Fast Fourier transform analysis of the auditory brainstem response: effects of stimulus intensity and subject age, gender and test ear

The effects of subject age, gender and the test ear on auditory brainstem response (ABR) fast Fourier transform (FFT) results were examined at six stimulus intensities in 120 normal subjects. Subject age and gender, and stimulus intensity were shown to effect the ABR FFT results and must therefore be considered in any clinical ABR FFT analysis.
