How Loud Is Too Loud?

If you think hearing loss only occurs as you grow older, think again. An estimated 1 in 5 adolescents between ages 12 and 19 has slight or mild hearing loss. They're not alone; approximately 15% of baby boomers already have hearing loss.

The bottom line is that hearing loss can happen to anyone who's exposed to loud noises. For the adolescent and baby boomer segments of the population, the most common cause of hearing loss is prolonged, chronic exposure to loud noises. This is called noise-induced hearing loss (NIHL), and it's permanent. If you listen to a loud noise for too long, it begins to damage the tiny nerve cells in your inner ear that are responsible for hearing.

Decibel Levels of Common Sounds

The best thing you can do for your ears is to make an effort to prevent any further damage. To do so, it helps to understand that the intensity of sound is measured in units called decibels (dB). Here's a breakdown of a few common decibel levels for everyday noises:

• 0 dB: tiny rustle of a leaf
• 30 dB: quiet library
• 90 dB: lawnmower
• 115 dB: rock concert
• 140 dB: jet plane taking off

Ongoing exposure to sounds above 85 dB can cause permanent hearing loss over time. Even a one-time event such as a gunshot or explosion at close proximity can do lasting damage. If you have experienced this, schedule a free hearing test with a hearing care professional.
