Abstract

This Nordtest method specifies a practical test method for in situ measurements of permanently installed public address systems. The method is restricted to selected parameters, which can be used to evaluate a system's performance and to verify if a (comparable) system's technical specification is fulfilled.

Typical parameters that may be specified for a permanently installed public address system prior to the installation are described in Appendix 9.2 “Example of Technical Specification”.

This test method is assumed to be applied by those involved in specifying, supplying, installing or verifying public address systems.Adjustment of the public address system shall be carried out prior to the measurements.
