Description / Abstract:
This test method covers the measurement of sound absorption in a
reverberation room by measuring decay rate. Procedures for
measuring the absorption of a room, the absorption of an object,
such as an office screen, and the sound absorption coefficients of
a specimen of sound absorptive material, such as acoustical ceiling
tile, are described.
