1、Designation: E966 10Standard Guide forField Measurements of Airborne Sound Attenuation ofBuilding Facades and Facade Elements1This standard is issued under the fixed designation E966; 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 guide provides methods to measure the sound isolation of a room from outdoor sound, and toevaluate t
3、he sound transmission or apparent sound transmission through a particular facade of theroom or an element of that faade such as a window or door. Measurements from outdoors to indoorsdiffer from measurements between two rooms. The outdoor sound field is not diffuse and thetransmission of that sound
4、through the structure is a function of the outdoor sound angle of incidence.The outdoor-indoor transmission loss values obtained with this guide are not expected to be the sameas that obtained in laboratory or other tests between two rooms using diffuse incident sound. At thistime, there are insuffi

For this reason, this guide provides alternative test procedures for themeasurements of facade field level reduction and transmission loss.This guide is part of a set of standards for evaluatin

Others in this set cover the airborne sound transmission lossof an isolated partition element in a controlled laboratory environment (Test Method E90), thelaboratory measurement of impact sound transmission throu
7、gh floors (Test Method E492), themeasurement of airborne sound transmission in buildings (Test Method E336), the measurement ofimpact sound transmission in buildings (Test Method E1007), and the measurement of soundtransmission through a common plenum between two rooms (Test Method E1414).1. Scope1.
8、1 This guide may be used to determine the outdoor-indoornoise reduction (OINR), which is the difference in soundpressure level between the free-field level outdoors in theabsence of the structure and the resulting sound pressure levelin a room. Either a loudspeaker or existing traffic noise oraircra
9、ft noise can be used as the source. The outdoor soundfield geometry must be described and calculations must ac-count for the way the outdoor level is measured. These resultsare used with Classification E1332 to calculate the singlenumber rating outdoor-indoor noise isolation class, OINIC.Both OINR a
10、nd OINIC can vary with outdoor sound incidenceangle.1.2 Under controlled circumstances where a single faade isexposed to the outdoor sound, or a faade element such as adoor or window has much lower transmission loss than the restof the faade, an outdoor-indoor transmission loss, OITL(u), orapparent
11、outdoor-indoor transmission loss, AOITL(u), may bemeasured using a loudspeaker source. These results are afunction of the angle of incidence of the sound field. Bymeasuring with sound incident at many angles, an approxima-tion to the diffuse field transmission loss as measured betweentwo rooms can b
12、e obtained. The results may be used to predictinterior sound levels in installations similar to that tested whenexposed to an outdoor sound field similar to that used duringthe measurement. The single number ratings of apparentoutdoor-indoor transmission class,AOITC(u), usingAOITL(u)and field outdoo
13、r-indoor transmission class, FOITC(u), usingOITL(u) may be calculated using Classification E1332. Theseratings also may be calculated with the data obtained fromreceiving room sound pressure measurements performed atseveral incidence angles as discussed in 8.6.1.3 To cope with the variety of outdoor
