近日，南昌市民赵先生致电本报称，网上流传耳机是细菌的温床，一旦戴上耳机，耳朵里的空气难以流通，温度也随之升高，耳塞表面的细菌将因此快速繁殖，不利于耳朵健康。赵先生想知道，这个传言是否真实？为此，本报记者进行了一番实验。

recently,Nanchang citizens Mr. Zhao call our newspaper said,Online spread headset is a hotbed of bacteria,Once on a headset,Ear air to flow,Temperature also increase,Earplugs surface of bacteria will be so rapid propagation,Against the ear health.Mr. Zhao want to know,That rumor is true?therefore,Our reporter a experiment.

　　多数市民从未清洗耳机 Most people never cleaning headphones

　　进行实验之前，记者在南昌街头对市民进行了随机采访。市民李女士告诉记者，她很喜欢戴着耳机听音乐，使用耳机的频率也很高，但从未对耳机进行过清洗，“应该不会有多少细菌吧？”

Experiment before,Reporter in the nanchang street to the public for the random interviews.Citizens ms. Li told reporters,She is very like to wear headphones to listen to music,Use headphones frequency is also very high,But never to a headset cleaning,"Should not how many bacteria it?"

　　市民张先生也表示，他从未清洗过耳塞，“反正耳塞是自己用，应该不会有多脏，所以觉得没必要。”不过，张先生也提出了疑问：“我若是要清理，应该如何清理才好呢？用清水还是专门的消毒液？”

Citizens Mr. Zhang also said,He never cleansed earplugs,"Anyway, ear plugs are for my own use,Should not have much dirty,So don't think it's necessary."but,Mr. Zhang also puts forward the question:"If I want to clean up,How to clean up just good?With water or special disinfection?"

　　类似的疑问，在记者随机采访的多数市民当中都存在。只有少数市民表示，如果看到耳机上有脏东西，会用纸巾或湿巾擦拭，但也没有专门清洗的习惯。

Similar question,At the press random interviews majority of people there are.Only a few people said,If see headphones on the dirty things,Will with paper towel or wet towel to wipe,But also have no special cleaning habits.

　入耳式耳机比耳塞式耳机更易藏细菌 Pleasant to hear in-ear headphones than earplugs in-ear headphones are more likely to hide bacteria

　　实验道具：三副用过的耳机，单耳耳塞式为1号，双耳入耳式为2号，双耳耳塞式为3号。

The experiment items:Third officer used headphones,Single ear ear plugs type for no. 1,Double ear pleasant to hear type for no. 2,Double ear ear plugs type for no. 3.

　　实验工具：无菌生理盐水、灭菌吸管、无菌培养皿、医用灭菌棉签等

Experimental tools:Sterile saline/Sterilization straw/Aseptic petri dishes/Sterilization cotton swab, etc

　　实验人员：南昌市西湖区疾控中心检验科应艳(注：本次实验结果仅对本次实验负责)

Experimental personnel:The nanchang city CDC clinical laboratory should be brilliant(note:The experimental results of this experiment is responsible for only)

　入耳式耳机可进入外耳道 Pleasant to hear in-ear headphones can enter the external auditory meatus

　　记者将赵先生的三副耳机送到了西湖区疾控中心检验科，其中两副耳塞式耳机，使用时卡在内耳轮，并不会探入外耳道；而另一副入耳式耳机可以直接伸进外耳道，与耳道上的皮肤接触。到底哪种耳机藏匿的细菌更多？口说无凭，实验为证。

Reporters will Mr. Zhao's third officer headphones to the hangzhou xihu district CDC clinical laboratory,Two deputy earplugs in-ear headphones,When using card, helix,Will not put it into external auditory canal;And the other a pair of pleasant to hear in-ear headphones can directly into the external auditory meatus,Faith and ears of skin contact.What kind of headset hidden bacteria more?Minister oral,The experiment to prove.

　　实验员应艳最先对1号耳机进行消毒，然后用棉签对耳机进行涂抹取样后，将棉签放进试管里，在试管中注入10毫升浓度为0.9%的无菌生理盐水，并进行振荡，这样可使棉签上的细菌均匀地混合在生理盐水中。之后，实验员从试管中取出1毫升溶液，倒在无菌平板上，再加入培养基。

Laboratory assistant should be brilliant first 1 earphone for disinfection,Then use cotton swab to headphones to daub after sampling,Will cotton swab into the test tube,In a test tube injection 10 ml of concentration of 0.9% sterile saline,And oscillation,This can make the q-tip bacterial evenly mixed in the physiological saline.after,Laboratory assistant from in vitro take out 1 ml solution,Fall in aseptic the flat,Add medium.

　　而2号和3号耳机，在实验开始前，实验员将两副耳机的左耳均佩戴了一个小时，右耳则保持原状。之后，实验员对2号和3号耳机也进行了取样。在3副耳机全部取好样后，实验员将5只平板放进了36℃培养箱内进行细菌培养。

And no. 2 and no. 3 headphones,Before starting the experiment,Laboratory technician will two headset left ear are worn for an hour,The right ear remain undisturbed.after,Lab assistant to 2 and 3 headset has also carried on the sampling.In 3 headset all take after fleas,Laboratory technician will 5 only plate into the 36 ℃ incubator for bacterial culture.

佩戴1小时细菌繁殖近5倍 Wear 1 hour bacteria breeding nearly five times

　　经过48小时培养，记者看到，5只平板中有4只有了白色斑点。实验员解释，这是经过48小时培养后形成的菌落，有多少个菌落就有多少个白点。记者发现，唯一没有白点的是消毒后耳机上的采样。

After 48 hours training,The reporter sees,Only four of the five plate only a white spot.Laboratory assistant explain,This is after 48 hours after training formed colony,How many a colony to have how many a white spot.Reporter discovery,The only no white point is on the headset sampling after disinfection.

　　之后，通过实验员计算发现，1号耳机无菌落；2号耳机左耳是佩戴1小时后的样品，菌落120个，右耳是无处理的耳机，菌落25个；而3号耳机左耳也是佩戴了1小时后的样品，菌落25个，而无处理的右耳菌落数是9个。由此可见，入耳式耳机比耳塞式耳机更易藏细菌。入耳式耳机在佩戴了一个小时后，细菌比之前繁殖了近5倍；而耳塞式耳机佩戴一个小时后，细菌比之前繁殖了近3倍。

after,Through the laboratory assistant calculation found,1 headset no colony;2 the left ear wearing headphones is 1 hour after the sample,Colony 120,The right ear is no processing headphones,Colony 25;And 3 headset wearing the left ear is 1 hour after the sample,Colony 25,Without treatment right ear colony count is nine.Thus it can be seen,Pleasant to hear in-ear headphones than earplugs in-ear headphones are more likely to hide bacteria.Pleasant to hear in-ear headphones in wore an hour later,Bacteria than before breeding nearly 5 times;And earplugs type headset wearing an hour later,Bacteria breeding than before nearly three times.

　　实验员应艳表示，细菌一般以简单的二分裂法进行无性繁殖，分裂时间一般20～30分钟。因此，从这个角度来说，佩戴了一个小时耳机，细菌最多繁殖近5倍，若是常年不洗就会加速细菌繁殖。

Laboratory assistant should be brilliant said,Bacteria general with simple binary fission method for the asexual reproduction,Split time general 20 ~ 30 minutes.therefore,From this point of view,Wearing headphones for an hour,Most bacteria breeding nearly five times,If perennial don't wash will accelerate bacteria breeding.

　耳机长时期不清理小心患病 Earphone long period not clear be sick

　　西湖区疾控中心检验科负责人表示，耳机长时间没有清洗会黏附许多细菌，千万不可轻视这些细菌，虽然大家总觉得很久没清洗耳机对身体也没多大影响，但这是因人而异的。当人体抵抗力好的时候，它们不会让人生病，若某个个体抵抗力下降，它们就会让人生病。所以，为了自身健康，还是要定期对耳机等贴身物品进行清洗消毒；并且，自己的耳机就是给自己使用，切勿给他人使用，以免生成更多的细菌。

The hangzhou xihu district CDC clinical laboratory chief said,Earphone long time no cleaning will stick many bacteria,Never despise these bacteria,Although everybody always think long time no cleaning headphones for the body also didn't make much difference,But this is because of the person different.When the body resistance good time,They won't let a person get sick,If a individual resistance drop,They will make people ill.so,In order to their own health,Or on a regular basis headphones etc. Personal items for cleaning and disinfection;and,His headset is for my own use,Do not use to others,In order to avoid generating more bacteria.

　　至于清洗方法，该负责人表示，市民可用质量较好的湿巾消毒，也可用蘸有酒精的棉签擦拭，具体操作时根据耳机质量来选择消毒方法。(信息日报 记者赵婉露、实习生吴婷/文)
