Take a
look at the noise levels of many common
appliances and events around the house. You
might be surprised. All sounds are measured at
the distance that a person would typically be
from the source.

The next time you operate a leaf blower, weed whacker, snowmobile, or any device
emitting more than 90 dB, please use proper ear protection.
If you are not sure how many
decibels a device is producing. Go to your local Radio Shack and
purchase a decibel meter (about 40 dollars). You might be
surprised how loud (unsafe) the world is becoming. We were.

exceeding the time limit at decibel level will produce hearing
loss.
Once hearing
loose or damage occurs it almost never returns.
