【摘要】：目的探討非線性頻率壓縮(nonlinear frequency compression,NLFC)助聽器對以漢語普通話為母語的耳聾患者噪聲下言語識別的影響,為耳聾患者助聽器選配及助聽效果評估提供參考。方法 25例以漢語普通話為母語的感音神經(jīng)性聾患者,均雙耳佩戴助聽器,根據(jù)患者是否有NLFC助聽經(jīng)驗分為A、B兩組:A組13例有NLFC助聽經(jīng)驗,日常使用NLFC技術(shù);B組12例無NLFC助聽經(jīng)驗,日常使用傳統(tǒng)放大(conventional process,CP)技術(shù)。所有患者分別在NLFC和CP條件下進行噪聲下句子識別測試,比較其結(jié)果。結(jié)果 A組患者在NLFC和CP條件下的噪聲下言語識別率分別為82.33%±16.06%、76.70%±18.08%,前者高于后者,差異有顯著統(tǒng)計學(xué)意義(P0.01);B組分別為83.04%±12.56%、81.79%±20.07%(P=0.19),差異無統(tǒng)計學(xué)意義。A組患者在NLFC和CP條件下的高頻(4、6、8kHz)助聽聽閾分別為53.54±7.30、57.01±6.81dB SPL,B組分別為57.42±8.38和61.21±7.42dB SPL,兩組NLFC條件下的助聽聽閾低于CP條件,差異均有統(tǒng)計學(xué)意義(P0.01)。經(jīng)統(tǒng)計學(xué)回歸處理,患者在NLFC和CP條件下的高頻助聽聽閾差值與言語識別率差值呈線性相關(guān)(r=0.63,t=3.89,P=0.007)。結(jié)論 NLFC技術(shù)可改善患者高頻可聽度及噪聲下言語識別,一定的NLFC使用經(jīng)驗可使NLFC助聽效果最大化。
[Abstract]:Objective to investigate the effect of nonlinear frequency compression (nonlinear frequency compression,NLFC (nonlinear frequency compression,NLFC) hearing aid on speech recognition under noise in deafness patients using Mandarin Chinese as their mother tongue, so as to provide reference for hearing aid selection and evaluation of hearing aid effect in deafness patients. Methods Twenty-five patients with sensorineural hearing loss, whose mother tongue was Mandarin Chinese, wore hearing aids in both ears. According to whether the patients had NLFC hearing aid experience, they were divided into two groups: group A and group A (n = 13) with NLFC hearing aid. NLFC technique was used in group B (12 cases without NLFC hearing aid) and conventional amplification (conventional process,CP) technique. All patients were tested for sentence recognition under noise under NLFC and CP, and the results were compared. Results the speech recognition rates of group A under NLFC and CP were 82.33% 鹵16.06% 鹵76.70% 鹵18.08, respectively. The former was higher than the latter. There was significant difference between group B (P0.01) and group B (83.04% 鹵12.56% 鹵81.79% 鹵20.07% (P0. 19), respectively. There was no significant difference between group A and group A. the hearing threshold of group A was 53.54 鹵7.3057.01 鹵6.81dB SPL,B, 57.42 鹵8.38 and 61.21 鹵7.42dB SPL, respectively, lower than that of CP under NLFC and CP. The difference was statistically significant (P0.01). By statistical regression analysis, the difference between the hearing threshold of high frequency hearing aid and the speech recognition rate was linearly correlated with the difference between the hearing threshold and the speech recognition rate in NLFC and CP (r = 0.63t = 3.89 P0. 007). Conclusion NLFC technique can improve the high frequency audibility and speech recognition of patients under noise. A certain experience of NLFC use can maximize the effect of NLFC hearing aid.
