Do soundproof curtains really work?
2025-11-04
Your windows have already reduced outdoor noise to 40 decibels, but you still find it noisy. Since you can't modify or add more windows, and you want to further reduce it by 5 to 8 decibels (low frequencies might be around 5 decibels, high frequencies close to 10 decibels), then the only solution is to install soundproof curtains. Because curtains can only block...
