Have you ever been to a concert or special event in which loud music is playing nonstop? The constant exposure to this type of sound could cause noise induced hearing loss (NIHL). The reason for this is because delicate parts in our inner ear or hair cells can be damaged, affecting hearing health. These hair cells are the ones responsible for converting sound energy into electrical signals that travel to the brain, once they are damaged there is no turning back.

Individuals need to become aware about the causes of NIHL. According to the National Institute of Deafness and other Communication Disorders (NIDCD), NIHL could be caused by a constant exposure to loud sounds over an extended period of time, such as a person working in a loud factory or by a one-time impulse sound such as an explosion.

The effects of this exposure could be devastating. Hair cells as well as auditory nerves are damaged and they cannot be healed. Impulse sounds may lead to instant permanent hearing loss, which may be accompanied by ringing ears. An article by NIDCD talks about a study in which it is shown that constant exposure to loud noise can cause formation of molecules inside the ear that damage hair cells and result in NIHL.

Always protect your hearing by using earplugs when being exposed to loud noise. If you start having trouble understanding speech or begin to hear distorted or muffled sounds, you may be suffering from loss of hearing. Do not hesitate to contact your local Audiologist such as Dr. Duran. This expert will correctly diagnose you by performing a hearing test.
