Measurement of Industrial Noise

scope:
This Code provides guidelines for the following two methods of measuring near- and far-field sound levels:
(a) Survey Method (Survey Grade). This method is used to expeditiously perform cursory measurements to assess acoustical performance of systems and equipment. This may consist of preliminary or limited measurements for further study and review, or for more in-depth follow-up work. Refer to ANSI/ASA S12.56/ISO 3746.
(b) Engineering Method (Engineering Grade). This method is used to perform precise field measurements for assessing acoustical performance and compliance with acoustical requirements. These types of measurements usually include an assessment of variability in the data and of uncertainty. Refer to ANSI/ASA S12.54/ISO 3744. General guidance for sound-level measurements is found in Nonmandatory Appendix B.
PURPOSE
The purpose of this Code is to recommend measurement procedures in a variety of acoustical environments, including settings influenced by background or extraneous noise. Generally, an A-weighted sound-pressure level (see Section 2) is used to quantify the sound emission of industrial equipment and facilities.
