ABSTRACT:
An improved method of gathering and analyzing auditory brainstem response (ABR) data to objectively determine the hearing capacity of an individual. The steps include generating and transmitting a plurality of hearing stimuli to the test individual and receiving the ABR signal data therefrom. The ABR signal data consists of a series of ABR waveforms, each of the waveforms being associated with a respective one of the stimuli. A concurrent replication of the ABR waveforms may be formed to indicate reliability of the data by maintaining two buffers, each of the buffers comprising ABR signal data from alternating ABR waveforms. The received ABR waveforms are analyzed to determine the hearing capacity of the individual. The analysis of the received ABR waveform may be accomplished using a computer routine incorporating new algorithms for the estimation of noise present in the ABR signal. The analysis may be further enhance by comparing the ABR signal estimate with a benchmark template formed from ABR data of good hearing subjects.
