ISO 15664:2025

This International Standard defines the procedures for noise control of mainly open plants. 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 noise procedures are outside the scope of this International Standard but should be considered); _ 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, on the basis of overall noise requirements for the plant. A schematic flowchart, reviewing the noise control process, is presented in annex A and a summary of action items is presented in annex B. NOTE Concerning specific engineering methods for the acoustic design and analysis of plants, use should be made of other standards and textbooks.
