Organization: ASA
Publication Date: 28 February 2006
Status: active
Page Count: 20
scope:

This standard defines a simple numerical method for rating the expected speech-interfering aspects of noise using acoustical measurements of the noise. The relevant acoustical characteristics of the noise are summarized in terms of a single-valued index known as the speech interference level. The application of the measure is intended for natural speech.

NOTE The speech interference level is related to the speech intelligibility index (ANSI S3.5-1997 (R2002) and to A-weighted sound level (ANSI S1.42-2001 (R 2006)).
