Well, OK, then one final salvo. This weekend I took a GenRad 1565-B 
sound pressure level meter to the Groton School Chapel, which just happens
to have one of G. Donald Harrison's more famous "American Classic"
instruments in it. I played a few chords from just notable works as
the Bach D minor T&F, the G minor Fantasia and Fugue, some Dandrieau,
some Couperin, & the like. Using a registration consisting of the complete
Great principal chorus (principals 16', 8', 4', 2 2/3' 2', Fourniture V)
Plus a mojor portion of the Fulte chorus (bourdon 16', Cornet V), plus
the Cymbal IV, plus the complete reed chorus (Bombarde 16', trompette 8',
Clarion 4'), the complete pedal division, coupled to the Great, with all
reeds, thje maximum SPL I read in real chords was

	88 db SPL at the console (45 feet from the pipes)

I, and probably few others, will continue to reproduce it at the 
original levels, when possible. These are seldom in excess of 88 dB.

If you find difficulty with this figure, please don't bitch to me. Try the
NBS, who is responsible for the calibration of this instrument.

Enough, OK?
