Can Earbuds Lead to Hearing Loss?
The popular headphone design may damage hearing.


Stories are affecting every American family, here is the question. Are your ear phones ruining your hearing? Right now tonight, our millions of millions of American are walking around and listening to the music but ensuring there will not be able to hear as well in the ears ahead. Tonight the mayor of New York, says it’s time to set out alarms, ABC’s chief medical editor Doctor Rigid Beseer is stepping in.

30 years ago, people in their 20s could all hear the rustle of the leaves. The trip of rain drop, the babble of the children, now for one in five of them, those sounds gun forever, normally people were coming in their 50s or 60s with hearing loss, and that now has shifted in people their 30s and 40s. In fact, Docter Gorger like seanties has to tell more and more teens, their high peach hearing is already gone.

Designer headphones is a big business, high ticket must has. But for hearing loss, earbuds may be the most destructed. Some contests, music devices can produce 115 decibel sound. Earbuds have 5 decibels more. 85 decibel is where ear hearing damage starts. Power tools, 98 decibel along the work, 107. a jet taking off when 100 height away, 140. so how loud is the music? I would now the decibel meter. Coming in about 95, 105, wow 109, (oh my god). Here is what happens inside your ear. When strong sound rampage in your ear, the problem deep inside the co-clear are fragile hear cells. The turn by bration into sound messages to the brain. Blast mood aloud sounds and some with hear, the loud sound is brief, they were cover but if you last too long, perhaps too often, they died and they will be never grow back.

If you get 100 decibel, I would let me that to one hour a day. My vice never go higher than three quarters of your top volume and a couple of hours is enough.
