natural slap echo OT OT OT....

[Ian Fritz]

Sure -- it depends on the details of the geometry. Suppose you snap your
finger right next to your ear. The direct sound will be stronger than the
echo. But if you hold your hand straight out in front of you I think the
echo could be stronger... depending on how big the dome is, how well it
reflects and refocuses, etc.
