Summary
Brainstem evoked response audiometry (BERA) shows a reliable correlation with biological hearing thresholds in adults. This study suggests correction factors for BERA to improve hearing threshold assessment accuracy.
Area of Science:
- Audiology
- Neuroscience
- Electrophysiology
Context:
- Objective hearing evaluation is crucial for auditory rehabilitation, especially in infants and young children where traditional audiometry is not feasible.
- Electrophysiological methods like Brainstem Auditory Evoked Potentials (BAEP) and acoustic stapedius reflex are used for objective hearing threshold assessment in this age group.
Purpose:
- To analyze the correlation between biological hearing threshold determined by tonal audiometry and objective measures using ipsilateral stapedius reflex and Brainstem Evoked Response Audiometry (BERA).
Summary:
- A statistically significant correlation was found between biological hearing threshold and BERA response threshold across various frequencies (500 Hz to 4,000 Hz).
- The correlation between biological hearing threshold and ipsilateral stapedius reflex threshold was less consistent, showing significance only at 4,000 Hz.
Impact:
- The findings support the reliability of BERA for objective hearing threshold evaluation.
- This study proposes correction factors for BERA to enhance the accuracy of biological hearing threshold assessment, despite acknowledging its limitations.
