Dr.85 Ear Protected Earphone,Taiwan Merry price supplier

We would strongly recommend that people invest in earphones that can limit the volume to 85 decibels.

Some Headphones can project volumes up to 115 decibels. This volume is equivalent to an air-plane taking off nearby! With a dedicated design of control box, Merry Dr. 85 allows people to listen to their music at their chosen level but never exceed to 85 decibels.

Do you know that the normal talking conversation volume is 50-70 decibels? Any volume above 85 decibels can cause permanent hearing damage! The means once you lose your hearing ability, there is nothing you can do to regain it. That is how fragile our ears are!

How Bad Are MP3 players for Your Hearing?

If you're using the earbuds that come with an iPod and you turn the volume up to about 90% of maximum and you listen a total of two hours a day, five days a week, our best estimates are that the people who have more sensitive ears will develop a rather significant degree of hearing loss .

Studies we've done on behavior show that the type of earphones has almost nothing to do with the level at which people set their headphones. It's all dictated by the level of background noise in their listening environment. When we put people in different listening environments, like flying in an airplane — we used noise we'd recorded while flying on a Boeing 757 commercial flight, and we simulated that environment in our lab — 80% of people listened at levels that would eventually put their hearing at risk.
