GB/T 19512-2004 "Acoustics - Measurement of sound attenuation of silencers in situ" specifies methods for measuring the insertion loss and airflow regenerated noise of silencers used in ventilation and air conditioning systems, as well as in power equipment (such as fans, compressors, and engines) under installed conditions (non-laboratory environments). This standard is applicable for evaluating the acoustic performance of silencers under actual operating conditions.
