- the declared mean A-weighted sound power level, LWA,m;
- the declared mean A-weighted emission sound pressure level, LpA,m;
- the statistical adder for verification, Kv;
- the statistical upper limit A-weighted sound power level, LWA,c;
b) how acoustical and product information is to be published electronically or in hard-copy format in technical documents or other product literature supplied to users by the manufacturer or declarer;
c) the method for verifying the noise emission values that are declared by the manufacturer or declarer.
