標(biāo)準(zhǔn)簡介
Applies to sound insulation between a pair of rooms. Determines the steady state (sup)1/3 octave band filtered white noise level difference and the receiving room equivalent absorption area from which the standardized level difference is derived. The results can be used to determine whether building elements have met acoustic specifications, e.g. Building Regulations.
