Background:

  • Auditory Brainstem Responses (ABRs) are crucial for assessing auditory pathway function.
  • Automatic detection of ABR peaks simplifies clinical analysis.
  • Existing methods may lack accuracy or require manual intervention.

Purpose of the Study:

  • To develop and validate an automated system for detecting auditory brainstem responses (ABRs).
  • To accurately identify the pedestal peak and subsequent Peak V in filtered ABR signals.
  • To achieve high accuracy in ABR peak detection using clinical data.

Main Methods:

  • A multistage automatic peak detection process was implemented.
  • The system focuses on identifying the pedestal peak within the ABR signal.
