- Loud music: Playing music in high volume,
- Television: Television also causes sound and watching television for long hours in just as harmful for ears as they are for eyes.

People should be made aware that excessive noise beyond certain limits may cause deafness.
They should know that injuries caused by sound pollution are often irreversible.
There should be minimum use of sound producing instruments. There should be proper regulations for the use of loudspeakers and other devices that produce noise beyond that are beyond the toleration limits of human-beings.
The Pollution Control Board and the High Court have already taken effective measures to bring sound pollution under control. Adequate measures should be taken to ensure that noise related restrictions are not violated.
Anti-pollution laws should be enacted and enforced.
Ban of fire crackers should be imposed and electric horns should be replaced by bulb horns.
The use of microphones should be controlled and regulated.
Noise pollution is real. It is not just a mild annoyance. It can negatively effect the lives of both humans and animals. It poses severs threats such as environmental hazards, health problems, habitat loss, etc. It also changes in the ways in which people cohere.
