Noise-induced hearing loss is the most preventable form of permanent hearing damage — and one of the fastest growing, especially among young earphone users.
How loud is too loud?
Sound is measured in decibels (dB). Prolonged exposure above 85 dB damages hearing: city traffic ~85 dB, crackers and DJ systems 110–130 dB, earphones at full volume ~100+ dB.
The 60/60 rule
When using earphones: no more than 60% volume for no more than 60 minutes at a stretch. Prefer over-ear, noise-cancelling headphones — they let you listen at lower volumes.
At work
Industrial workers exposed to machinery noise should use provided ear protection consistently and attend periodic hearing checks. Hearing conservation is an employer responsibility under occupational health guidelines — our Industrial Hearing Conservation Program helps workplaces implement it.
Warning signs
Ringing or buzzing after noise exposure, muffled hearing, or needing higher volumes — these are your ears asking for help. If they persist, get screened.
