The new regulations seek to create a healthier and more peaceful environment by controlling excessive noise generated from commercial activities, public events, loudspeakers, firecrackers, and other sources. Officials said the guidelines are intended to safeguard public health, reduce environmental stress, and improve the overall quality of life for residents.
Under the revised framework, areas within Kohima district have been categorized into industrial, commercial, residential, and silence zones, each with prescribed permissible noise limits. Industrial areas have been assigned a maximum noise level of 75 decibels during the day and 70 decibels at night, while commercial zones are limited to 65 decibels during daytime and 55 decibels at night. Residential areas have stricter limits of 55 decibels during the day and 45 decibels at night.
Particular emphasis has been placed on silence zones, which include areas within a radius of 100 metres of hospitals, educational institutions, and courts. These areas are subject to more stringent limits of 50 decibels during daytime and 40 decibels during nighttime in order to protect patients, students, and the functioning of judicial institutions.
The administration has also imposed restrictions on the use of loudspeakers and public address systems between 10:00 PM and 6:00 AM, except in enclosed premises where sound does not extend beyond the venue. Organisers planning to use amplified sound systems have been advised to obtain prior permission from the relevant authorities.
In addition, owners of diesel generator (DG) sets have been instructed to install adequate noise-control measures to minimise sound pollution. The use of firecrackers during late-night hours has also been regulated, with authorities encouraging the use of environmentally safer alternatives during festivals and celebrations.
Venue owners, including those operating marriage halls, hotels, and community centres, have been urged to ensure responsible use of sound systems and strict adherence to the prescribed limits. Event organisers have likewise been reminded to comply with all legal requirements before conducting programmes involving amplified sound.
