• Social Events Places of worship, discos

and gigs, parties and other social events also create a lot of noise for the people living in that area. In many market areas, people sell with loud speakers, others shout out offers and try to get customers to buy their goods.

Printing presses, manufacturing industries, construction sites, contribute to noise pollution. In many industries, it is a requirement that people always wear earplugs to minimize their exposure to heavy noise.

Below are a few things people and governments can do to make our communities and living laces quieter:

• Community law enforcers should check the misuse of loudspeakers, worshipers, outdoor parties and discos, as well as public announcements systems.

• Community laws must silence zones near schools / colleges, hospitals etc.
