    Abstract - (Show below) - (Hide below)

    Specifies engineering and survey methods applied to textile machinery for measuring the sound pressure levels on a measurement surface enveloping the source and for calculating the sound power produced by the source. Coverage includes definitions, acoustic environment and instrumentation. Also gives detailed annexes.
