LOW your mp3 sounds

We may already know, or perhaps feel that loud music can damage and cause hearing problems. Teens turn deaf ear to risks of mp3 players, said title
of newspaper that I read somedays ago. In focus-group discussion with students in the Netherlands, lead Researcher Inneke Vogel found that many students
didn't know when their mp3 players were too loud.
Volume at or above 90 decibels (dB) are believed to be hazardous, and noise levels reach to 120-140 dB are uncomfortable or painful. Manufacturers, acording
to the researchers, could equip mp3 players with an indicator that displays the volume level in terms of decibels, along with a signal-such as flashing lights-
that goes off when decibel levels reach the danger zone.
It is sugested that mp3 users set the volume no higher than 60 percent of its full capacity when using ear bud style headphones, while with over-the-ear
headphones recommend 70 % as the maximum,
So friends, feel worry about your hearing ability if you cannot hear your mother yelled right on your side with no headphone on your ear..
