Electroacoustics - Sound level meters -- Part 1: Specifications
IEC 61672-1:2013 gives electroacoustical performance specifications for three kinds of sound measuring instruments: - time-weighting sound level meters that measure exponential-time-weighted, frequency-weighted sound levels; - integrating-averaging sound level meters that measure time-averaged, frequency-weighted sound levels; and - integrating sound level meters that measure frequency-weighted sound exposure levels. Sound level meters specified in this standard are intended to measure sounds generally in the range of human hearing. Two performance categories, class 1 and class 2, are specified in this standard. Acceptance limits for class 2 are greater than, or equal to, those for class 1. This standard is applicable to a range of designs for sound level meters. A sound level meter may be a self-contained hand-held instrument with an attached microphone and a built-in display device. A sound level meter may be comprised of separate components in one or more enclosures and may be capable of displaying a variety of acoustical signal levels. Sound level meters may include ext
