Gender disparity in subcortical encoding of binaurally presented speech stimuli: an auditory evoked potentials study.

Objectives: To investigate the influence of gender on subcortical representation of speech acoustic parameters where simultaneously presented to both ears.

Methods: Two-channel speech-evoked auditory brainstem responses were obtained in 25 female and 23 male normal hearing young adults by using binaural presentation of the 40 ms synthetic consonant-vowel/da/, and the encoding of the fast and slow elements of speech stimuli at subcortical level were compared in the temporal and spectral domains between the sexes using independent sample, two tailed t-test.

Results: Highly detectable responses were established in both groups.
