Physically modeling sound sources enables flexible digital instruments

Evidence

There are different motivations for building such models. First of all, being able to model the functionalities of different parts of the system provides basic knowledge of the auditory system. Often, more than one mechanism affects the perceived characteristics of an auditory object, making the analysis of the results of psychoacoustic tests complicated. The complications can be mitigated when the effects of the mechanisms can be isolated in the computational domain, making the interpretation of the results easier. Second, a very important application for such models is the evaluation of audio quality. Modern acoustic systems comprise various transfers in the acoustic, signal processing, and telecommunication domains. The measurement of quality of reproduced audio cannot be performed with simple linear measures, which calls for the usage of models of human hearing for such tasks. Ideally, the fidelity of audio systems could be estimated by computing the auditory cues reaching the conscious level. The third application of auditory models is in the diagnostics of hearing-impaired patients. The symptoms of the patient would be characterized with specific psychoacoustic tests, and the attributes of the model of human hearing were adjusted until the symptoms were explained. Optimally, this would track down the reason for the symptoms. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 821 (#expands, via linked claim)
