Methods for the Measurement of Sound Pressure Levels
CSA Standard Z107. 2, Methods for the Measurement of Sound Pressure Levels is the second in a series of Standards on Noise Pollution. This Standard makes recommendations to assist in the development of noise measurement techniques that are satisfactory for use under various environmental conditions.
The CSA Committee on Noise Pollution decided to adopt ANSI Standard S1.13 rather than prepare a new Standard to avoid duplication.
The adoption of ANSI Standard S1.13—1971 as a new CSA Standard Z1072. has been formally approved by the CSA Committee on Noise Pollution and the Standards Policy Board.
General recommendations arc given to assist in the development of noise measurement techniques that are satisfactory for use under various environmental conditions.
The measurement of sound produced by sources which radiate directly into the air is given first priority. The airborne sound pressures may be partially attributable to sound transmission along structural pathways and reradiation from solid (or fluid) bodies.
Primary consideration is given to the measurement of sound created as a by-product of the principle function of the source. The methods may also be applied to other sources which are intended to generate sound. For example, measurements may be desired of the sound pressure generated by an alarm device operating in the presence of multiple noise sources.
This standard does not consider sound pressure level measurements which are obtained for the purpose of determining the sound power radiated by a source.
