Two updates in one day? What's going on? ;)
Yesterday in Speech Science we had a sound level meter, and we were measuring different sounds. Our professor told us to hold the meter 2 inches away from a hair-dryer to find out how much noise was right next to your ear while you were drying your hair. It measured 92 dB. The human voice is between 60-70 dB. 92 dB is LOUD, folks, especially right next to your ear. That's loud enough to cause damage over a period of time. Be mindful of your ears! The same thing applies to earbuds. All that volume funneled directly into your ear is dangerous. There is so much noise in the world today that we just don't think about, and our ears are not equipped to handle that constant bombardment.
