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.

助听器的客观评估：放大语音的可听性，听力受损的人可以通过戴上助听器来听到多少言语？根据语音歧视测试或带有助听器的单词识别测试的结果，我们可以间接地知道他或她对言语的可听性。这项研究的目的是使用探针管麦克风来量化一个加热受损的人的放大语音的可听性。在研究中，我们使用了非线性助听器。报告了我们测量的水平分布和动态语音的动态范围的结果。助听器的主体评估：听力受损对助听器的自我评估，一份24个项目的自我管理问卷调查表，量化了日常生活中听力辅助用量化的绩效。概况在三种不同的听力情况下（嘈杂，回响和安静的环境）以及对放大环境声音的反应来评估语音的扩增经验。还使用问卷调查了满意度。该问卷是向82位经验丰富的助听器用户管理的。结果表明，有6％的受试者对助听器感到满意，41％的受试者不满意，其余53％是中间的。在不同程度满意度的受试者的自我评估表现评分之间存在显着差异。对于不同听力环境的自我评估表现得分之间也观察到了显着差异。总的来说，受试者在安静的情况下和听取环境声音的助听器方面的成功率要大得多，而不是在嘈杂和混响的情况下。在文本中讨论了有关放大效果，与听力水平的关系，与听力水平的关系，有效性和模拟个人助听器的局限性的个体差异。
