人类在进化与适应外界环境的过程中,形成了特殊的感觉器官,这些感觉器官包括听觉、视觉、皮肤触觉、嗅觉及其他分析器。听分析器在整个机体及大脑活动中起着重要的作用,声音经传导到听分析器的末端柯替氏器官,再经过听神经传导达到大脑皮层听区,又进行细致的分析综合,于是我们感到声音。听力减退或失去听力在某些方面会影响劳动力。在许多职业中,如汽车司机、飞行员、电话员、电报员等,没有好的听力是不能胜任的。于是听力检查成为耳鼻咽喉科医师的日常工作。进行听力检查的目的,在于测定听力是否正常,如果听力减退,还需测定听力减退的程度及听力障碍的种类。而且听力检查对耳疾之诊断、预后、治疗及聋的预防关系至巨。
In the process of evolution and adaptation to the external environment, humans form special sensory organs, which include auditory, visual, skin touch, olfactory and other analyzers. Listen to the analyzer throughout the body and brain activity plays an important role, the sound is guided to listen to the end of the analyzer Cochrane organ, and then through the auditory nerve conduction to the auditory cortex, and careful analysis of synthesis, so we feel sound. Deafness or loss of hearing can in some ways affect the workforce. In many occupations, such as car drivers, pilots, telephones, telephones, etc., good listening is not possible. Hearing tests then become an otolaryngologist’s daily routine. The purpose of hearing tests is to determine the hearing is normal, if the hearing loss, but also to determine the degree of hearing loss and the type of hearing loss. And hearing tests on otology diagnosis, prognosis, treatment and prevention of deaf to the giant.
