While conversations about hearing-impaired earplugs tend to fade, the volume at work, in restaurants, and in restaurants can become ever weaker on the street a permanent hearing loss develops. How loud is so loud?
Long History In Short, You Should Avoid 85+ dB
With prolonged and repeated exposure, sounds that exceed 85 decibels can cause permanent hearing loss. Although 85 dB sounds like a lot, but there is a good chance that you are exposed to 85 dB of sound a day. For example, each time you open your vehicle window while driving at a speed of 50 miles per hour, you will be exposed to approximately 89 dB of sound.
Before you get too nervous, think about how long and how often you are exposed. Most doctors agree that you can get by with 85 dB of sound for about eight hours. But even after those hellish eight hours of mowing a lawn or having shut down windows, there's a good chance you will not sustain a permanent hearing loss.
You see, there are little hairs in your ear called Steroids. These hairs vibrate as sound waves enter your ear, and these vibrations are transformed into neuronal information that your brain can understand. Prolonged exposure to loud noises (such as an eight-hour lawnmowing session) will depress your little earhairs, like blades of grass that have been kicked. When these hairs are depressed, they stop vibrating, which means your brain is not receiving any sound.
But like blades of grass, your little ears can spring up overnight. Occasional long exposure is no big deal ̵
It is also important to keep this in mind just because you have a persistent hearing loss. That does not mean that you have a higher tolerance for the volume. 85 dB is the universal threshold for hearing loss, even if your ears are already blown out.
In the range of 85 dB, drivers with open windows and amateurs need not worry about lawn care. Most people who repeatedly experience eight-hour exposure at 85 dB are construction workers, bars and sound engineers. This does not mean that you are safe from noise-induced hearing loss – you do not have to worry so much about the 85-dB threshold as someone who works in a noisy environment.
What happens after 85 dB?  The way we measure sound can be a bit misleading. They assume that 80 dB is twice as loud as 40 dB. This is not the case. The volume level doubles with every 10 dB gain, so 80 dB is eight times the size of 40 dB. In this way, it is similar to earthquake measurements on the Richter scale.
As you increase the volume, your noise level decreases at a similar rate. At 90 dB, a four-hour exposure time leads to permanent hearing loss. Go up to 95 dB, and your ears can only weigh two hours. Raise the volume to 110 dB, and your ears can only last 1 minute and 29 seconds.
Even if you're not exposed to eight awful hours of mowing, there's a good chance that you've spent several hours repeatedly rocking a concert, spending a few hours in a bar, a night out at a football match, or a full day listening to music hear through your earphones. Well, the average rock concert is about 120 decibels, a busy bar about 90 decibels, the NFL games about 90 dB, and most earphones can reach the mark of 115 decibels.
It's easy to see what an average day looks like on dangerous noise levels. However, if you want to continue doing normal things, what precautions can you take to keep your ears safe?
If you work in a noisy environment, buy some earplugs
If you're a professional contractor If you work as a worker, musician, bartender, or in some other noisy environment, you can not help but hear deafening sounds , Unfortunately, you can not tell a bulldozer or a speaker that you have to silence him, so you have to use earplugs.
Fortunately, modern earplugs are inexpensive, convenient and practical. Some of them aggressively block incoming noise, while others actively lower decibel levels without affecting sound quality. If you need help finding a good pair of earplugs, there is a great article on Review Geek that goes through a variety of high quality earplugs.

I know Your friends and colleagues will make fun of you when you wear earplugs. You can tell them how cool you are, if you care about your health, or you can disguise your earplugs as earplugs. At Amazon, there are many earplugs earphones, and some earphones are so dense that they can block external noise. Keep in mind, however, that playing sounds through earplugs does not magically dissipate the incoming decibel level of external sounds, and dedicated earplugs are always better for sustaining your hearing than a pair of earplugs Pollution
As it turns out, there are people who live in big cities, exposed to a high risk of noise pollution. Usually this is attributed to "ambient noise" and "noise pollution". Traffic and construction can fill a city's morning commute with loud noises, and late nights in bars and restaurants can be a nightmare.
If you're worried that city life is ruining your ears, you should probably check how many decibels you're exposed to all day. Download a decibel meter to your phone, such as: Sound Meter or Sound Analyzer, or use a dedicated decibel meter for more accurate sound measurements. If you are not satisfied with the noise levels you are exposed to, you should buy earplugs or change your routines.
Music lovers should wear earplugs with lower volume but no quality.
There is a good chance You have already heard this, but you should always wear earplugs at a concert. The average rock concert is about 120 decibels and there is a good chance that the shows on your dive site or the DJ in your favorite club will get even louder. There are many earplugs that lower the decibel level without affecting the sound quality. So there is no excuse not to wear earplugs. If your friends make fun of you, wait until the next day and ask how their ears feel.
Concerts are not the only thing that music lovers have to worry about. Headphones and earphones can usually reach a volume level well in excess of 100 dB, and the sound system in your car or at home may become even louder.
You may think that you like loud music, but you probably all like to hear the details your music has to offer. If your speakers or headphones sound like crap at low volume, consider investing in higher quality audio devices. You do not have to break the bank. There are many high-quality headphones and speakers that cost less than $ 200.
If you do not want to store a few hundred headphones with some new headphones, you should adjust the equalizer settings to compensate for the poor sound quality. Most phones and amplifiers have powerful, automatic EQ settings and can really enhance the audio quality of your current setup.
