前言 声强测量的目的在于: 1.在啤酒厂背景噪声很高的出液机房中测量贴标鉴机全速工作时的噪声值。 2.检验贴标鉴机操作位置处的声压级是否低于该机生产厂的规定指标(85dB(A))。
Preface The purpose of the sound intensity measurement is to: 1. Measure the noise level at the full speed of the Labeler in the outlet room with a high background noise in the brewery. 2. Check whether the sound pressure level at the operation position of the labeling machine is lower than the specified index (85dB (A)) of the machine manufacturer.
