Abstract:
OBJECTIVE To investigate the application value of narrow-band CE-Chirp ASSR(NB CE-Chirp ASSR)and modulated acoustic ASSR in the assessment of hearing threshold in children with hearing impairment.METHODS Forty-eight children with sensorineural hearing loss were tested by pure tone audiometry(PTA),NB CE-Chirp ASSR and modulated acoustic ASSR.According to the results of pure tone audiometry,they were divided into mild to moderate group(48 ears)and severe to profound group(48 ears).The difference and correlation between pure tone hearing threshold and ASSR response threshold of different stimuli were compared between 500-4 000 Hz.RESULTS The absolute differences between the NB CE-Chirp ASSR response threshold and the PTA threshold in 48 children were all smaller than the differences between the modulated acoustic ASSR response threshold and the PTA threshold,and the differences were statistically significant(P<0.001).Under the same stimulus sound,the absolute difference between ASSR response threshold and pure tone hearing threshold in the mild to moderate group was higher than that in the severe to very severe group.The correlation coefficients between NB CE-Chirp ASSR threshold and pure tone hearing threshold are higher than those between modulated sound ASSR threshold and pure tone hearing threshold at 500-4 000 Hz.The test time of NB CE-Chirp ASSR[(20.92±9.33)min]was significantly shorter than that of modulated acoustic ASSR[(33.68±10.97)min](P=0.004).CONCLUSION NB CE-Chirp ASSR can more accurately assess the hearing threshold of children with different degrees of hearing loss than modulated acoustic ASSR.
