TEXTILE MACHINERY ACOUSTICS - DETERMINATION OF SOUND PRESSURE LEVELS AND SOUND POWER LEVELS EMITTED BY TEXTILE MACHINES - ENGINEERING AND SURVEY METHODS
01-05-2001
12-01-2013
Specifies engineering and survey methods applied to textile machinery with reference to ISO 3744 and ISO 3746 for measuring the sound pressure levels on a measurement surface enveloping the source and for calculating the sound power produced by the source. Specifies the test environment and instrumentation as well as techniques for obtaining the surface sound pressure level. Provides specifications for measuring the noise emitted by textile machines into the ambient air according to uniform methods. Also specifies the measurement of sound pressure levels at the operator position for specified typical conditions, with reference to ISO 6081.
