Noise Pollution

Since we can’t see, smell, or touch noise
pollution, many of us don’t notice it. People
that do notice it think it’s annoying, but they
don’t worry too much about it. However, noise
pollution is all around us, and it sometimes
causes some very serious problems.

Many things that we see every day
cause noise pollution. Trucks, motorcycles,
airplanes, loud machines, and power tools
all make a lot of noise. Even music is noise
pollution when people play it very loudly.
Noise pollution can cause a number of health problems. For example, it can lead to hearing
loss. It can also lead to sleep problems. Near airports, people often wake up at night because
the planes are so loud. They don’t sleep enough, so they get sick more easily. Noise pollution
also makes people feel stressed. Stress makes it difficult for them to concentrate, so they can’t
do their work very well. For example, if a child goes to a noisy school, he or she will probably
get lower grades than a child in a quiet school.
These are just some of the ways that noise pollution affects our daily lives.
