Noise

Noise is a major but under-appreciated health problem in India — from traffic horns, construction, industrial work, loud music, religious and political loudspeakers, and firecrackers during festivals. Repeated or intense noise damages hearing permanently, disrupts sleep, and raises blood pressure.

What noise does

• Noise-induced hearing loss (NIHL) — cumulative damage to inner-ear hair cells. Cannot be reversed.
• Tinnitus — persistent ringing/buzzing after loud exposure.
• Sleep disturbance — linked to cardiovascular risk.
• Raised blood pressure, heart disease risk with chronic exposure.
• Impaired learning in children exposed to chronic noisy environments.
• Stress, irritability, reduced concentration.

The 85 dB / 60-60 rule

• Long-term hearing damage begins at roughly 85 decibels. A busy city road is around 80–90 dB; a metro train 90–100 dB; a rock concert or firecracker 110–140 dB.
• For earphones/headphones: the 60-60 rule — no more than 60% of maximum volume for no more than 60 minutes at a time.
• Use noise-cancelling over boosting volume — it lets you hear at safer levels.

India-specific hazards

• Firecrackers (Diwali, weddings, festivals) — a single loud burst can cause instant, permanent damage — especially in children.
• Motorbike and truck horns (especially air horns) — illegal above certain decibel limits but widely used.
• Construction and mining work without hearing protection — a major cause of occupational NIHL.
• DJ / live event / wedding sound systems — frequently over 100 dB.
• Loudspeakers at religious and political events — repeated exposure.

Protect yourself

• Wear ear plugs or ear muffs for firecrackers, concerts, construction/industrial work, motor sports.
• Baseline audiometry for occupational workers, with annual checks.
• Bring the volume down on earphones; prefer over-ear to in-ear for safer listening.
• Take "quiet breaks" during noisy exposures — the ear needs recovery time.
• Keep newborns and young children away from firecrackers and very loud events.
• If you have sudden hearing loss or tinnitus after a loud event — see an ENT within a few days; steroid treatment early may help.
