Acoustics - Noise control design procedures for open plant

This document defines the procedures for noise control of primarily open plants and the requirements on equipment suppliers for reporting and testing of noise.

It is applicable to the following:

—     specification of procedures for noise control during engineering of a new plant and modification/extension of existing plants (construction and commissioning noise procedures are outside the scope of this document);

—     definition of responsibilities of parties involved, viz. “end-user”, “engineering contractor” and “equipment supplier”;

—     description of general procedures to arrive at noise requirements for individual equipment, based on overall noise requirements for the plant.

Input to purchase specifications is presented in Annex A.

A schematic flowchart, reviewing the noise control process, is presented in Annex B and a summary of action items is presented in Annex C.

An example of an equipment noise data sheet is presented in Annex E.
