Your hearing is just as important as your eyesight, so why is it not taken care of like your eyesight? In your everyday life you come across a lot of noise that can be hazardous to your hearing. Examples include MP3 players, driving with the windows rolled down for a lengthy period of time, and cutting the grass. If you can hear it, it is slowly wearing down your hearing. If you are around an environment of 85dB or higher it is recommended to wear hearing protection.
