Noise emission measurements for regulatory purposes

Abstract

A review is given of the measurement needs attendant to regulation of the noise generated and emitted by commercial products.The emphasis is primarily on measurement procedures for use in conjunction with point-of-sale regulations as opposed to regulations on the noise which a source actually emits when in operation.The report is divided into three major parts. Part I is a discussion of overall measurement requirements and the type of data and information which are needed in order to promulgate regulations based on appropriate measurement techniques.Part II is designed as a checklist for the evaluation of the suitability of a noise measurement standard for a particular class of products or, in the absence of a suitable standard, as a framework for development of one.The intent is to identify and discuss in some detail those factors which can impact on the accuracy, precision, and applicability of a noise measurement process.Part III consists of a series of flow charts depicting the development of appropriate procedures for the measurement of product noise emission.

Howling Winds: Sound, Sense, and the Politics of Noise Regulation

“…However, an association was found between increasing levels of wind turbine noise and individuals reporting to be “very” or “extremely” annoyed. Within this particular field of research, the concept of “annoyance” has a very specific meaning and is commonly used to describe general disturbances caused by noises that cannot be measured or do not exceed prescribed decibel limits (Flynn et al 1977, 17). Moreover, these “annoying” noises do not pose a direct threat to one’s health or wellbeing, but do so indirectly by disturbing one’s day-to-day functioning and enjoyment of life.…”
