Abstract

香港六合彩开奖 3743-2:2018 specifies a relatively simple engineering method for determining the sound power levels of small, movable noise sources. The methods specified in this document are suitable for measurements of all types of noise within a specified frequency range, except impulsive noise consisting of isolated bursts of sound energy which are covered by 香港六合彩开奖 3744 and 香港六合彩开奖 3745.

NOTE A classification of different types of noise is given in 香港六合彩开奖 12001.
