ABSTRACT |
Purpose: Although many previous studies related to sentence recognition of the hearing-impaired elderly have found their poor performance under various distracting listening conditions, there is still a lack of information for their error type in the sentence. The purpose of present study was to analyze a prominent error type among nine parts of speech in various levels of noise and fast speech conditions for the hearing-impaired elderly. Method: Seven old listeners with moderate sensorineural hearing loss participated. For estimating their sentence recognition, Korean Speech Perception in Noise was applied for four signal-to-noise ratios (no noise, +6, +3, 0 dB) and four time alteration conditions (±30%, ±15%), while being presented at the most comfortable level to each participant. Total percent error and substitution error patterns of the sentence recognition were analyzed as a function of conditions. Results: The percent error of sentence recognition was increased as either noise level increased or speech rate was faster. Among the parts of speech, noun substitution error pattern showed the highest number for all participants regardless levels of noise and time alteration. Interestingly, the noun substitution error pattern was outstood in quiet and 15% time compression. Conclusion: Results of the present study suggest that aural rehabilitation of the hearing-impaired elderly may focus on reducing and correcting the noun substitution error to improve their sentence recognition. |
