Скачать или смотреть You need to know about window noise and STC ratings!

A lot of noise comes into our homes through the windows. Especially low-frequency noise like vehicle engines, leaf blowers, and street construction. Don't waste money on the wrong "solution" that doesn't work. Beware of the Amazon Affiliate sites that promote "soundproof curtains" (so they can make a commission)! And don't spend a lot of money on window inserts until you're sure that your window is actually the problem, and not the walls.

Learn about STC and how mass (density) helps to reduce low-frequency noise. And discover which solutions might get the best results.
