MEASURING LOUDNESS
decibel

The Decibel (dB) is the basic unit used to measure
the intensity of a sound.
image desciprion
As little as 10 seconds at a loud stadium or concert can cause permanent hearing damage.
Whisper 20dB
Normal Conversation 60dB
Lawnmower 100dB
MP3 Player 110dB
Concert / Club 120dB
Gunshots / Fireworks 150dB
140 dB image desciprion
The sound of a jet engine is about 1,000,000,000 times more powerful than the smallest audible sound.

There’s a scientific correlation between
noise levels and the time it takes to develop
permanent hearing damage.

Fans at sporting events have become extremly loud in the last few years. At recent games noise levels in stadiums have been ranging between 135 and 142 db.

Even everyday sounds such as leaf blowers and blow dryers can permanently damage hearing when exposed to for extended lengths of time.

HOW WE HEAR SOUND
  1. Sound waves entering ear canal cause eardrum to vibrate.
  2. Vibrations pass through three connected bones:
  3. Movement of the three bones starts fluid moving in the inner ear.
  4. The fluid then bends thousands of delicate hair-like cells, which convert the vibrations into nerve impulses.
  5. Nerve impulses are carried to the brain via the auditory nerve and converted into what we hear as sound.
YOU CAN’T REVERSE HEARING LOSS
Once the hair-like cells
are bent, it is impossible
to straighten them. That’s
why the hearing loss
is irreversible.
BUT YOU CAN PREVENT IT.
