Now that you have downloaded the ISO 3740 PDF for free, you may wonder what it contains and how to use it. Here are some key points to know about the standard:
ISO 3740 gives guidance for the use of a set of twelve basic International Standards (see Tables 1, 2 and 3 in the PDF) describing various methods for determining sound power levels from all types of machinery, equipment and products[^1^].
It provides guidance on the selection of one or more of these standards, appropriate to any particular type of sound source, measurement environment and desired accuracy[^1^]. The guidance given applies to airborne sound.
It is for use in the preparation of noise test codes (see ISO 12001) and also in noise emission testing where no specific noise test code exists[^1^]. Such standardized noise test codes can recommend the application of particular basic International Standard(s) and give detailed requirements on mounting and operating conditions for a particular family to which the machine under test belongs, in accordance with general principles given in the basic standards.
ISO 3740 is not intended to replace any of the details of, or add any additional requirements to, the individual test methods in the basic International Standards referenced[^1^].
ISO 3740 is the third edition of the standard and was published in February 2019. It replaces the previous edition from 2000[^2^].
ISO 3740 is an international standard that specifies the methods for determining the sound power levels of noise sources using sound pressure[^3^]. Sound power level is a quantity that describes the total acoustic energy emitted by a sound source per unit time. It is independent of the distance from the source and the acoustic environment. It is expressed in decibels (dB) relative to a reference value of 1 picowatt (pW).
Sound power level is useful for comparing the noise emission of different sound sources and for predicting the sound pressure level at a given distance from the source. It can also be used for noise control purposes, such as setting limits or targets for noise emission or designing noise reduction measures.
