Objective To analyze the clinical characteristics of patients with presbycusis by using disyllabic mandarin speech test materials (MSTMs).Methods A total of 59 subjects (23 men and 36 women) with presbycusis,from 61 to 84 years old with the average as 71.3±6.7.They were divided into three groups:the mild group (10 subjects),the moderate group (35 subjects)and the severe group (14 subjects)according to the pure tone average (PTA) thresholds at 0.5,1,2 and 4 kHz from the better ear.In addition,11 subjects of elderly persons with normal hearing were used as the control group.All the subjects enrolled in this study could speak Mandarin well in their daily lives.Nine lists of disyllabic mandarin speech test materials were utilized to test speech recognition threshold (SRT) and P-I function for these groups respectively.Results The PTA(51.65±11.98)and SRT (50.98±16.05)from presbycusis group were much higher than the control group(PTA 19.55± 4.55,SRT 18.79± 7.45),while the average slope of the P-I function 2.63％/dB from the presbycusis group was lower than the control group 4.65％/dB (P＜0.01).The SRT of male patients (56.54±17.23) was higher than the females(47.99± 15.63) (P＜0.05).The PTA and SRT in these three groups divided by degrees of hearing loss were higher than the control group obviously.The PTA and SRT had significantly increased as the degree of hearing loss increased.The differences among these groups were significant (P＜0.01).The average slope of P-I function of these three groups divided by degrees of hearing loss (mild group:2.47％/dB,moderate group:2.76％/dB,severe group:2.42％/dB) was smaller than the slopes in the control group which was 4.65 ％/dB (P＜0.01).The average slope of P-I function among these groups had no significant difference (P＞0.05).Conclusion The SRT of patients with presbycusis increased and the SRT of male was higher than the females.The average slope of P-I function decreased and the curve moved to right side and became a gradual curve.As hearing loss became more severe,the SRT rose more apparently.

Journal of Audiology and Speech Pathology.2017;25(6):640-644. doi:10.3969/j.issn.1006-7299.2017.06.021

Objective To investigate the effects of nonlinear frequency compression (NLFC) on sound quality perception by the Mandarin-speaking subjects with high-frequency hearing loss.Methods Twenty-three listeners with sensorineural hearing loss with no previous experiences of using hearing aids participated in this study.They were all fitted binaurally with Phonak Bolero Q hearing aids.The stimuli,including male voice,female voice,bird chirping,music,and self-voice,were presented in a random order with a custom software via a loudspeaker at 65 dB SPL.Regarding NLFC parameters,cut-off frequency (CF) ranged from 4.9 to 6 kHz and compression ratio (CR) was programed as 1.5.Subjects evaluated the sound quality of the stimulus in loudness,clearness,naturalness and overall preference under the conditions of NLFC-on and NLFC-off.A paired-sample t-test was conducted to assess the group differences in sound quality rating between NLFC on and off conditions.Results Paired test showed significant difference of high-frequency hearing threshold under the condition of NLFC-on and NLFC-off at 6 and 8 kHz(P＞0.05).No significant statistical difference was found in subjects' sound quality ratings between NLFC-on and NLFC-off conditions (all P＞0.05).Conclusion NLFC technology resulted in no significant impact on sound quality perception for the non-experienced hearing aid users.
