Acoustics. Declared noise emission values of information technology and telecommunications equipment Ingestion-build-83346 3 and Annex A)1 Scope This document is applicable to information technology and telecommunications equipment. It specifies: a) for a batch of equipment, the method for determining the following values: 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
