Summary
Bilateral Contralateral routing of Signal (BICROS) hearing aids significantly improved speech perception in noise for individuals with asymmetric hearing loss compared to monaural aids.
Area of Science:
- Audiology
- Hearing Aid Technology
- Speech Perception
Background:
- Asymmetric hearing impairment presents unique challenges for speech understanding.
- Conventional monaural amplification may not adequately address the needs of these individuals.
- Bilateral Contralateral routing of Signal (BICROS) hearing aids offer a potential solution for complex hearing loss.
Purpose of the Study:
- To evaluate the effectiveness of BICROS hearing aids in improving speech perception in noise for asymmetrically hearing-impaired subjects.
- To compare the performance of BICROS aids against conventional monaural amplification.
Main Methods:
- 14 subjects with asymmetric hearing impairment participated.
- Speech Perception in Noise (SPIN) and Synthetic Sentence Identification (SSI) tests were administered.
- Tests were conducted with both monaural amplification and BICROS hearing aids in a four-talker babble noise background.
Main Results:
- Subjects demonstrated significantly better speech perception in noise when using BICROS hearing aids.
- Performance with BICROS aids surpassed that achieved with monaural amplification alone.
Conclusions:
- BICROS hearing aids are an effective intervention for enhancing speech perception in noise in individuals with asymmetric hearing loss.
- This technology offers a substantial benefit over traditional monaural amplification for this population.
