Using the derived auditory brain stem response to estimate traveling wave velocity
Ear and Hearing
|April 1, 1992
Abstract:
An estimate of the traveling wave velocity (TWV) was evaluated in 18 young adults to determine the technique's applicability as a possible tool in evaluating Meniere's disease. This TWV estimation uses a derived auditory brain stem response procedure requiring high-intensity masking. The results indicate that on average, TWVs were similar to those obtained via psychophysical measures or electrocochleography. However, instances of undermasking, due to subjects' intolerance, resulted in a number of subjects exhibiting faster than expected TWVs.

01:13The Cochlea
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
01:15Auditory Pathway
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

01:21Perceiving Loudness, Pitch, and Location
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
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...
