Organization: ASA
Publication Date: 19 May 2000
Status: active
Page Count: 19
scope:

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).

Applications

The test method used in this Standard applies to measuring the noise canceling performance of noise canceling microphones, such as first and second order pressure gradient microphones, noise discriminating microphones, such as cardioid or shotgun microphones, and microphone systems, such as array microphones.
