Cochlear travelling wave velocities calculated from the derived components of the cochlear nerve and brainstem evoked responses of the human auditory system.
From the latency difference between corresponding components of the different derived cochlear nerve and brainstem evoked responses (CBER) and the cochlear location difference between the appropriate derived band centre frequencies (CF), estimates of the travelling wave velocity at various locations along the cochlear partition were calculated. Calculated velocities compared favourably with velocity data obtained using widely contrasting techniques. Derived CBER waveforms were therefore considered to truly represent neural activity initiated by activity at specific frequency regions along the cochlear partition.
