Purpose:

  • To evaluate the efficacy of wavelet transform in analyzing human ABR signals.
  • To compare the precision of wavelet transform with conventional methods for ABR analysis.
  • To determine the optimal wavelet transform scale for human ABR.

Summary:

  • Human ABR signals from normal hearing and sensorineural hearing loss groups were analyzed using wavelet transform.
  • Wavelet transform at scale 3 proved adequate for human ABR analysis.
