Hint: To solve questions as such, we need to identify the source of noise and what noise is. Basically we can define noise as the sounds without any harmony. This will lead us to the solution for the problems stated in the question.

Complete answer:
Noise pollution is defined as the regular exposure to elevated sound levels which may lead to adverse human effects in human beings or other living organisms. As per the World Health Organization or WHO, the sound levels which are less than 70 dB do not cause any damage to the living organisms, no matter how much they are exposed to the sound. But we should know that exposure to more than 8 hours to constant noise beyond the level of 85 dB is very dangerous.

For instance, if we are working for 8 hours daily in a close proximity to a busy road or a highway, we are very likely to be exposed to traffic noise pollution which is around 85 dB.
One of the major sources of traffic pollution is Transportation. A large number of vehicles on the roads, airplanes flying over houses, the underground trains produce heavy noise. It is very difficult to get accustomed to these noises.

The high noise leads to the situation where a normal person loses the ability to hear properly.

Noise pollution can lead to many health related problems in which the most common one is Hearing loss. It can also lead to high blood pressure, heart diseases, sleep disturbances, etc. Even wildlife is largely affected and which is seen with change in their feeding pattern, hearing problems, communication problems, etc.
