家用电器噪音 Household appliances noise

　　不亚于交通、施工噪音 As the traffic/Construction noise

　　本报讯(记者刘璇 通讯员杨璠)今天是第十四个全国爱耳日，来自武大人民医院听力门诊的调查发现，五成听力损伤并非严重的噪音造成，而是潜伏在身边不以为然的“小噪音”引起的慢性损伤！

Report from our correspondent(Reporter liu xuan correspondent Yang Fan)Today is the fourteenth AiErRi throughout the country,Hearing from wuhan university people's hospital outpatient survey found,Fifty percent of hearing loss are not caused by exposure to severe noise,But lurking in the side to disagree"Little noise"Cause of chronic damage!

　　昨天，该门诊曹永茂教授提醒，洗衣机、烧开水、空调等家中小噪音不要去习惯，要尽量回避，并学会巧妙降噪。

yesterday,The outpatient Cao Yongmao professor remind,The washing machine/The boiling water/Air conditioning and other small noise in the home not to go to habit,Want to avoid as far as possible,And learn to skillfully noise reduction.

　　家住武昌岳家嘴的王小姐最近总是感觉耳朵嗡嗡地响，到医院一检查：听力丢失35个分贝。平时很少用耳机听音乐，也从不去卡拉OK和迪吧，基本都是宅在家里，听力怎么会无缘无故下降？王小姐很是纳闷。

Live in wuchang YueGuZui wang, recently always feel ear humming sound,A check to the hospital:Hearing loss 35 decibels.Seldom use headphones to listen to music,Never go to karaoke and ted,Basic it is curtilage at home,Hearing how can down for no reason?Miss wang is very wonder.

　　曹永茂详细问诊得知，王小姐家住临街爱开窗，窗子对面是高架桥，每天至次日凌晨还有车来车往。父亲人老耳背，把电视声音开得老大，家人都很包容。那台老式洗衣机，母亲隔天就要洗一次衣服，每次脱水时洗衣机咯吱咯吱响得欢。曹永茂分析，正是这几个原因不知不觉对王小姐的听力造成了慢性损伤。

Cao Yongmao detailed interrogation,Miss wang lives in a street love open the window,The window is opposite the viaduct,Until there is car to car to the morning every day.Father's old hard of hearing people,The TV really loud,Family is very tolerant.The old washing machine,Mother to wash the clothes every other day,Every time dehydration washing machine isalso happily.Cao Yongmao analysis,Is this a couple of reasons unconsciously caused chronic damage to miss wang of the hearing.

　　人的正常听力在0-25分贝，至60岁起逐渐衰退。年轻时听神经遭破坏，很可能40岁左右就会出现听力衰退。“门诊发现不少30-40岁的人已经出现衰退，提前了一二十年。而这些听力都是在家中小噪音的影响下，不知不觉失去的。”曹永茂说，家里暗藏着不少噪音源，除了锅碗瓢盆发出的声响外，还有空调冰箱压缩机、风扇电脑风叶转动、洗衣机、电视等声音。而按照国家标准，室内噪音不得超过45分贝。2010年该科曾入户20家，用分贝仪测量了一些家庭中最为常见的声音，发现它们—点也不次于交通、施工等带来的噪音污染：

Normal hearing in 0 to 25 db,To 60 age gradually decline.Young when the nerve damage,Probably about 40 hearing loss will occur."Clinic found that some 30-40 years old have a recession,Early in one hundred and twenty.The hearing is small under the influence of noise at home,Before you know it lost."Cao Yongmao said,Home lurks a lot of noise,In addition to the noise from the POTS and pans,There is air conditioning refrigerator compressor/Computer fan blades rotate/The washing machine/TV voice.And according to the national standard,Indoor noise should not exceed 45 decibels.The division had the door 20 in 2010,Decibel meter was used to measure some of the most common sound in the family,Found them - the point is not inferior to the traffic/Construction noise pollution, etc:

　　洗衣机 高速转动 84分贝

Washing machine is high speed rotating 84 decibels

　　电吹风 强档 80分贝

Hair dryer is strong 80 decibels

　　抽油烟机 强档 77分贝

Smoke lampblack machine strong 77 decibels

　　开水壶 沸腾时 69分贝

KaiShuiHu boils at 69 decibels

　　排风扇 运行 55分贝

Fan run 55 decibels

　　柜式空调 启动时 55分贝

Cabinet air conditioner starts to 55 decibels

　　壁挂式空调 启动时 50分贝

Wall-mounted air-conditioner startup 50 decibels

　　饮水机 加热时 50分贝

When you heat water machine 50 decibels

　　电脑主机 运转时 49分贝

The computer host 49 decibels during operation

　　他介绍，如果把声音分个级：1分贝是人类耳朵刚刚能听到的声音；15分贝以下，我们常常形容为“寂静”；20—40分贝，就像情侣耳边的喃喃细语；40—60分贝，属于正常交谈的声音；60分贝以上，你会感觉到吵闹；70分贝，相当于走在闹市区的大街上；90分贝，就像身处嘈杂的酒吧；100分贝，是你家楼上装修电钻的声音；120分贝，等同于飞机起飞。

He introduced,If the sound level a:1 db is the human ears just can hear voice;15 db below the,We are often described as"The silence";20-40 decibels,Like lovers ear whispered words;40-60 decibels,Belongs to the normal voice to talk;More than 60 decibels,You will feel noisy;70 db (a),Is equivalent to walking in the streets of downtown;90 db (a),Just like in a noisy bar;100 db (a),Is your house decorate electric drill noise upstairs;120 db (a),Equivalent to the plane takes off.

　　声音在50-60分贝的时候，耳朵感觉比较舒适。60分贝就是正常谈话，不感到累的声音。当噪音超过60分贝时，你就会感觉心烦意乱；如果在超过85分贝的环境中超过8小时，耳朵就会出现声损伤。

Voice when 50 to 60 decibels,Ear feels more comfortable.60 decibels is normal conversation,Don't feel tired voice.When more than 60 decibels,You will feel upset;If in the environment more than 8 hours of more than 85 decibels,Ear injury will occur.

　　曹永茂提醒，听力受损有一个慢慢下降的过程，会先从高频音听不到开始，接着会耳鸣。正常人的听力在0-25分贝，丢失30个分贝以内，一般没有明显感觉，这也是听力稍有下降并不会引起人们重视的原因。但慢慢就会发展到连日常的对话声音都听不清，这时再来就诊就晚了。这里告诉大家一个简单的自测方法：在放一段优美的音乐时，听到的乐感不如以前强烈，或者对歌词听得不太完整，一些高音部分的歌词听不到，就要到医院就诊了。

Cao Yongmao remind,Hearing loss is a process of slowly falling,Will begin with high frequency sound can't hear,Then will be ringing in the ears.Normal hearing from 0 to 25 db,Lost within 30 decibels,Generally have no obvious feeling,This is hearing a slight decline does not cause much attention.But slowly will develop to connect everyday dialogue voice all listen to not clear,At this time to see a doctor again is late.Here to tell you a simple test method:When put a beautiful music,Hear the music less strong than before,Or listening to the lyrics is not complete,To hear some soprano part of the lyrics,Going to the hospital.

　　曹永茂建议，给家里“降噪”，家用电器尽量不要集中放在一个房间，除了定期保养和除尘外，到年限后及时更换。装修时家里多用“软包装”，比如多用墙纸、厚棉布窗帘、地毯，沙发多用布艺的，墙壁可以做些粗糙处理，这些都可以吸音隔音。另外，在窗边多摆绿色植物，尤其是体积大、叶子多的阔叶绿植物，不仅具有很强的吸声效果，还能阻挡灰尘，净化空气。

Cao Yongmao advice,To home"The noise reduction",Household appliances as far as possible don't focus on a room,In addition to the regular maintenance and dust removal,To the years after the change in time.When decorating, home use"Flexible packaging",Such as multi-purpose wallpaper/Thick cotton curtain/The carpet,Use cloth art sofa,Walls make some rough handling,These can sound-absorbing insulation.In addition,Placed in the window more green plants,Especially the large size/Leaves more green leafy plants,Not only has a strong sound-absorbing effect,Also can stop dust,Purify air.

　武汉大学生一半听力不合格 Wuhan university students half listening is unqualified

　　曹永茂还向记者披露了一项2010年全国高校听力调查：约有一半的大学生听力不合格。据悉，这项名为《言语测听》的调查由北京301医院等全国多家医院共同完成，曹永茂负责湖北地区。他们从武汉部分大学随机选取50名18-25岁的大一至大四的学生进行听力筛查，以听力损失10分贝为这个年龄段的标准，结果有超过一半人不合格。

Cao Yongmao also disclosed to reporters a listening survey 2010 national colleges and universities:About half of the college students' listening comprehension is not qualified.It is understood,This is called[Speech audiometry]The survey by the Beijing 301 hospital and other hospitals across the country,Cao Yongmao is responsible for the region of hubei province.They part from wuhan university of 50 randomly selected 18 to 25, the freshman to senior students in hearing screening,With hearing loss 10 db for this age group standards,Results more than half of them is not qualified.

　　曹永茂称，被调查大学生都有戴着耳机听MP3的习惯。“声音过大又有震动的地方，比如迪吧、卡拉OK厅，对听力的危害最大，而这恰恰是年轻人最爱去的地方。”

Cao Yongmao said,Surveyed college students have the habit of wearing headphones listen to MP3."Too much sound and vibration,Such as ted/Karaoke bar,The most damage to hearing,And this just is a favorite haunt of young people."
