听力

To suggest that they should take a rest after using the earphones for a long time, reduce smoking and drinking, take audiometric tests to protect their healthy.

建议播音员在长时间佩带耳机后应适当休息、减少抽菸及喝酒量并定期实施听力检查，以保护广播业劳工的健康。

Objective To calculate the least acoustic response value of children aged 0-6 years in a quiet room, and to explore the positive standards of hearing screening at different ages in some nonstandard audiometric room.

目的计算0-6岁儿童在相对安静房间(本底噪声≤45dB A)测听的最小听觉反应值，探讨在非标准测听室进行儿童听力筛查不同年龄组的筛查阳性标准。

Results The effectiveness of treating sudden deafness was closely associated with the onset time of disease and treatment in early times and associated with the degree of hearing loss ,however ,not with the age ,gender ,vertigo and tinnitus、the types of the audiometric results、hypertension or diabetes.

结果：突发性聋的疗效与年龄、性别、单、双耳发病、是否伴有眩晕和耳鸣、是否伴有高血压、是否伴有糖尿病、听力曲线类型及住院治疗时间无关，而与发病到初治的时间、治疗前耳聋程度有显著的相关性。

ABR, a highly useful clinical procedure as behavioral audiometric procedure are not sutiable, inconclusive.

ABR使用的普遍性与行为听力学相同，但其无法像行为听力学一般能代表500-8000Hz的听力。

The follow up audiometric measurement（the average hearing threshold at 0.5, 1.0, 2.0 kHz HL） was taken.

计算语言频率（0.5，1， 2 kHz）气导平均听力及气骨导差，比较不同手术方式和PORP植入方式对疗效的影响。

Pre-operative audiometric testing revealed a mean air conduction pure tone average of 51.93 dB and a mean bone conduction PTA of 23.17 dB.

目的 探讨用耳后带蒂肌筋膜骨瓣修复听骨链在听力重建手术中的应用。

Pre-operative audiometric testing revealed a mean air conduction pure tone average of 51.93 dB and a mean bone conduction PTA of 23.17 dB. The mean post- operative air conduction and bone conduction PTA were 36.59 dB and 24.23 dB, respectively.

术前临床测试平均气导51.93 dB，平均骨导23.17 dB；术后平均气导36.59 dB，平均骨导24.23 dB，术前、术后骨气导差距分别为28.76 dB和12.36 dB，骨气导差距改善了16.40 dB，68%的病人骨气导差距缩小到20 dB以内，无听力下降者。

Pre-operative audiometric testing revealed a mean air conduction pure tone average of 51.93 dB and a mean bone conduction PTA of 23.17 dB. The mean post- operative air conduction and bone conduction PTA were 36.59 dB and 24.23 dB, respectively. The mean pre- and post- operetive air-bone gaps were 28.76 dB and 12.36 dB, respectively, with a gain of 16.50 dB. Sixty-eight percent of patients closed their ABGs to within 20 dB.

Child cerebral form is the most common form of ALD.Its main clinical characteristics are mental impairment,limbs weakness,alalia,ataxia,seizures,viral and auditive disturbances.Some patients accompanied by visaul nerve atrophy,adrenal cortex and testicle impairment.ALD can be diagnosed by clinical characteristics combined with cerebral MRI.

结论ALD以儿童脑型常见，主要表现为智能下降、肢体无力、言语不清、共济失调、视听力下降及癫发作等症状，可伴有视神经萎缩、肾上腺皮质及睾丸损害，依据临床症状和典型的MRI表现可以进行临床诊断。
