||Reference quantities for acoustical levels
||American Institute of Physics, Standards Dept., c/o AIDC, 64 Depot Road, Colchester, VT 05446, USA, 27 Oct. 1989. v, 4p.
||This standard specifies a set of reference quantities that conform largely to International Standard ISO 1683. However, the present standard provides a sound exposure reference level (20ÁPa2s), which ISO 1683 does not, and omits the sound energy and the sound energy density given in the ISO standard. The effect of different reference levels for vibration acceleration and vibration velocity is discussed in one appendix, and the manipulation of compound reference units (e.g., of sound pressure and distance) is illustrated in a second.
