Acoustics. Laboratory measurement procedures for ducted silencers and air-terminal units. Insertion loss, flow noise and total pressure loss Ingestion-build-279162 such as the model defined1 Scope This International Standard specifies methods for determining the insertion loss, in frequency bands, of ducted silencers with and without airflow, the sound power level, in frequency bands, of the flow noise (or regenerated sound) generated by ducted silencers, the total pressure loss of silencers with airflow, and the transmission loss, in frequency bands, of air terminal units. The measurement procedures are intended for laboratory
