ASA S1.13-2005 (R2010)

This standard specifies requirements and describes procedures for the measurement of sound levels in air at a single point inspace. These requirements and procedures apply primarily to measurements performed indoors but may be utilized in outdoor measurements under specified conditions. This is a fundamental standard applicable to a wide range of measurements and to sounds that differ widely in temporal and spectral characteristics; more specific American National Standards complement its requirements. A classification is given of the types of sound generally encountered, and the preferred descriptor for each type is identified. This standard is intended to be used by practitioners in the field as well as by members of the general public who have little or no special technical training in areas relating to acoustics. This is a replacement for a previous version of ANSI S1.13.
