flanking sound paths. This method may be particularly useful when accurate measurements of a partition can not be made in an Test Method E90 facility because the partition sound insulation is limited by flanking transmission involving facility source and receiver room surfaces, (for example, the path from the source room floor to the receiver room floor via the isolators and the slab supporting the two). Annex A3 discusses this in detail. 5.3x00a0;The discrete point method allows the mapping of the radiated sound intensity which can be used to identify defects or unique features (2) of the partition. 5.4x00a0;Current research reported in the literature indicate that there exists a bias between measures of transmission loss obtained using the intensity technique and those obtained using the conventional two room reverberation technique (for example, Test Method E90, (3) and (4)). Appendix E provides estimates of the bias that might be expected. Despite the presence of a bias, no corrections are to be applied to the measured data obtained by this test method. 1.1x00a0;This test method covers the measurement of airborne sound transmission loss of building partitions such as walls of all kinds, operable partitions, floor-ceiling assemblies, doors, windows, roofs, panels and other space-dividing building elements. It may also be have applications in sectors other than the building industry, although these are beyond the scope. 1.2x00a0;The primary quantity reported by this standard is Intensity Transmission Loss (ITL) and shall not be given another name. Similarly, the single-number rating Intensity Sound Transmission Class (ISTC) derived from the measured ITL shall not be given any other name. 1.3x00a0;This test method may be used to reveal the sound radiation characteristics of a partition or portion thereof. 1.4x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5x00a0;This standard does not purport to address all of the safety concerns, if any, associated w......
