为对托幼机构的儿童听力现状有所了解,并早期发现听力障碍儿,早期干预,我所耳保健科于1993年4月～7月对3个城区(东城、崇文、宣武)5个园所的儿童进行了听力筛查。1 资料与方法1.1 筛查对象托儿所、幼儿园2～6岁儿童。其中男376人.女288人;2～4岁282人,4～6岁382人。1.2 方法(1)使用协和招商听力康复部研制的行为测听仪,借鉴古典的游戏测听法。(2)选择较安静的房间,周围墙壁无镜子。(3)测查前通过保健医或老师向小儿说明测查方法。小儿进入房间后,检查者向其示范。(4)受检儿童前面放置一教学用的拨珠器,嘱个儿听见声音后拨1颗珠子。1 名测查人员在小儿身后距小儿耳朵10～15cm处给声刺激,让小儿熟悉声源,然后用30dB声压级分别以500Hz、1000Hz、2000Hz逐一测试,每个频率给声3次,如某一频率未通过进行复测,仍未通过者做为听力障碍可疑者转我所耳保健门诊进一步检查。根据幼儿不同年龄分别作行为测听、纯音、声阻抗及ABR测听。
In order to understand the current situation of children’s hearing in kindergartens and nurses, early detection of hearing-impaired children and early intervention was conducted in five health parks in three districts (Dongcheng, Chongwen and Xuanwu) from April to July 1993, The children had hearing screening. 1 Materials and Methods 1.1 screening objects nurseries, kindergartens 2 to 6-year-old children. Among them, 376 are male, 288 are female, 282 are 2-4 years old, 382 are 4-6 years old. 1.2 Methods (1) The use of Concord Investment Hearing and Rehabilitation Department developed behavioral audiometer, learn from the classical game audition method. (2) choose a quieter room, no walls around the mirror. (3) before the test through the health doctor or teacher to explain the test method to children. Children enter the room, the examiner to demonstrate. (4) Children in front of the test to place a teaching of the use of beads, Zhu Er heard a child after hearing a bead. An investigator in the pediatric children behind the ears from 10 ~ 15cm to stimulate the sound, so that children familiar with the sound source, and then with 30dB SPL respectively 500Hz, 1000Hz, 2000Hz one by one test, each frequency to the sound three times, such as A certain frequency did not pass the re-test, still not passed as a suspicious hearing-impaired people go to my ear health clinic for further examination. Behavioral audiometry, pure tone, acoustic impedance and ABR audiometry were performed according to different ages of children.
