Neutralizing the meaning of sound for sound quality evaluations
نویسنده
چکیده
Sound quality usually can be described by psychoacoustic magnitudes like loudness, sharpness or roughness. However, sometimes the meaning of a sound may strongly influence its subjective evaluation. In order to assess these effects, sounds „without meaning“ have to be realized. A frequently applied solution of this problem is to fill the temporal envelope of an original sound with pink noise. However, this procedure has the severe disadvantage that the original sound and the sound with no meaning differ in loudness. Therefore, a procedure is proposed, which can „neutralize“ the meaning of sound, and at the same time preserve the original loudness.

Incontrovertibly, the sense of hearing is one of the five most substantial human senses. In fact, the human ear receives sound and transmits to the human brain by the auditory organs. Hence, sound can be considered as one of the key tools of human communication with each other and the environment around them. Since acoustic has a profound impact on the body, soul, and the performance of human ...
