Abstract This standard makes the noise power emission level Lnpe) the basic measure of noise emission. This is the A-weighted sound power level of a source in bels. The reference sound power is 1pW. The relationship of the unit to other measures of sound power level and sound pressure level is specified. A method for obtaining Lnpe from sound power levels in octave or one-third octave frequency bands (50-10,000Hz) is given. The standard applies to all machinery and equipment that is essentially stationary and for which overall A-weighted sound power is a meaningful descriptor of noise emission. It revises and supersedes ANSI S1.23-1976 (R 1983) and ANSI S3.177-1975 /R 1980).
