MethodsTwenty volunteers with normal hearing level and tympanic pressure were enrolled and kept at airtight container. The inner pressure was changed to 2 kPa and 4 kPa below normal atmospheric pressure in 50 s and recovered to the normal pressure, the pure tune hearing threshold of 500, 1 000 and 2 000 Hz and tympanic pressure were measured, and acoustic impedance curve characteristic and tympanic membrane appearance were recorded at each time points.

The study also evaluates the effects of FbAANC headset on speech intelligibility on a disyllabic Mandarin word discrimination test platform. We expect someone under the noisy environment in SNR equal 0,–5,–10,-15,-20 and –25 dB, the noise cancellation technique could either improve the speech discrimination effectively. Finally, the SNR below -10dB, the mean WDT score with FbAANC headset was superior to without FbAANC headset 13 to 32% through 30 subjects of normal hearing threshold for evaluation. These results suggest that the FbAANC headset would be useful for hearing protection in workplaces with high levels industrial noise.

同时，本论文亦透过华语双字词语音辨识力测验，以评估此噪音消除技术对於语音理解力的影响，期望在SNR为0，-5，-10，-15，-20和-25dB的环境下，暸解噪音消除技术能否有效提升语音辨识力；经过30位正常听力的受测者之评估，我们可以得到当讯噪比在-10 dB以下时，经过噪音消除后的语音辨识力成绩可明显地提升13 to 32%，因此，本噪音消除耳机确实可以作为耳机防护以提供给工人对抗高分贝的工厂噪音。

The average of hearing threshold shifts at high frequencies(4k, 6k, 8kHz) is considerably larger than that at low frequencies(0.5k, 1k, 2k Hz). The moderate to severe degree of hearing loss of the paper mill workplace of subjects showed maximum notches at the frequency of 4 kHz. The noise-exposure group grades of DNA damage were significantly higher then the controls.

经扣除年龄老化因素所得到的听力损失修正值，结果显示在谈话性低频率0.5KHz、1 KHz中，女性比男性听力损失严重，并以女性、≧50岁、右耳、1 KHz 之平均值39.0±17.2dB为最高值，而於高频率2KHz至8 KHz中，不同年龄层之比较，以男性、≧50岁、右耳、8KHz之平均值49.0±27.1dB为中度至重度听力损失情形。

It is important that people using hearing aids continue to receive advice and support about assistive hearing devices after they receive their aids, to ensure that their specific needs are being met.

这是非常重要的人使用助听器继续接受咨询和支持有关辅助听觉装置后，他们收到他们的艾滋病，以确保他们的具体需要得到满足。

Objective To explore the prediction of bone-conduction of audiometric threshold in normal-hearing adults using multiple auditory steady-state response. Methods BC-ASSR and BC-A were recorded in 20 normal-hearing adults(10 males and 10 females). The response thresholds and the behavioral thresholds were compared at 0.5, 1.0, 2.0 and 4.0kHz to get the correlation and regression formulae.

目的 探讨多频听性稳态反应评估听力正常青年人骨导纯音听阈的可能性，旨在观察听力正常青年人骨导多频听觉稳态反应测试的正常值特点，进一步探讨骨导ASSR的反应阈与骨导纯音听阈的相关性，为临床上对不能配合做纯音测听的患者行听力评估时提供客观参考。

Objective: To discover the hearing disorder and its related factors in neonatus by evaluating the detective rate of distortion product otoacoustic emissions in hearing screening in Tanggu district of Tianjin.

Objective:to probe the application on the hearing screening of the neonatus by transcience otoacoustic emission.methods: to undertakethe hearing screening of the neonatus by transcience otoacoustic emission of 2 100 neonatus from 2006.1~2006.12.results: 2 058 (98.4%) full-term newborn infants pass the transience otoacoustic emission once and 33(1.6%) full-term newborn infants can not pass it once.9(77.8%) premature infants pass the transience otoacoustic emission once and 2 premature infants can not pass it once.conclusion: the transience otoacoustic emission is worth to application because it has non-wound, fast, objective merit.

目的：探讨观察瞬态耳声发射在新生儿听力筛查中的应用。方法：对2006年1月~2006年12月2 100例新生儿利用瞬态耳声发射进行听力筛查的资料进行分析。结果：2 091例足月新生儿中，一次通过瞬态耳声发射进行听力筛查 2 058例，占98.4%，未通过33例，占1.6%，早产儿9例中，一次通过检测7例，占77.8%，未通过2例，占22.2%。全部未通过新生儿检查abr，确诊有异常15例，正常7例。结论：瞬态耳声发射具有无创伤、快速、客观、敏感度高等优点，值得在新生儿听力筛查中广泛推广应用。

But a number of defects and deficiencies exist yet in our country"s present administrative hearing system compared to western countries, such as the lack of transparency, the nondependent legal status of the host, the ambiguity of record and the faultiness of the system itself, because it was not a long time since introduced from foreign countries. And how to use the western countries" experiences for reference and integrate our practicality is very significant, in order to develop and perfect our countrys administrative hearing.
