查询词典 loss of hearing

Objective To develop a kind of preliminary screening acoumeter for the prevention of noise-induced hearing loss. Methods This portable preliminary screening acoumeter based on ARM7 LPC2148+SD card+VS1003 can make anti-noise hearing protection.

目的 研制强噪声引起听力损伤预防和快速初筛仪，能预防强噪声给人员带来的听力损伤，并能实施听力损伤的快速筛查。

A pure tone audiogram identified severe bilateral symmetric down-sloping sensorineural hearing loss with otherwise normal caloric testing result. Bilateral optic fundus examination using fluorescein angiography identified retinitis pigmentosa. A diagnosis of Usher syndrome Type Ⅱ was diagnosed based on these findings. The patient has worn a hearing aid with reasonable success, and has been advised to eat green vegetables and fruit to minimize further visual impairment.

纯音听力检查两耳为对称性重度感觉神经性听力障碍，视野检查为周边视野缺损，眼底血管萤光摄影显示色素变性，前庭功能检查正常，经诊断为Usher症候群第二型，目前患者配戴助听器后生活与人沟通尚无大碍、唯视障只能建议其多摄取叶绿蔬果（叶绿素、叶黄素、维他命A等）及眼睛防晒来防止恶化。

Objective To study the correlation between the thresholds of auditory steady-state evoked response and those of pure tone audiometry in ears with hearing loss to guide the impersonal hearing evaluation.

目的 研究不同听力损失耳的听觉稳态诱发反应(auditory steady-state evoked response， ASSR)与纯音听阈的关系，为客观的听力评估提供指导。

While sign language and lip reading are very important and often of invaluable help to many people suffering from hearing loss, they aren't always the solution because not everybody knows sign language and some hearing impaired people have not got the skills to lip read.

虽然手语和唇读是非常重要的，往往是宝贵的帮助许多人患有听力丧失，它们并非总是的解决办法，因为不是每个人都知道手语和一些听力受损的人没有得到的技能，以唇读。

Results The resonant frequency of low frequency conductive hearing loss and normal hearing group were different.

结果 传导性低频听力损失组的中耳共振频率与听力正常组有统计学差异。

Results The resonant frequencies of low conductive frequency hearing loss and normal hearing groups were different.

结果传导性听力损失和听力正常组的共振频率来自不同的总体。

Methods One hundred and twenty cases (165 ears) of tinnitus and/or hearing loss were differentiated into five syndrome patterns according to the theory of traditional Chinese medicine: invasion of wind-heat, liver-fire up-stirring, stagnation of phlegm-fire, kidney-essence deficiency and weakness of spleen-stomach. Hearing threshold of pure-tone, function test above hearing threshold and matching of tinnitus frequency and loudness were carried out in all cases and the data were analyzed by SPSS statistical software.

方法］选择具有典型中医证候表现的耳鸣耳聋患者120例（165耳），经传统方法辨证为风热侵袭、肝火上扰、痰火郁结、脾胃虚弱、肾精亏损5个证型，分别进行纯音听阈测试、阈上功能测试、耳鸣频率及响度匹配，数据经SPSS软件进行统计学处理。

BACKGROUND: In recent years, great advances have been made in human genetics. Many genes responsible for syndromic or non-syndromic hearing loss have been mapped. It was reported that the mutation of PDS gene causes classic Pendred syndrome as well as non-syndromic hearing loss.

背景：近年来，国外在人类基因的研究上突飞猛进，已经找到很多引起症候群或非症候群听障的基因，而已知PDS基因的突变，会引起Pendred症候群或非症候群听障（DFNB4）。

Their speech and language skills will be variably affected depending upon when the hearing loss was sustained, that is in childhood or adulthood, the degree and nature of the hearing loss, and the effectiveness of subsequent therapeutic programs.

他们的说话能力和语言文字能力会会有不同的影响，这取决于：他们何时受到听力损害-在孩提时还是成年时，听力损失的程度和性质，以及后继治疗过程的有效性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
