WHY SOUND POLLUTION IS A MUST TO INVESTIGATE

WHY SOUND POLLUTION IS A MUST TO INVESTIGATE?
Sound pollution, also known as environmental noise or either noise pollution. Sound pollution is a form and level of environmental sound that is generally considered likely to annoy, distract or even harm other people. Noise is one of the most pervasive pollutant. According to Odom, noise pollution is the unwanted sound dumped into environment without regard to the adverse effect it may have.

Types of sound pollution
There are 2 types of sound pollution, which are Man Made Noise and Environmental Noise.
Man-made noise is just like traffic, subway noise, airports, constructions sites, transport, and so on. Environmental noise is like including animal sounds, barking dogs, and loud thunderstorms.

Examples

A musical clock may be nice to listen during the day but may be an irritant during sleep at night. Noise is “sound without value” or “any noise that is unwanted by the recipient”. Noise in industries such as stone cutting and crushing, steel forgings, loudspeakers, shouting by hawkers selling their wares, movement of heavy transport vehicles, railways and airports leads to irritation and an increased blood pressure, loss of temper, decrease in work efficiency, loss of hearing which may be first temporary but can become permanent in the noise stress continues. It is therefore of utmost importance that excessive noise is controlled. Noise level is measured in terms of decibels (dB). W.H.O. (World Health Organization) has prescribed optimum noise level as 45 dB by day and 35 dB by night. Anything above 80 dB is hazardous. Sound and noise are measured in decibels (dB), and according to statistics from the Centre for Hearing and Communication, continued exposure to noise levels measuring more than 85 dBA (adjusted decibels) will cause hearing loss over time.

Here is some of examples of the sound pollution level.

Source Intensity (dB) Source Intensity (dB)
Quiet Conversation 20 Radio Music 60
Loud Conversation 60 Traffic Noise 90
Lawn Mower 80 Heavy Truck 100
Aircraft Noise 100 Space Vehicle Launch 179
Beat Music 120 Jet Engine 140
Motor Cycle 105

Effects of Noise Pollution

The effects of noise pollution on the health of humans can be dangerous– including having mental, behavioural, and physical effects. For usually nervous individuals, noise can make them feel even more nervous, angry. With all these symptoms, the other long-term effects of noise pollution are often even worse.

Examples of noise pollution to human

1. Hearing Problems:

Any unwanted sound that our ears have not been built to filter can cause problems within the body. Our ears can take in a certain range of sounds without getting damaged. Man made noises such as jackhammers, horns, machinery, airplanes and even vehicles can be too loud for our hearing range.

2. Health Issues:

Excessive noise pollution in working areas such as offices, construction sites, bars and even in our homes can influence psychological health. Studies show that the occurrence of aggressive behaviour, disturbance of sleep, constant stress, fatigue and hypertension can be linked to excessive noise levels.

3. Cardiovascular Issues:

Blood pressure levels, cardio-vascular disease and stress related heart problems are on the rise. Studies suggest that high intensity noise causes high blood pressure and increases heart beat rate as it disrupts the normal blood flow.

Ways to prevent all these sound pollution

We need to protect our own health, no ones will help us, so get some good ways to prevent all the effects from sound pollution.

Examples of prevent the effects

1. Keep your space out of noise

When we can’t stop the noise at its source, we can do our best to keep it out. Sound-proofing our home will help us rest easier at night and keep our home quieter during the day as well. If we can’t sound-proof our entire home, we might want to invest in sound-proofing our bedroom, so we have at least one respite from the noise when we just can’t take it anymore.
2. Learn to meditate

When you’re feeling bad, sit very still, close your eyes and focus on taking deep, even breaths. Do 10 breaths and try to let your worries go and ignore the noise around you. No matter where you are, whether it’s on a noisy subway car or in your own kitchen, you can try this technique to calm yourself down.
3. Spend time away from city/noise

Getting away from it all is a good way to restore your emotional balance. Go to a quiet spot that’s as free of sound as possible. Stay there and enjoy the silence for a few hours until you feel that you’re good.

Never ever think that it’s just some loud sound, it can cause you, him, us into a very big trouble to our health. We only live once, so live with safe.
Thank you.
