Loud noise can be very damaging to hearing. Both the level of noise and the length of time you listen to the noise can put you at risk for noise-induced hearing loss. Noise levels are measured in decibels, or dB for short. The higher the decibel level, the louder the noise. Sounds that are louder than 85 dB can cause permanent hearing loss. The hearing system can be injured not only by a loud blast or explosion but also by prolonged exposure to high noise levels. How loud is too loud? The noise chart below lists average decibel levels for everyday sounds around you. 150 dB = fireworks at 3 feet 140 dB = firearms, jet engine 120 dB = jet plane takeoff, siren 110 dB = maximum output of some MP3 players, model airplane, chain saw 106 dB = gas lawn mower, snowblower 100 dB = hand drill, pneumatic drill 90 dB = subway, passing motorcycle 80–90 dB = blow-dryer, kitchen blender, food processor 70 dB = busy traffic, vacuum cleaner, alarm clock

60 dB = typical conversation, dishwasher, clothes dryer 50 dB = moderate rainfall 40 dB = quiet room 30 dB = whisper, quiet library How can I tell if I am listening to dangerous noise levels? How can loud noise damage hearing? Understanding how we hear will help you to understand how loud noise can hurt your hearing.hoover vacuum parts pittsburgh pa One of the most common bad effects of loud noise on hearing is a permanent hearing loss. mach air force pet vacuum cleanerThis happens in the following way:vacuum cleaner bags simplicity How else can loud noise be harmful? Loud noise can increase fatigue and cause irritability. Noise can reduce the ability to pay attention to tasks.

This is a concern at the workplace when it comes to workers' safety: The ability to detect faulty equipment operation or warning signals can be reduced. Noise can also reduce productivity. Noisy classrooms can make it harder for children to learn. To read more about the harmful impact of noise in schools, view the Classroom Acoustics page. Noisy backgrounds can make understanding conversation harder. The noise can mask or cover up some of the sounds of speech, making a word like "time" sound like "dime." More concentration and energy are needed not only to listen and hear over the noise but also to speak louder. As a result, voices can be strained, and laryngitis can develop. Another common effect of loud sound on hearing is tinnitus. Tinnitus is ringing, buzzing, or other sounds in the ear.

Hearing protection, such as earmuffs or earplugs, can be purchased at drugstores, hardware stores, or sports stores. Custom earmolds can be made to fit your ears by an audiologist. Learn how to correctly insert the earplugs and earmolds for the best noise reduction. Earplugs are placed into the ear canal so that they totally block the canal. They come in different shapes and sizes, or they can be custom-made by taking an impression of the ear. Earplugs can reduce noise by 15 to 30 decibels (dB) depending on how they are made and fit.

Earmuffs fit completely over both ears. They must fit tightly so that sound is blocked from entering the ears. Like earplugs, muffs can reduce noise 15 to 30 dB depending on how they are made and fit. Earplugs and earmuffs can be used together to achieve even greater sound reduction. Use of earplugs and earmuffs is recommended when noise exposure is particularly high. Do not listen to loud sounds for too long. If you don’t have hearing protection, move away from the loud sound. Give your ears a break from the sound. Plug your ears with your fingers as emergency vehicles pass on the road. Lower the loudness of the sound. Keep personal listening devices set to no more than half volume. Don’t be afraid to ask others to turn down the sounds from speakers. Speak to the movie theater projectionist if the movie sound track is too loud. Be a good consumer. Look for noise ratings on appliances, sporting equipment, power tools, and hair dryers. This is especially important when purchasing toys for children.

Be a local advocate. Some movie theaters, health clubs, dance clubs, bars, and amusement centers are very noisy. Speak to managers and those in charge about the loud noise and the potential damages to hearing. Ask to have the noise source lowered. Can my ears get used to noise? Don't be fooled by thinking your ears are "tough" or that you have the ability to "tune it out"! Noise-induced hearing loss is usually gradual and painless but, unfortunately, permanent. Once destroyed, the hearing nerve and its sensory nerve cells do not repair. If you think you have "gotten used to" the noise you routinely encounter, you may already have some hearing damage. ExplainedELI5: Why are the motors used in kitchen blenders still so noisy in an age when you can barely hear an electric car? (self.explainlikeimfive)submitted by EDIT: wow front page...thanks! EDIT: so a few things I've learnt. 1) Everyone would like a quieter blender 2) there are some very expensive blenders 3) the noise appears to be caused by the much higher RPM of around 20,000 compared to comparable much quieter appliances 4) the need for torque also increases the noise 5) manufacturers feel it's safer for their products to be noisy 6) Ice makes a sound when blended EDIT
