Summer sounds include much more than crickets chirping. Outdoor concerts, parades, 4th of July fireworks, public transportation and construction sites all have one thing in common: High decibels of noise.
"Once hearing is damaged, it cannot be repaired," said Jyoti Bhayani, a certified audiologist at Gottlieb Memorial Hospital, part of Loyola University Health System. She particularly sounds off on headphone usage. "Hearing aids have yet to become status symbols so young people need to wise up and turn the volume down on their earbuds."
One in 10 Americans has hearing loss that affects their ability to understand normal speech. Aging is the most common cause of this condition. However, exposure to excessive noise also can damage hearing in higher pitches.
"Hearing loss due to excessive noise is totally preventable, unlike hearing loss due to old age or a medical condition," Dr. Bhayani says.
Here are the registered levels for common sounds:
Music to my Ears, or Just Plain Noise?
"It is important to know the intensity of the sounds around you," said Dr. Bhayani, who regularly cares for construction and factory workers, frequent air travelers and seniors in her practice at Gottlieb Memorial Hospital.
"I recommend using hearing protection devices for those who are exposed to excessive, loud noises and musician's earplugs, which simply attenuate the intensity/loudness without altering frequency response."
Loud Noise Permanently Kills Ear Nerve Endings Three small bones in the middle ear help transfer sound vibrations to the inner ear where they become nerve impulses that the brain interprets as sound. "When noise is too loud, it begins to kill the hair cells and nerve endings in the inner ear," Dr. Bhayani explained. "The louder a noise, the longer the exposure, and the closer you are to the noise source, the more damaging it is to your nerve endings, or your hearing." As the number of nerve endings decreases due to damage, so does your hearing. Nerve endings cannot be healed or regenerated and the damage is permanent.
Ear Bud Warning Use of ear bud headphones may save your ears from being assaulted by the noise of your teenagers' music or electronic game, but it may be damaging your child's hearing. "Three in five Americans, especially youth, are prone to develop hearing loss due to loud music being delivered via ear buds," said Dr. Bhayani.
