National and international standards pertaining to noise and speech

There has been considerable recent activity in the development of standards relating to bioacoustics, especially in the areas of noise, hearing, and speech. Most of these national and international standards are written within the framework of the Bioacoustic Committee, S3, of the American National Standards Institute. This paper briefly describes how standards for bioacoustics are developed and used. Many of the new standards on noise, hearing, and speech are also described.
