How are noisy celebrations and DJs affecting the hearing of humans?
A research paper highlights the risks of 'cochlear synaptopathy' caused by prolonged exposure to high-volume music at celebratory events. Experts warn that sound levels exceeding 90-120 dBA can cause permanent, undetectable hearing damage even when outer hair cells remain intact.
Why it matters
It raises public health awareness regarding the long-term auditory consequences of increasingly loud urban and rural celebratory environments.
The story so far: Noisy celebrations have now become a part and parcel of urban as well as rural Indian life. As vehicles packed with powerful new speakers known as DJs are available at lower prices and the competition to play high-volume music has reached all parts of the country, it is posing a challenge to body and soul.
A new research paper published in Scientific Reports in January 2026 uses the term ‘subclinical hearing damage’ to identify the effect on hearing due to high-level amplified music at recreational/celebratory events. While the researchers focused on recreational events, the conditions match those of celebratory events in India where sound pressure levels cross 90 A-weighted decibels (dBA) or more for prolonged periods, sometimes days. These sound levels have been known to cause noise-induced hearing loss.
