Abstract EN
Background.
The aim of this study was to investigate the individual effects of envelope enhancement and high-pass filtering (500 Hz) on word identification scores in quiet for individuals with Auditory Neuropathy.
Method.
Twelve individuals with Auditory Neuropathy (six males and six females) with ages ranging from 12 to 40 years participated in the study.
Word identification was assessed using bi-syllabic words in each of three speech processing conditions: unprocessed, envelope-enhanced, and high-pass filtered.
All signal processing was carried out using MATLAB-7.
Results.
Word identification scores showed a mean improvement of 18% with envelope enhanced versus unprocessed speech.
No significant improvement was observed with high-pass filtered versus unprocessed speech.
Conclusion.
These results suggest that the compression/expansion signal processing strategy enhances speech identification scores—at least for mild and moderately impaired individuals with AN.
In contrast, simple high-pass filtering (i.e., eliminating the low-frequency content of the signal) does not improve speech perception in quiet for individuals with Auditory Neuropathy.
