Thank you, thank you, beforehand.
This whole thing is about sound so...
First I want to find out, if I have a sound source like a speaker. I want to figure out how far it travels and how much ...I guess vibratory energy it looses due to (I guess it would be called attenution) length of travel in air, then through other material.
I can find like the material stuff, but I don't know where to start really....
As you can see I am a bit confused so maybe some can help me out here...
Because I can never tell if sound coming from my APT is heard elsewhere, and I hate being anxious all the time but I hate to disturb people too so, If I can figure it all out I can feel better about it!
