Industrial pipe acoustic treatments investigation per ISO 15665

Abstract

Reducing noise levels in industrial environments are critical as exposure to high noise levels has been related to health issues like fatigue and stress that can compromise safety of workers. Many types of acoustic products can be applied to various noise emitting equipments in an effort to reduce the noise levels in industrial spaces. Jacketed pipe insulation is one such product applied across many industries for controlling pipe emitted noise emission. As with most products, standards for evaluating performance have been created to validate performance claims by manufacturer’s. For jacketed pipe insulation ISO 15665, an international standard defining a testing process for measurement of the acoustical performance of installed and jacketed pipe insulation systems, is the accepted testing method. The measurement process provides for the determination of the insertion loss of jacketed insulation applied to a pipe. A recently conducted study to identify the performance of over 30 variations of jacketed pipe insulation, including combinations of two types of insulation material, is presented herein.
