Question

how to decrease sound pollution of noise in our environment?

Answer 1

Do you mean in a building? Sound insulation maybe?

Answer 2

I don't quite understand what you mean. Do you mean in the city, in your house..?

Answer 3

I mean in the building :)

Answer 4

Yeah, you'd use sound insulation; you can get like foam and stuff that absorbs the sound.

Answer 5

Foam ridged objects, cones or squares on walls to redirect and absorb sound. Thick carpeting for more absorption. Those are a small amount of things you can do to a pre-built room. There is many other ways to design walls, ceiling, and flooring if the building has yet to be built.

Answer 6

Recycle sound, it decreases pollution.
