Acoustics. Measurements on silencers in situ Ingestion-build-50790 The minimum safety requirements specified1 Scope 1. 1 This International Standard specifies measurements on silencers in situ. It is applicable to measurements on silencers in practical applications for acoustic analysis, acceptance tests and similar evaluations. Results obtained in accordance with this International Standard cannot be compared to performance data obtained from laboratory measurements on ducted silencers in accordance with ISO 7235, partly because of different test
