Abstract.
An auditory model based on the psychophysics of hearing has been developed and tested.
The model simulates the normal ear or an impaired ear with a given hearing loss. Based
on reviews of the current literature, the frequency selectivity and loudness growth as
functions of threshold and stimulus level have been found and implemented in the model.
The auditory model was verified against selected results from the literature, and it was
confirmed that the normal spread of masking and loudness growth could be simulated in
the model. The effects of hearing loss on these parameters was also in qualitative
agreement with recent findings. The temporal properties of the ear have currently not
been included in the model.
As an example of a real-world application of the model, loudness spectrograms for a
speech utterance were presented. By introducing hearing loss, the speech sounds
became less audible and less detailed, a problem that linear amplification did not solve
properly. This demonstrated how the model could be used for hearing aid development
and evaluation.
