How do curtains help reduce the loudness of sound?

Curtains absorb sound waves rather than reflecting them, reducing reverberation and echoes. The soft fabric prevents sound energy from bouncing back into the room, lowering the overall loudness. Related Questions: Why does sound require a medium to travel? What is the effect of humidity on the speed of sound? What is the difference between audible, … Read more
