I assume Dan is answering, "Exactly," only to my question about
comparable levels, not to rule by thumb. :-) One place I remembering
this 10mV/Pa figure was in a Mic FAQ that Michael Cooper compiled
for the DATHeads list from various sources. Of course, nature
recordists often encounter lower sound levels than the concert tapers
who accounted for a good percentage of subscribers on that list. Rob
