Exposure
to Loud Noise
When Sound Becomes Harmful
How Noise Affects Hearing
Your ears are designed to handle everyday sounds, but repeated or sudden exposure to loud noise can cause permanent damage. Inside the inner ear, delicate hair cells convert sound into signals for the brain. Once these cells are damaged by noise, they cannot grow back — leading to noise-induced hearing loss (NIHL).
Common Sources of Harmful Noise
Noise-related hearing loss can happen at any age. Some common culprits include:
​
-
Concerts, clubs, and sporting events
-
Power tools, lawn equipment, or firearms
-
Construction or factory work
-
Listening to music too loudly through earbuds or headphones
-
Sudden blasts, like fireworks or explosions
Signs of Noise-Induced Hearing Loss
​
-
Ringing or buzzing in the ears (tinnitus) after loud exposure
-
Needing to turn up the TV, music, or phone more than before
-
Struggling to follow conversations in restaurants or crowds
-
Sounds seeming muffled after noise exposure — sometimes called a “temporary threshold shift”
​
Even if hearing feels normal the next day, repeated damage adds up over time.
Prevention and Protection
​The best treatment for NIHL is prevention:
​
-
Use custom or foam earplugs in loud environments
-
Follow the 60/60 rule with headphones — no more than 60% volume for 60 minutes at a time
-
Take listening breaks to give your ears time to recover
-
Get regular hearing checks if you work in or around noise
Treatment Options
While noise-induced damage cannot be reversed, treatment can make a life-changing difference:
​
-
Hearing aids restore access to sounds and speech clarity
-
Tinnitus management tools built into modern devices can reduce ringing
-
Assistive listening devices improve communication in noisy settings
