Loud Noises Causing problems in the brain.

Turn down those headphones! People who experience prolonged intakes of loud noises could very well be damaging their ears and brain to the point that it becomes difficult or impossible to distinguish certain sounds in speech. The loud sounds destroy the hair cells in the ear which are responsible for being the sound receivers. Once gone the hair cells don't grow back. Neuroscientists have been doing large amounts of research in this field, and are finding overwhelming evidence to support this claim. Tests were performed on rats using different levels of loud sounds ranging from headphones to chainsaws, to large speakers similar to those of a concert. In a large part of the rats the scientists and researchers were able to see that there was clearly damage to the auditory nerves in the ear, thus causing difficulty hearing and distinguishing certain sounds in speech. Noise induced hearing loss is a very serious issue. 15% of people who are between the ages of 20 and 69 in America suffer from noise induced hearing loss, making it a reasonable thing to investigate time and money into in hopes of helping people with hearing loss at older ages.
