There are three ways to protect your hearing from damaging noise…
That’s right, move away from the sound source if possible and the decibel level will reduce.
By moving away, the decibel level of a sound will decrease by 6dB every time your double the distance from the sound. This “Inverse Square Law” teaches us that for every doubling of the distance between a sound source and the recipient of the sound, a 6 dB drop would occur if there were no echo (as from a mountain top). This would be the equivalent to cutting your noise pressure levels by 75%. For instance, if you stand 10 feet from a sound source and experience a 90 dB reading, at 20 feet you would experience an 84 dB reading in the absence of echo.”
Turn it Down
Turn down the volume on your personal stereo system (MP3, CD player, etc.), car stereo, radio, television, speaker system, PA system.
A fun addition to your classroom is the rap song by Ben Jackson – check it out! Turn It to the Left (www.turnittotheleft.com), an educational rap song on noise-induced hearing loss written by the Academy’s good friend, musician Benjamin Jackson. The rap’s “hook” urges all to take the volume control and “turn it to the left.” Ben’s live performance of this rap at the American Academy of Audiology’s conference AudiologyNOW!® 2007 in Denver received a standing ovation and much praise for its clever message aimed at young music lovers.
