Journal of Rehabilitation Research and Development
|January 1, 1986
Summary
FM auditory trainers significantly improve speech perception in noise and reverberation. FM transmission offers a clear advantage for speech intelligibility, regardless of the specific device used.
Area of Science:
- Audiology
- Speech-Language Pathology
- Acoustics
Background:
- Auditory trainers are crucial for individuals with hearing impairments.
- Noise and reverberation pose significant challenges to speech perception.
- Understanding the performance of different transmission modes is essential.
Purpose of the Study:
- To evaluate speech perception using FM auditory trainers.
- To assess the impact of noise and reverberation on auditory trainer performance.
- To compare different transmission modes in commercially available units.
Main Methods:
- Speech perception tests were conducted using FM auditory trainers.
- Conditions included varying levels of noise and reverberation.
- Performance was analyzed across different commercially available FM units.
Main Results:
- FM transmission demonstrated a substantial benefit for speech intelligibility.
- This advantage was consistent across various listening conditions.
- Individual instrument capabilities did not negate the FM transmission benefit.
Conclusions:
- FM auditory trainers provide superior speech perception in challenging acoustic environments.
- FM transmission is highly effective in mitigating the negative effects of noise and reverberation.
- The findings support the use of FM systems for enhanced auditory rehabilitation.
