如何分析聋生的听力损失情况

不是问听力损失情况的分级 我是问会出什么形式的题目来让你分析聋生的听了损失情况 会不会是出一个听力图之类的？

Answer 1

正常听力 -10-25分贝 对一般的声音及语言分析清楚
轻度听力损失 26-40分贝 对细小的声音难以分辨，如树木风吹声
中度听力损失 41-55分贝 对日常语言有听觉上的困难，与人交谈感到扫地清，开始需要借助助听器的帮助
中重度听力损失 56-70分贝 对于较大的谈话声、汽车声仍感到模糊，助听器帮助较大
重度听力损失 71-90分贝 对于叫喊声音及洪亮的声音如喇叭声、鼓声才有反应，助听器帮助较大
极重度听力损失 90分贝以上 通常极难感觉声音的存在，需要靠助听器辅助，才能感受声音的震动力

Pure tone audiometry (PTA) is the key hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss. Thus, providing the basis for diagnosis and management. PTA is a subjective, behavioural measurement of hearing threshold, as it relies on patient response to pure tone stimuli. Therefore, PTA is used on adults and children old enough to cooperate with the test procedure.

There are three types of hearing loss:
Conductive - Usually caused by things like wax in the ears. This is one of the easiest types to treat.
Sensorineural - Involves the inner ear or the nerve cells. Can be treated with hearing aids or cochlear implants in most cases.
Mixed - Both a conductive and a sensorineural loss.
Children with ear infections often experience conductive hearing loss from the buildup of fluid in their ears. Older people may experience a sensorineural hearing loss.

Degrees of Hearing Loss
Determining the degree of hearing loss can be difficult, particularly with young children who do not test as well as older people who can provide more accurate results.

There are basically four degrees :
Mild - At 26-45 db, a little difficulty hearing speech. Even a mild hearing loss can be serious for children still learning to talk.
Moderate - At 46-65 db, more difficulty hearing speech.
Severe - At 66-85 db, a lot of difficulty hearing speech. It is at this level that we begin to use the term "deaf."
Profound - Anything over 85 db. With this level of hearing loss, hearing aids may or may not help; cochlear implants are often an option.

有专业的评估方式 相关医院能够提供此类服务
大致情况 会在专门的隔音房间内 让受试者遮挡住一侧耳朵 然后播放一定分贝级别的 不固定内容 之后让受试者复述 一般分贝数由低到高 逐渐提升 直至可听见并完整复述为止 然后测试另一侧耳朵 通过这个就能大致判断听力
