Question

what is noise pollution ? state three ways by which noise is produced in homes
​

Answer 1

Answer:

Noise pollution is generally defined as regular exposure to elevated sound levels that may lead to adverse effects in humans or other living organisms. According to the World Health Organization, sound levels less than 70 dB are not damaging to living organisms, regardless of how long or consistent the exposure is. Exposure for more than 8 hours to constant noise beyond 85 dB may be hazardous. If you work for 8 hours daily in close proximity to a busy road or highway, you are very likely exposed to traffic noise pollution around 85dB.

This type of pollution is so omnipresent in today’s society that we often fail to even notice it anymore:

street traffic sounds from cars, buses, pedestrians, ambulances etc.

construction sounds like drilling or other heavy machinery in operation

airports, with constant elevated sounds from air traffic, i.e. planes taking off or landing

workplace sounds, often common in open-space offices

constant loud music in or near commercial venues

industrial sounds like fans, generators, compressor, mills

train stations traffic

household sounds, from the television set to music playing on the stereo or computer, vacuum cleaners, fans and coolers, washing machines, dishwashers, lawnmowers etc.

events involving fireworks, firecrackers, loudspeakers etc.

conflicts generate noise pollution through explosions, gunfire etc. The dysfunctions, in this case, are likely caused by the conflict and insecurity and less by the noise pollution in itself, although that compounds stress levels too.

Human Diseases Caused by Noise Pollution

Whether we realize we are subjected to it or not, noise pollution can be hazardous to our health in various ways.

Hypertension is, in this case, a direct result of noise pollution caused elevated blood levels for a longer period of time.

Hearing loss can be directly caused by noise pollution, whether listening to loud music in your headphones or being exposed to loud drilling noises at work, heavy air or land traffic, or separate incidents in which noise levels reach dangerous intervals, such as around140 dB for adult or 120 dB for children.

Sleep disturbances are usually caused by constant air or land traffic at night, and they are a serious condition in that they can affect everyday performance and lead to serious diseases.

Child development. Children appear to be more sensitive to noise pollution, and a number of noise-pollution-related diseases and dysfunctions are known to affect children, from hearing impairment to psychological and physical effects. Also, children who regularly use music players at high volumes are at risk of developing hearing dysfunctions. In 2001, it was estimated that 12.5% of American children between the ages of 6 to 19 years had impaired hearing in one or both ears

Various cardiovascular dysfunctions. Elevated blood pressure caused by noise pollution, especially during the night, can lead to various cardiovascular diseases.

Dementia isn’t necessarily caused by noise pollution, but its onset can be favored or compounded by noise pollution.

Psychological dysfunctions and noise annoyance. Noise annoyance is, in fact, a recognized name for an emotional reaction that can have an immediate impact.

$\huge\underline\orange{Noise~Pollution~:-}$

Noise pollution is mainly caused by transportation and construction system . Noise pollution not only causes damage to the environment but shows negative effect on human health . Human beings who are exposed to noise pollution will develop high BP , stress , hearing loss , sleep disturbances and aggression . Using noise barriers , driving the vehicles slowly using special tyres etc ., can help lower sound pollution . The problem of noise pollution should be paid more attention . Though noise pollution is a major issue , no laws are existing in many cities of the world to control it .

Noise pollution in seas and oceans is also increasing due to ship traffic and oil drilling . This is affecting the hearing sense of animals .

→ Vehicles

Vehicles are the reson for noise pollution around us . As rapidly the technology is increasing the pollution too increasing . As more vehicles leads to noise and air pollution . So the sounds of the vehicles should be minimised or use noise barriers .

→ DJ'S

We know that marriage or any other function takes place once in a grand way but we must also know that the sound system which are produced can harm the people . People may loss their hearing ability , they may have sleeping problem . So while any functions are decided with loud sound system then they should minimise the sound system to some extent .

→ Construction system

Construction also leading to noise pollution . We know that without any noise a machine can't do work in the construction site . The constructive work should not be 24 hours as the people who are living nearby may disturb by this sound .
