I was talking on the phone with my friend Tim the other day and every few minutes he kept asking me to talk louder. The line was clear, no cell phones were used, I was talking just as I am right now and we were both in the comfort of our own homes. So it got me thinking, is it me or can he just not hear me? Well, the truth is that according to National Institute on Deafness and other Communicative Disorders, over 30 million Americans are exposed to hazardous sounds on a daily basis. And that constant exposure is giving way to a serious health problem called Noise Induced Hearing Loss. Today we will learn about the National Health Problem sweeping the nations, begin to comprehend how the ear works and how we as humans hear, we will then break down sound in its relationship to hearing while figuring just how loud is too loud. Loud music has long been attributed to Noise Induced hearing loss, but until recently it flew under the radar as a health issue for adults and elderly people. In the April 2005 edition of Pediatrics magazine, they state that an estimated 12.5% of children aged 6 to 19 years of age have noise-induced thresh-hold shifts. Noise-induced threshold shifts can range from needing to turn up the volume on your stereo to the beginnings of NIHL. The article also mentions that the previously cited percentage is almost a 40% increase since 1985. Although the statistics are alarming, Americans are still unaware because of a lack of information on Noise Induced Hearing Loss. Noise Induced Hearing Loss as documented at nidcd.nih.gov says that "Noise-Induced Hearing Loss can be caused by a one-time exposure to loud sound as well as by repeated exposure to sounds at various loudness levels over an extended period of time." This means that one time of listening to something as loud as an explosion, or years of listening to loud music can have the same effect on our hearing. What is also alarming is that the symptoms of NIHL increase gradually over a period of time but I'll get into that a little bit later. NIHL has several different forms ranging from partial deafness, tinnitus and total deafness. A person with partial deafness may never lose their hearing completely, and are often greatly helped with the use of a hearing aid.
