Ok guys here is a good one for you lol. I play in our worship band at our church, and we have constant arguments between each half of the team, one says its too loud and the other says its not loud enough. Today they brought in a decibel meter and we measured at 109db. Now my amp is only on two and its not loud at all. I tried to explain to them that our actual volume is very low but its perceived to be higher because we have NO acoustic treatment what so ever, so all the sound is bouncing around and compounding over and over. Im not sure if anyone can point me to any reference material in which I can show them what im talking about and convince them to treat the room(unless im just completely wrong). I just know that when I built my studio and hit a snare in the room it made my ears bleed, it was unbearable. As soon as I treated the walls it didnt sound nearly as loug and was perfectly fine. Please let me know, thanks.
