Abstract
This chapter reviewed the sensory capabilities of the normal auditory system as a reference for understanding the auditory capabilities of patients with hearing impairment and their deficits in speech perception. The manner in which auditory sensations can be studied objectively was discussed, with a section on psychophysics, the measurement of sensation. The second section dealt with the auditory sensory abilities and provided a perspective for evaluation of patients with different types of hearing loss. A section on loudness the intensity, frequency, band width, and duration of the stimulating sound. The ability to discriminate between small changes in intensity was discussed. Pitch, while appearing to be the psychological quality associated with the frequency of the stimuli, may be related to the frequency of the stimulating sound. Absolute pitch judgments may not be important for daily listening, but the ability to make pitch discriminations can be very important, particularly for effective speech perception. Background noise may be a deterrent to clear auditory perception or frequency analysis. Masking was considered as the elevation in threshold of a signal by the background. The last section discussed the temporal relation between a sequence of sounds, which may be important in detection and identification of complex sounds.
