Abstract : Bioacoustic criteria incorporating A-weighted sound levels have been widely adopted in industry and government; yet much of the noise data currently stored or in use by the Air Force is expressed in octave bands. The Air Force is finding it increasingly necessary to convert these data to equivalent A-weighted values. This report describes and illustrates a simple device--a dial-type calculator--with which such conversion can be made. Five different A-weighted conversions are provided: two for data expressed in the old octave bands, and three for data expressed in the newer set (preferred) of octave bands. (Author)
