Diwali celebrations may last a few hours, but the damage caused by an excessively loud firecracker can last a lifetime. While most people worry about air pollution, burns and eye injuries during the festive season, the impact of firecracker noise on hearing health often goes unnoticed. What many do not realise is that a single firecracker burst, particularly at close range, can cause permanent hearing loss.

The danger lies in the sheer intensity of the sound. Sound is measured in decibels (dB), and the scale is logarithmic, meaning even a small numerical increase represents a substantial rise in sound energy. Many commonly available firecrackers can produce sound levels of 140–160 decibels at close range. For perspective, prolonged exposure to sounds above 85 decibels can damage hearing, while a single impulse sound exceeding 140 decibels can cause immediate injury.

According to audiologists, an extremely loud sound can cause acoustic trauma, damaging the delicate structures responsible for hearing. The cochlea, a snail-shaped structure in the inner ear, contains thousands of tiny hair cells that convert sound vibrations into electrical signals for the brain. These cells do not regenerate in humans. A sudden, powerful blast can…
