Ear Bud Headphones Causing Deafness

Because the tiny phones inserted into the ears are not as efficient at blocking outside sounds as the cushioned headsets, users tend to crank up the volume to compensate.


“I have an audiologist friend at Wichita State University who actually pulls off earphones of students he sees and asks, in the interest of science, if he could measure the output of the signal going into their heads,” Garstecki said. Often he finds students listening at 110 to 120 decibels.


“That’s a sound level equivalent to measures that are made at rock concerts,” said Garstecki. “And it’s enough to cause hearing loss after only about an hour and 15 minutes.”
