Is there a way to TEST EARPIECE volume?

[tivoboy]

my new 3gs, seems to have pretty LOW earpiece volume? I pretty much have it ALL the way up on every call, even in relatively low noise environments.

Is there a way to TEST this, and/or to increase it further?

Yeah, I seem to be having the same issue here too. Even in a quiet room, the earpiece isn't very loud at max
