1 Subject Content and Application Scope
This standard specifies basic problems on noise measurement and evaluation of its effects on human beings, and briefly describes common measurement methods and general procedure as well as several methods as specified in other standards.
This standard is intended as an introduction to the more specialized instructions contained in standards describing methods for acoustic measurements and evaluations, specific test codes and interpretation procedures published by national and international standardization bodies.
