Real-time threshold determination of auditory brainstem responses by cross-correlation analysis
Summary: Auditory brainstem response (ABR) serves as an objective indication of auditory perception at a given sound level and is nowadays widely used in hearing function assessment. Despite efforts for automation over decades, ABR threshold determination by machine algorithms remains unreliable and...

The threshold level was then indicated by a dramatic increase in the sweep numbers required to produce “qualified” level averaging.
