So I guess treating a room with acoustical panels Will provide a benefit. This is news. So many great enthusiastic people have led me to rethink my position. I thank everyone for helping me overcome my fear of adopting a more liberal view about acoustical treatments.
Now if only someone could help me deal with Leaf blower noise throughout the day from neighbours who are too lazy to deal with lawn issues with a rake. And just why are we using leaf blowers in the middle of the summer when there’s no leaves? Because blades of grass somehow have taken over. Proliferating use of leaf blower noise is a serious problem. Ever noticed bird populations have declined quite a bit and a lot of it has to do with leaf blower noise throughout a community. Further if you have allergies they are probably a lot worse because of all the leaf blowers kicking up so many particles. I’d mention the environment because of the gas powered Leaf blower engines but people don’t care about the environment much anymore. They can't use mufflers because it would impact the flow of air and we wouldn't want that to happen.
