Acoustics - Determination of sound power levels of noise from air-terminal devices, air-terminal units, dampers and valves by measurement in a reverberation test room (ISO/DIS 5135:2019); German and English version prEN ISO 5135:2019

Abstract

This document defines requirements for acoustic testing of air-terminal units, dampers and valves used in air diffusion and air distribution systems in reverberation rooms. It is based on the use of ISO 3741, which describes the acoustic test facilities, instrumentation and procedures to be used for precision grade determination of sound power levels in octave or one-third-octave bands of a noise source. This document also specifies the determination and the indication of the uncertainty given by the application of that measurement procedure. Furthermore it is ruled which data and in which way they are provided in the measurement report.
