【摘要】：目的通过比较双侧中重度听力损失患者在单、双耳助听下的可接受噪声级(acceptable noise level,ANL),探讨ANL对助听器验配及预测助听效果的作用。方法选取15例双侧中重度听力损失患者,分别测得双耳未助听、左耳助听、右耳助听和双耳助听状态下的最舒适响度级(most comfortable levels,MCL)、最大背景噪声级(background noise level,BNL),并计算得到ANL值(ANL=MCL-BNL),对结果进行统计学分析。结果 15例受试者双耳未助听、左耳助听、右耳助听及双耳助听四种状态下测得的ANL值分别为18.87±5.26、12.60±2.47、12.00±2.90、5.13±1.25dB S/N;MCL值分别为80.40±9.28、63.73±5.15、62.27±5.36、61.80±6.05dB HL;BNL值分别为61.67±6.14、51.13±3.94、50.27±4.50、56.67±5.16dB HL;左耳助听与右耳助听下的ANL值差异无统计学意义(P0.05);单、双耳助听下与未助听的ANL值差异均具有统计学意义(P0.05);双耳助听状态下ANL值显著低于单耳助听(P0.05)。结论 ANL值较低耳更利于助听器验配,佩戴助听器能有效提高听障患者对噪声的接受能力,并且双耳佩戴助听器的效果明显优于单耳。
[Abstract]:Objective to investigate the effect of ANL on hearing aids in patients with moderate and severe hearing loss by comparing the acceptable noise level of noise level and ANLL in patients with moderate and severe hearing loss under unilateral and biaural hearing aids.Methods Fifteen patients with bilateral moderate and severe hearing loss were selected and measured.Under the condition of right ear hearing aid and binaural hearing aid, most comfortable level mCLs of the most comfortable loudness level and the background noise level of the maximum background noise level were obtained. The ANL values were calculated and the results were analyzed statistically.Results 15 subjects had no hearing aid in both ears and left ear.The ANL values of right ear hearing aid and binaural hearing aid were 18.87 卤5.2612.60 卤2.4712.00 卤2.90 卤5.13 卤1.25dB S / NL, respectively 80.40 卤9.28o63.73 卤5.1552.27 卤5.362.27 卤5.361.80 卤6.05dB HLBNL were 61.67 卤6.1451.13 卤3.940.27 卤4.50,56.67 卤5.16dB, respectively, there was no significant difference between left ear hearing aid and right ear hearing aid in ANL value (P 0.05).There were significant differences in the ANL values between the two ears and the unassisted ones (P 0.05), and the ANL value in the binaural hearing aids was significantly lower than that in the monaural hearing aids (P 0.05).Conclusion the ANL value is more favorable for hearing aid matching, and hearing aid can effectively improve the ability of hearing impaired patients to accept noise, and the effect of binaural hearing aid is obviously better than that of single ear.
