Educational information, not medical advice. This article is written to help you understand common ear and hearing issues. It is not a substitute for professional diagnosis or treatment. If your symptoms are severe, sudden, or persistent, please consult a qualified doctor or audiologist. For urgent symptoms (sudden hearing loss, bleeding from the ear, severe pain with dizziness, or a head injury), seek medical care the same day.

Sound above about 85 decibels can damage hearing with prolonged exposure, and every 3 dB increase halves the safe time. Traffic, horns, mixers, DJ speakers and firecrackers often exceed that. This chart puts everyday Indian sounds into perspective, with approximate values.

The direct answer

Regular exposure to sound above about 85 decibels (dB) can damage hearing over time. Because the decibel scale is logarithmic, every 3 dB increase roughly halves the time you can safely listen. A quiet room is around 30 dB, and normal conversation around 60 dB. Loud events, traffic and firecrackers can reach levels that harm the ear in minutes or even instantly.

Approximate levels of everyday sounds

These are typical, approximate levels. Actual values vary with distance, equipment and surroundings.

About 30 dB: a whisper, a quiet bedroom at night.
About 50 to 60 dB: normal conversation, a quiet office, background TV.
About 70 to 80 dB: a busy street, a vacuum cleaner, a noisy restaurant.
About 80 to 90 dB: heavy traffic, a mixer-grinder, a crowded market.
About 90 to 100 dB: a motorbike or auto-rickshaw at close range, a power drill, a loud train passing.
About 100 to 120 dB: a vehicle horn at close range, a nightclub, wedding DJ speakers, a live concert.
About 120 dB and above: an ambulance siren very close by, a jet at close range.
140 dB and above (peak): many firecrackers at close range, gunshot. Instant damage is possible.

How long is safe? (NIOSH guide)

85 dB: about 8 hours.
88 dB: about 4 hours.
91 dB: about 2 hours.
94 dB: about 1 hour.
97 dB: about 30 minutes.
100 dB: about 15 minutes.
106 dB: under 4 minutes.
112 dB: under 1 minute.

Sudden, very loud sounds such as firecrackers can cause permanent damage instantly, without any build-up. See Diwali firecrackers and your hearing and wedding season DJ noise.

How to check your own environment

Use a sound level meter app to get an idea. See NIOSH sound level meter app. Phone microphones are approximate, so treat readings as a guide.
A simple rule: if you have to shout to be heard by someone an arm's length away, the level is likely above 85 dB.
For headphones, keep the volume at or below 60 percent, for no more than about an hour at a time. See the 60/60 rule for headphones.

Protect your hearing

Increase your distance from the source.
Take listening breaks and limit exposure time.
Use earplugs or earmuffs in loud places and at work. See safe noise levels at work.
Choose quieter appliances and devices where you can.

Get your hearing checked

Signs of damage include ringing, muffled hearing and difficulty following speech in noise. See signs of hearing damage from loud music. A free hearing test shows where your hearing stands and gives you a baseline.
