ISO 3743-2 - Acoustics - Determination of sound power levels of noise sources using sound pressure - Engineering methods for small, movable sources in reverberant fields - Part 2: Methods for special reverberation test rooms
February 1, 2018 - ISO

This document specifies a relatively simple engineering method for determining the sound power levels of small, movable noise sources. The methods specified in this document are suitable for measurements of all types of noise within a specified frequency range, except impulsive...

DS/EN ISO 4869-2 - Acoustics – Hearing protectors – Part 2: Estimation of effective A-weighted sound pressure levels when hearing protectors are worn (ISO 4869-2:2018)
November 26, 2018 - DS

This document specifies three methods (the octave-band, HML and SNR methods) of estimating the A-weighted sound pressure levels effective when hearing protectors are worn. The methods are applicable to either the sound pressure level or the equivalent continuous sound pressure...

Purpose. The purpose of this Test Procedure is the development testing of the noise level generated by the engine intake system and the surface radiation, including validation. Foreword. None. Applicability. For component development. Note: Nothing in the specification, however,...

ASME PTC 36 - Measurement of Industrial Noise
August 3, 2018 - ASME

This Code provides guidelines for the following two methods of measuring near- and far-field sound levels: (a) Survey Method (Survey Grade). This method is used to expeditiously perform cursory measurements to assess acoustical performance of systems and equipment. This may consist of...

CSA Z107.56 - Measurement of noise exposure
January 1, 2018 - CSA

This Standard describes methods for determining the occupational noise exposure level of workers (Lex,T) using sampling techniques. Lex,T represents the long-term noise exposure of workers and is calculated from measurements of Leq,t (3 dB exchange rate) in the workplace....

DS/ISO 17201-3 - Acoustics – Noise from shooting ranges – Part 3: Sound propagation calculations
February 4, 2019 - DS

This document specifies methods of predicting sound exposure levels of shooting sound for a single shot at a given reception point. Guidelines are given to calculate other acoustic indices from the sound exposure level. The prediction is based on the angular source energy distribution...
