Using the derived auditory brain stem response to estimate traveling wave velocity.
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.
