Noise control refers to the methods and strategies used to reduce or manage unwanted sound in various environments. This can include techniques such as soundproofing, which involves using materials that absorb or block sound waves, and noise barriers, which are structures designed to shield areas from external noise sources. Effective noise control is important in settings like homes, offices, and schools to enhance comfort and productivity. It can also play a crucial role in urban planning, where managing noise pollution contributes to better quality of life for residents.
