Noise pollution comes from many sources including household appliances, social events, commercial and industrial activities, and transportation. In Dhaka City, noise pollution is a major health threat due to traffic congestion, use of brick-crushing machines, and abuse of loudspeakers. Sustainable solutions include constructing soundproof rooms for noisy machines, siting noisy industries far from residential areas, enforcing limits on loudspeaker use and public announcements, establishing silent zones near schools and hospitals, and using vegetation to absorb sound.

Gadgets like food mixer,
grinder, vacuum cleaner,
washing machine and dryer,
cooler, air conditioners, can
be very noisy and injurious to
health. Others include loud
speakers of sound systems
and TVs, ipods and ear

10. • 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.

11. • Commercial & Industrial
Activities
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.

Think of aero planes
flying over houses close
to busy airports. over
ground and underground
trains, vehicles on road—
these are constantly
making a lot of noise and
people always struggle
to cope with them.

18. Below are a few things people and governments
can do to make our communities and living laces
quieter:
• Construction of soundproof rooms for noisy
machines in industrial and manufacturing
installations must be encouraged. This is also
important for residential building—noisy
machines should be installed far from sleeping
and living rooms, like in a basement or garage.
• Noise producing industries, airports, bus and
transport terminals and railway stations to
sighted far from where living places.

19. • 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.
• Vegetation (trees) along roads and in residential
areas is a good way to reduce noise pollution as
they absorb sound.
