Derived cochlear nerve and brainstem evoked responses of the human auditory system. The effect of masking in the derived band.
Derived cochlear nerve and brainstem evoked responses (CBER) were obtained for various frequency bands and were masked using special maskers. These maskers were designed to match exactly the intensity/frequency profile characteristics of the bands from which derived CBERs were obtained. Derived responses were markedly affected whenever the masker frequency limits coincided with the corresponding derived band. Other derived responses from adjacent bands were not affected. Since adjacent derived bands overlap, these overlapping regions were not considered to be represented in the derived responses. Therefore the actual frequency regions which the derived responses represented were considered to be smaller than the derived bands calculated from the physical parameters of the high-pass masking noises.
