Topic about how a trumpet resonates / distance / Old Post

[Greg Massey]

Does anyone remember the Pass topic on how trumpets resonates over other calls on the forum? It showed the difference in how a trumpet could be heard further than any other calls ... If someone has this pass post or can share the post topic name i would appreciate the help..  I think it even has the sound wave notes or something similar in that post ... thanks for the help...

I remember it but don't remember what the title was or anything like that.
