What is Masking?

Abstract

Three experiments are presented and analyzed in terms of a conventional definition of masking and a masking index conforming to this definition. It is demonstrated that, even though all of these experiments yield data permitting calculation of the masking index, at least three distinct processes lead to these data: signal masking, distortion of the sound wave form, and listener distraction. Either masking theories should take these three processes into account, or masking should be redefined. © 1962, American Association of Physics Teachers. All rights reserved.
