Some aspects of auditory space, speech perception and the use of hearing aids
Abstract:
The auditory space of an individual is operationally defined as that perceptual area that lies between the upper tolerance level for loud sounds and the threshold of hearing for a specified range of frequencies. Results from recent experimental work are presented to show a difference of some 15 dB between comfortable listening level and loudness discomfort-level, up to 80 dB hearing loss. Results are also shown for the measurement of reaction time to a 2AFC task testing the ability to discriminate initial consonants. Loudness scaling is suggested as a method of eliciting supra-threshold measurements which might be helpful in the fitting of hearing aids.

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
