IMPULSE NOISE - A BRIEF REVIEW

This paper contains a brief review of the results of recent research into impulse noise and its effects. It sets out the important parameters and the various methods of measurement to enable anyone familiar with the measurement of steady state noise also to measure impulse noise. The physical parameters necessary to describe an impulse noise are considered and their importance discussed. Methods and problems of the assessment of subjective loudness are considered including the use of the impulse sound level meter. The risk of hearing damage due to high levels of impulse noise is discussed and the conclusion reached that equivalent continuous noise level is a good measure of damage risk. Methods for calculating it are detailed. Equipment needed to measure impulse noise is also considered, including oscilloscopes, tape recorders, sound level meters and dosemeters. /Author/TRRL/
