C) Silencing the devices and automobiles making loud noises.
D) All of the above

Answer 1

Hint:Any unwanted or excessive sound that has harmful effects on human health and environmental quality is defined as the Noise pollution. A sound which can potentially affect our health negatively need not be only loud sound. Any unwanted sound can affect your health and environment.

Complete step by step solution:
Noise pollution is an invisible danger which can’t be seen but can be felt with our sense organs. It is present on land, in water bodies and the air. Noise pollution is considered to be any unwanted or disturbing sound that affects the health and well-being of humans and other organisms.

The loudness of sound is measured in decibels. Noise above over a prolonged period of time may start to damage our hearing. Loud noise above can cause immediate harm to our ears.

Although excessive sound is often the culprit, it’s important to note that any unwanted sound can potentially affect our health negatively, no matter how loud.

The measure which must be taken to reduce the noise pollution is as following:
The machines which are being operated in factories and industries produce loud and undesirable sound which contributes to the noise pollution. To reduce the noise pollution due to industries and factories, these industries and factories must be established away from residential areas.

The trees act as the hindrance in the path of sound. So, when trees are planted around the buildings then the sound reaching the building gets reduced. Hence, plantation of trees around the building can be a measure to reduce the noise pollution.

Devices and the automobiles majorly contribute to the noise pollution. So, silencing the devices and the automobiles will reduce the noise pollution.

Hence, option D is the correct answer.

Note: The sound which is unpleasant to our ears can be termed as the noise pollution.
The noise pollution causes fatigue, anxiety and other negative impacts on our health. So, the reduction of noise pollution must be considered under the public health issues.
