Scope

The standard specifies the substitution method for determining the insertion loss of ducted silencers. It sets out requirements for determining: – the insertion loss, in frequency bands, of silencers with and without air flow; – the sound power level, in frequency bands, of the flow noise generated by silencers; – the total pressure loss of silencers with air flow.
