Psychoacoustics Essays

Well this is mostly due to a lesser known field of science called psychoacoustics, the study of audiology and sound perception. Although you may not realize it now, psychoacoustics actually affects most people in their day to day lives, whether it’s via music listening or watching a movie, you’re almost always subject to the effects of psychoacoustics. With that being said, I’ll attempt to explain only a portion of psychoacoustics, including auditory masking, the process in which we perceive sound

1.7 Speech analysis One of the important characteristics of a speech waveform is the time-varying nature of the content of the speech pressure. Determination of the time-varying parameters of speech is a key area of analysis required in speech research. Another key area is classification of speech waveform segments into voiced or voiceless (mixed excitation is usually considered voiced). As mentioned previously, in the case where speech is voiced, the most important parameter is the fundamental

static at all. Hence, in this scenario, in order to perceive tone quality accurately, the shape of the amplitude envelope at the beginning of the sound has to be carefully determined. Grey (1977) used multidimensional techniques to investigate the psychoacoustic characteristics of musical timbre. This technique can allow researchers to construct a timbre space and to calculate the varied perceptual dimensions related to the acoustic characteristics of instrument sounds. Importantly, spectral shape of
