Description / Abstract:

This Standard specifies the laboratory physical measurement procedure, calculation, and results reporting for quantifying the performance of noise canceling and noise discriminating microphones in a diffuse noise field.

Purpose

The purpose of this Standard is to describe procedures designed to measure the noise canceling performance of noise canceling and noise discrimination microphones in a diffuse sound field. This method provides a measure of merit, the Noise Canceling Index, which can be used to quantify the overall performance of a microphone in canceling or discriminating noise when compared to a laboratory quality pressure microphone meeting ANSI S1.12-1967 (R 1997).
