Answer:

1. Noise pollution, also known as environmental noise or sound pollution, is the propagation of noise with ranging impacts on the activity of human or animal life, most of them harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems

2. Noise level is measured in decibels (dB). The louder the noise, the higher the decibels. Decibels can be adjusted to human hearing. Noise level is thus described in decibels A (dBA)

3. Insulation measures are some of the primary and most practical ways to reduce noise pollution at home. It's an art of soundproofing, which helps in blocking the sound vibrations and noise. By improving insulation, it means installing soundproofing materials on the walls, ceiling, and even on the floor.

4. Noise pollution is defined as unwanted sounds that disrupt normal sound in the environment. Noise pollution often emanates from railroads, road traffic, aircraft, loud music, construction sites, and industrial activities.

5. Some of the ways to control noise pollution are as follows: (1) Control at Receiver's End (2) Suppression of Noise at Source (3) Acoustic Zoning (4) Sound Insulation at Construction Stages (5) Planting of Trees (6) Legislative Measures
