ABSTRACT

This article presents the main data related to industrial acoustics. It starts with the quantities allowing for the physical characterization of noise. However, the interest of measuring noise only exists where there is an objective and an effect which can be detrimental to the human body. A physiological study of the noise is thus conducted in order to understand the notions of auditory sensation and discomfort. The measuring instruments used in acoustics are then presented: microphones, sound level meters, dosimeters, exposure meters and intensity meters.

Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

 INTRODUCTION

In the first part of this dossier on industrial acoustics, we'll define the acoustic quantities used to characterize noise, and then look at the measuring instruments: microphones, sound level meters, exposure dosimeters and intensity meters.

The second file [R 6 031] will deal with noise measurement and reduction methods.
