GUIDE FOR THE CLASSIFICATION NOTATION UNDERWATER NOISE AND EXTERNAL AIRBORNE NOISE

inactive
Organization: ABS
Publication Date: 1 May 2021
Status: inactive
Page Count: 46
scope:

This Guide outlines the process and criteria to obtain the underwater noise notation and external airborne noise notation. It provides requirements on acoustic instrumentation, test site conditions, measurement procedures for the underwater noise measurement and external airborne noise measurement. It also provides a description of post-processing of the measurement data.
