you are 100% incorrect......Call local law enforcement and ask if you can disturb the peace at anytime of the day.not just if sound exceeds a certian decibel.... Anytime you have a noise complaint and local law enforcement is sent out they will ask you to tone it down...............there is no such thing as blast as loud as you want during certain hours.....you can disturb the peace at anytime during the day.....
I did look up the WA laws on this subject.
Here is what I understand. If I wanted to run my lawn mower during the afternoon I am totally within my rights to do so. Or lets say I wanted to practice playing the piano at 3pm? You are telling me I cannot do either if somebody that lives close to me doesn't want to hear it? Furthermore, I am not sure how playing pool could ever be described as disturbing the peace.
