Sound in the 21st century

Posted: October 17, 2010 in Uncategorized

A certain article came to my attention recently that explains a few things most people don’t know about sound.

This is a very important read for anyone with EARS…..especially younger people with ears that still work (for now).

There are a variety of topics explained in this article but there is one in particular relating to HEALTH that I would like to reiterate. I would like to bring up the issue of headphone abuse. I see it all the time: people in their teens or early twenties who can’t take a step outside without having earbuds in. This is a twofold problem.  Not only are we dealing with the excessive loudness, but exposure over time (the more important of the two). It’s quite common for people to listen to music in earbuds with a loudness over 100dB. Exposure at these levels should not exceed 1 to 2 hours a day.  Hearing loss is no joking matter, and not something that can be repaired either.  Once it’s gone, it’s gone.

Two very alarming statistics were stated in the CNN article:

“Over 19 percent of American 12 to 19 years old exhibited some hearing loss in 2005-2006”

“One university study found that 61 percent of freshmen showed hearing loss”

We are currently on a highly dangerous path of introducing an entire generation of adults who will have significant hearing loss by the age of 30. The ironic part of this is that these earbud abusers won’t be able to enjoy the music they love so much when they are older because they won’t be able to HEAR it. It’s almost like a drug. Users take a drug so much that when they do use after years of abuse, its effects are no longer a positive experience.
