3M 1425经济型耳罩

2024年耳罩的正确选择方法及清理维护注意事项噪音给人带来生理上和心理上的损害主要有损伤听觉和视觉器官有所损害。

据噪音对人体健康调查表明，该区域内噪声每上升一分贝，就会影响人的正常工作情绪，使人容易急躁、易怒。

干扰正常休息和睡眠的质量及工作效率。

所以，保护听力就格外的重要，当前主要通过佩戴耳塞和耳罩进行预防。

耳塞主要用于工作场所，其舒适度并没有耳罩那么明显，所以，如何正确根据自己所在的环境选择正确的耳罩就显得额外重要。

首先要进入的就是分贝的概念，声压级单位：dB。

20分贝：很安静，几乎感觉不到；犹如窃窃私语。

50分贝：一般室内说话的音量；犹如正常交谈。

70分贝：吵闹、有损神经；犹如街道环境声音。

75分贝：很吵，神经会有损伤；会达到人体耳朵舒适度上限。

80分贝：非常吵闹，犹如：嘈杂的办公室，高速公路上的声音。

90分贝：吵闹加剧，听力受损；犹如：嘈杂的酒吧，电动锯据木头的声音。

100分贝：难以忍受、呆一分钟即暂时致聋；犹如：气压钻机声音，压缩铁锤锤打重物的声音。

120分贝：极度聋或全聋，到达人体听觉的最大极限。

如何掌握耳罩正确的使用方法：将耳罩头箍拉伸到最大打开位置并跨过头部上方，将罩杯罩住双耳；放松头箍回位，调整罩杯的高度直到头箍能够支持罩杯，并且双耳感到舒适为止；耳罩的软垫应紧密贴合头部。

调整头箍以保证正确箍紧，有效地隔绝噪音。

掌握耳罩的清洁方法：安装推荐的维护和清洁方法进行处理，以维护最佳的降噪效果和性能。

只能清洗耳罩的表面。

使用中性的肥皂水和温水，不要浸泡在水中。

不要使用溶剂，例如酒精、丙酮、无水洗手液或者有羊毛脂的产品清洁耳罩。

不要将产品存储在温度高于85℃的环境中。

为确保稳定的降噪效果，良好的卫生和舒适性，建议定期检查耳罩是否开裂或破损的部件，特别是密封垫。

2024年耳罩的正确选择方法及清理维护注意事项（二）2024年是一个科技高度发达的时代，耳罩作为个人音频装备的重要组成部分，已经成为人们生活中不可或缺的一部分。

3M Hearing ConservationLeading the advancement of hearing conservationNoise is everywhere. It is the most pervasive environmental pollutanton the planet. Virtually everything we do makes noise, and the morewe do it, the faster we do it, and the more of us there are - the morenoise is made. In fact, silence, by which we mean complete absolutequiet, is so rare that few of us have had the joy, or perhaps even thepossibility to experience it. If we have, it is so unusual that we canlikely cite the time and place of its last occurrence. The opportunitiesto savor such tranquility are rapidly vanishing.Know your hearing protectionThe Sound Around UsNot only is noise present in our daily routines and recreational activities,but upwards of 5 million Americans, possibly as many as 30 million, work in hazardous noise on a daily basis. Estimates from the National Institutes of Health suggest that hearing loss afflicts 28 million Americans. About 1/3 of those cases are at least partially attributable to noise. Later in this booklet we’ll tell you how the ear works and how noise can affect it, so you will understand why you should protect your ears from too much sound today in order for your hearing to serve you tomorrow.In a world as noisy as ours we frequently tune out. Moreover, our culture is so visually dominant that often sight overwhelms the other senses such as audition (the hearing of sounds), which is habitually relegated to second-class status. The purpose of this pamphlet is to address these issues – to increase your appreciation and awareness of the sounds around you and to provide some tools to help you protect yourselves from loud, annoying and/or hazardous sound.Pain threshold Dual protection may be needed Short exposures can cause perma-nent hearing loss Prolonged exposure causes moderate to severe loss. Wear hearing protectors with extra careProlonged exposure causes mild to moderate loss. Hearing protectors requiredProlonged exposure causes slight hearing loss. Hearing protectors recommended Residential boundary-noise limit Sleep disruption may begin Threshold of HearingJet Takeoff Basketball Game Crowd Noise Large Stamping Press Chain Saw Vacuum Cleaner Inside Mid-Size Auto (65 mph)Drilling Concrete Leaf Blower Conversation Floor Fan Quiet Library Rice Krispies Watch Ticking Quiet Wilderness (no wind)Measuring NoiseNoise hazard depends on the level (sometimes called intensity) of the noise, its duration , and how often the exposure occurs. The point above which regular exposure to sounds becomes hazardous is a level of about 85 decibels (abbreviated dB, or sometimes dBA which is the value that more closely corresponds to human hearing). Noise is measured using a soundlevel meter.You Don’t Get “Used to Noise”Noise does not have to be uncomfortably loud, or even painful, to be damaging. You may think your ears are “used to the noise,” but what has probably happened is that your hearing has been temporarily dulled or that hearing loss has already begun. A Rule of Thumb When you feel the need to shout in order to be heard three feet away, the noise levels are probably 85 dBA or more and hearing protectors are ing Your Ears to Assess Noise Risk If, after the noise stops, you notice a ringing, buzzing, or whistling in your ears that wasn’t there before, this is a warning indicator. Called tinnitus , this is like a “sunburn” of the nerve cells of your inner ear, indicating that they have been irritated and overworked. Tinnitus is especially noticeable in a quiet place, such as when you are trying to go to sleep at night. If you don’t protect your ears from noise, tinnitus can become a permanent, constant annoyance in your life.Apparent muffling or softening of sounds after noise exposure is a warning sign that your hearing is affected by a temporary threshold shift . Repeatedly exposing your ears without protection can cause the shift to worsen and become permanent, resulting in untreatable damage to your hearing ability.Hearing ProtectionHearing loss due to noise is almost entirely preventable by judicious use of hearing protection. To find what is best for you, try different devices from the wide variety available today. Be sure to carefully read the instructions because hearing protectors must fit properly and be worn correctly to do the job. Hearing protector effectiveness is specified by a Noise Reduction Rating (NRR), typically ranging from 15-35 decibels. In practice the protection that normally can be achieved is about 10-20 decibels. The more carefully you fit and wear hearing protectors, the higher your protection will be. Hearing protectors may feel uncomfortable at first, but give yourself a chance to get used to them, just as you do with a new pair of shoes or glasses.Foam plugs, made from expandable slow-recoveryfoam, provide the best combination of comfortand protection for most users. They must be properlyprepared for insertion. One size fits most. Once in theear, foam plugs expand to provide a snug and securecustom fit. The two most common complaints about foamplugs (“not enough protection,” and “they don’t stay in”)are almost always solved by greater practice and care ininsertion.Premolded plugs are made from flexible materialsthat are preformed to fit the ear. They are generallyavailable with a joining cord to prevent loss. Althoughthe version pictured at the left is a one-sized product,many premolded plugs are sold in two or more sizes andmust be individually sized for each ear. If after aperiod of regular wear you’ve been unable to get used toyour earplugs, try another size, type, or brand of hearingprotector.Earplug Fitting TipPress firmly cupped hands over your ears while listening to a steady noise. With properly fitted plugs the noise levels should be about the same whether or not the ears are covered.How Much ProtectionDon’t get hung up on the NRR, the government-mandated noise protection factor that appears on all hearing protector packaging. The numbers are based on optimized laboratory tests that, in practice, represent what only a few of the most-motivated best-trained users can achieve. Your best bet is to use the NRR only as an indicator that a product was designed and tested for noise reduction. Except for very loud noises such as gunfire where selection is more critical, most hearing protectors provide sufficient protection when worn properly and consistently. Foam plugs or earmuffs, or a combination of the two generally provide the highest levels of protection.Slowly roll andcompress foamplugs into a verythin crease-freecylinder. Whilecompressed,insert plug wellinto the earcanal.Fitting is easier if youreach around the head to pull the ear outward and upward during insertion.Keep the plugs cleanand free from materialthat can irritate theearcanal. They maybe washed in mildliquid detergent andwarm water. Squeezeexcess water from theplugs and allow to fullyair dry. Washing may berepeated several times. Discard plugs if they noticeably change their firmness or do not re-expand to their original size and shape.Premolded plugs willnormally last severalmonths or moredepending uponthe type, andenvironmentalfactors. They shouldbe replaced if theyshrink or swell, hardenor soften, tear, crack, orbecome permanently deformed. Wash them in warm soapy water and rinse well.When dry, store them in a carrying case.Reach around the backof your head andpull outward andupward on the earwhile insertingthe plug until youfeel it sealing.This may seem tightat first, especiallyif you’ve never wornearplugs. Carefully twist the plug to break the seal for a slow, safe removal.Hearing ProtectionInitially you may be concerned that you’ll be unable to hear while wearing protection. However, unless you already have a significant hearing loss you’ll be surprised how well you can hear speech and many other sounds while protected in the noise.When you properly wear hearing protectors you’ll be protected from temporary hearing shifts so that you are able to hear as well after a noise exposure as when it started. People with hearing loss also benefit, since without protection noise will continue to damage their hearing until it is difficult to distinguish sounds under even the best of conditions.Semi-inserts, also called canal caps, consist of pods orflexible tips on a lightweight headband. Because they arequick to put on and take off and easy to store around theneck, they are ideal for intermittent use. Those thatjust cap the canal entrance give rise to a larger occlusioneffect (see above) which can be annoying to some wearers.Earmuffs have rigid cups with soft plastic cushions thatseal around the ears to block noise. Muffs come in one-position or multi-position bands, and are also sold in stylesfor attachment to hard hats. Cushions may be filled withfoam, liquid, or a combination; let personal preference beyour guide. For sustained exposures to very loud noises,or if you feel the need for more protection, wear muffs andplugs together (dual protection) for an additional 5-10dB of noise reduction.Hearing Protector Fitting TipWhen either a plug or muff is properly fitted, the sound of your own voice should change, becoming deeper, hollow, or muffled due to what is called the occlusion effect. If you don’t hear the change, or if it isn’t the same in both ears, you have not obtained a proper fit and acoustic seal in either one or both ears.Tip: Talking in NoiseWhen you wear plugs or muffs in noise you tend to speak less loudly than otherwise because the protector makes your own voice seem louder and the surrounding noises seem quieter. So, you have to speak up – speak more loudly than you think you need to. Others will appreciate this, and your message will be better understood.Hold the large endsof the pods andswivel them todirect the tipsinto the earcanalopenings. Firmlypush and wigglethe pods intothe canals untila snug seal isobtained. Pulling on the outer ear while pushing on the pods will behelpful to most wearers.Most semi-inserts can becleaned in the sameway as premoldedearplugs. Since theheadband holdsthe tips in place toprovide an acousticseal, don’t tamperwith it or the protectionthe device provides maybe reduced. Many manufacturerssell replacement tips.Cushions can be cleanedwith warm soapy waterand rinsed thoroughly.Do not use alcoholor solvents. Cushionsnormally needreplacing at leastyearly, or wheneverthey become stiff,cracked, or no longer seal.Don’t modify earmuffs in any way, and especially do not stretch or abuse the headbandsas this will reduce your protection.Muffs must fully enclosethe ears to sealagainst the head.Adjust the head-band so cushionsexert even pressurearound the ears toget the best noisereduction. Pull hair backand out from beneath the cushions. Don’t store pencils or wear caps under cushions. Thick or poorly fitting eyeglass tem-ples may also cause some loss in noise reduction.Specialized Hearing ProtectorsMusician’s EarplugsCertain earplugs are designed for moderate noise reduction andbetter sound quality (more uniform attenuation across therange of frequencies). For many sound exposures such as livemusic, public events, and transportation, these devices providethe needed protection, while making listening easier and moreenjoyable. The effect with these earplugs can be compared towearing medium neutral-gray sunglasses instead of very darkcolor-tinted lenses that dramatically change one’s perception. TheProfessional Musician 3M™ E-A-R™ Plug is one such product.Special types of custom earmolds also provide this feature.Custom Molded EarplugsCustom earmolds can be very comfortable. They are suitable for useas hearing aids and as earplugs for hearing protection. As earplugsthey can be made from a custom impression of the earcanal usingmaterial with the consistency of thick honey (usually sent to a labfor final fabrication), or in the case of a unique product calledthe 3M™ CustomE-A-R™, by injecting silicone into a speciallydesigned (yellow) bladder. The bladder design is safer to make,ready to wear, and can be immediately acoustically verified forfit. Such fit verification is important since the acoustic seal of anearmold can be compromised if the impression is not precise for anexact fit.Electronic EarmuffsSome earmuffs use a microphone embedded in the earcup topickup sounds and transmit them through the earmuff to anearphone inside. This allows better hearing at low soundlevels without the need to remove the device, while stillproviding sufficient protection at higher sound levels. Typicallythe electronics in the muff limit the amplified sound to apredetermined safe value such as less than 85 dBA. These muffscan be excellent for use while hunting or on the firing line, and forthose with a mild hearing loss they can actually amplify sounds, thusmaking it easier to hear.Active Noise Reduction (ANR)Today it is possible to use sound to cancel sound. A microphone withinthe earmuff detects the sound passing through the cup walls andsends that signal through circuitry to generate an anti-phase versionthat is rebroadcast through a speaker in the cup. The result is soundcancellation, but due to physical limitations this process only workswell in the lower frequencies, middle C and lower. This is effective incertain military situations, and in general aviation, especially when thedevices also include communications. The principal consumer applicationis reduction of nuisance noise such as experienced while traveling. An ANRearmuff, which also plugs into an earphone jack on entertainment devices, can provide balanced noise reduction while simultaneously permitting listening to music or movies.Your Hearing How it works and how we measure it How We HearHealthy inner-ear nerves (hair cells) are the key to good hearing.Although some die off naturally as you age, many more are killed early if your ears aren’t protected from harmful noise.The outer ear collects andthe earcanal to the eardrum.The middle ear contains a chain of three tiny bones, called ossicles, which link the eardrum to the inner ear. When sound waves strike the eardrum, the ossicles conduct the vibrations to the cochlea in the inner ear.Measuring HearingHearing is measured by a professional with an audiometer that sends tones to each ear through earphones. You listen carefully and respond each time you hear a tone. The levels at which you can barely hear the tones are your hearing threshold levels .Your thresholds (measured in decibels) are recorded on a chart called an audiogram , for tones at different pitches or frequencies (measured in “Hertz,” which is a special term for cycles/second). Normal thresholds fall within the unshaded area on the chart. When hearing loss occurs the thresholds fall into the shaded areas, meaning sounds must be increased in level for you to hear them.It is a good idea to have a complete hearing evaluation even if you don’t suspect a hearing problem. This gives you a baseline if problems occur. Professionals suggest evaluations every 10 years; more often for those over 50. If you anticipate regular exposure to high-level noise, for example if you are an avid recreational shooter, you may wish to obtain more frequent tests until you can assure that your hearing is stable. Unusual changes would alert you and your hearing specialist (audiologist or otolaryngologist) to look for noise-related (inadequate or improperly fitted protection) or medical causes before it’s too late.Do Yourself a Favor -Save Your Hearing!Person-to-PersonCommunicationInarguably, the most important functionof our hearing is communication. Aperson with hearing loss may not hear orunderstand family members and friends,particularly women and children withhigh-pitched voices. Communication overthe telephone for business or pleasurebecomes more difficult. The individualwill confuse similar-sounding wordsand mistake the message. Embarrassedto ask the speaker to repeat, the listenermay just “tune out.” Conversing ingroups is most difficult, especially ifthere is background noise. People withhearing loss often become socially isolatedas others find it too much trouble to speak to them.What’s more, hearing aids can’t completely correct the problem because louder sounds are not necessarily clearer to the damaged ear.Often the message is as much in the sound of the voice as in the content of the speech. Poet Maya Angelou has observed, “Words mean more than what is set down on paper. It takes the human voice to infuse them with shades of deeper meaning.”Effects of Age and Noise on HearingHearing loss from the natural aging process causes agradual hearing decline, as shown in the figure to theright. It affects mainly the ability to clearly hear high-pitched sounds such as children’s voices, rustling leaves,and some musical instruments.Although age-effect hearing loss up through age 60 doesnot usually impair one’s ability to hear and understandspeech, problems occur when noise-induced loss is addedto age loss. The noise-induced component can comefrom occupational exposures as well as the many loudrecreational sounds we willingly expose our ears to on adaily basis. With noise damage, even a 30-year-old canhave trouble listening in situations in which backgroundsound is present, such as in restaurants and other socialsituations.Sounds You Want to Hear A hearing-impaired person may notbe able to enjoy ordinary sounds ofnature or even the sounds of pets, and distortion from damaged hair cellsmay make music seem like “just a racket.” It becomes difficult to detect problems with tools or car engines by listening for changes in the soundsthey make. It can be inconvenient to miss the sound of the alarm on your wristwatch or the phone ringing in the next room. Hearing-impaired people worry about getting hurt by missing danger signals such as warning beepers or smoke detectors. Remember:You Need Your Hearing! These comments from people with noise-induced hearing loss show why it is worth the effort to wear hearing protectors properly: your qualityof life depends on keeping your good hearing. Once hearing is lostit is gone forever. And if you aren’t willing to wear an earplug for hearing protection today, how would you tolerate wearing a hearing aid that fits to the ear with an earplug-like tip, every day and every waking hour for the rest of your life.Even if you already have some hearing loss, it is still essential to wear hearing protectors from now on to prevent the loss from worsening. Carry them with you like a pair of sunglasses so that whenever annoying or potentially damaging sounds assault your ears, you have the protection you need. It’s never too late to start conserving your hearing!…Always this ringing in my ears.My daughter no longer seems to speak clearly.I miss the birds, the wind in the trees, the whispers.I miss all the good sounds…Written by:Elliott H. Berger, M.S.,Senior Scientist, Auditory ResearchNoise Is All AroundBe aware of noisy situations such as theones illustrated to the right, so you canprotect yourself and enjoy a lifetime ofgood hearing.Occupational Health &Environmental Safety Division3M Center - Building 235-2W-70Saint Paul, MN 55144-1000Sales Assistance: 1-800-328-1667Technical Assistance: 1-800-243-4630Website: /OccSafety © 2010 3M Company.3M and all other trademarks used hereinor hereon are trademarks of 3M Company.These hearing protectors help reduce exposure to hazardous noise and other loud sounds.
