Abstract:
OBJECTIVE To study the impacts of different noise patterns on speech perception in normal hearing subjects and patients with sensorineural hearing loss. METHODS Mandarin Hearing in Noise Test for Children was played by MATLAB software in this study. The speech intelligibility of 25 normal hearing subjects and 20 patients with sensorineural hearing loss in quiet, speech-shaped noise and two-talker babbles were tested. The differences between normal hearing subjects and patients with sensorineural hearing loss in quiet and noise conditions were analyzed. RESULTS With the decrease of signal-to-noise ratios, the speech intelligibility of normal hearing subjects in speech-shaped noise pattern was declining more severely compared with the two-talker babbles pattern but there were no significant differences between them (P＞0.05). There were significant statistical differences in speech intelligibility under quiet, speech-shaped noise and two-talker babbles at 5 dB SNR (^＜0.05) for patients with sensorineural hearing loss. And the speech recognition rate in speech-shaped noise decreased more remarkable than that in the two-talker babbles. CONCLUSION Compared two noise patterns, the accuracy of speech recognition for normal hearing subjects in two-talker babbles was higher, while the speech intelligibility was better for patients with sensorineural hearing loss in speech-shaped noise.
