项目摘要

Objective Evaluation of Hearing aids : Audibility of Amplified Speech, How much can a hearing-impaired person hear amplified speech by wearing a hearing aid? From results of a speech discrimination test or a word identification test with a hearing aid, we can indirectly know his or her audibility of amplified speech. The purpose of this study is to quantify audibility of amplified speech for one heating-impaired person using a probe tube microphone. In the study we used a non-linear hearing aid. The results in which we measured level distribution and dynamic range of amplified speech are reported.Subjective Evaluation of Hearing Aids : Self-assessment of hearing aids by the hearing impaired, A 24-item self-administered questionnaire that quantifies performance with a hearing aid in everyday life was developed. The profiles assess experience with amplification of speech in three different listening situations (noisy, reverberant, and quiet environments) and in terms of reactions to amplified environmental sounds. Satisfaction was also assessed using the questionnaire. The questionnaire was administered to 82 experienced hearing aid users. Results revealed that 6% of the subjects were satisfied with their hearing aids, 41% of the subjects were dissatisfied and the remaining 53% were intermediate. There were significant differences between the self-assessment performance scores of subjects with different degree of satisfaction. Significant differences were also observed between the self-assessment performance scores for different listening environments. In general, subjects reported significantly more success with their hearing aids in quiet situation and in listening to environmental sounds than in noisy and reverberant situations. Individual differences with respect to amplifications effects, relationship to hearing level, effectiveness and limitation of analog personal hearing aids are discussed in the text.

助听器的客观评价：放大语音的可听度，听障人士佩戴助听器能听到多大程度的放大语音？从言语辨别测试或助听器单词识别测试的结果中，我们可以间接知道他或她对放大语音的可听度。本研究的目的是量化一名患有热病的人使用探管麦克风放大语音的可听度。在研究中我们使用了非线性助听器。报告了我们测量放大语音的电平分布和动态范围的结果。助听器的主观评估：听力受损者对助听器的自我评估，开发了一份包含 24 项的自填问卷，用于量化助听器在日常生活中的表现。这些配置文件评估了在三种不同聆听环境（嘈杂、混响和安静环境）下的语音放大体验以及对放大的环境声音的反应。还使用问卷评估了满意度。该问卷调查对象为 82 名有经验的助听器使用者。结果显示，6% 的受试者对他们的助听器感到满意，41% 的受试者不满意，其余 53% 的受试者处于中等水平。不同满意度的受试者的自评表现得分存在显着差异。不同聆听环境的自我评估表现分数之间也观察到显着差异。一般来说，受试者报告在安静的情况下和聆听环境声音时使用助听器的成功率明显高于在嘈杂和混响的情况下。文中讨论了模拟个人助听器的放大效果、与听力水平的关系、有效性和局限性方面的个体差异。
