MASKING OF PURE TONES AND SPEECH

Abstract

The masking effects of intense pure tones and bands of noise upon other pure tones and speech were investigated. Of perhaps special importance are the masking effects of very intense low frequency sounds, in that low frequency sounds are present near missile launch sites. On the basis of the test results, spread of masking functions were obtained that can be incorporated into procedures for the calculation of a new Articulation Index that will be valid for a much wider variety of noise conditions than heretofore possible.
