Thanks for pointing that out Johnk. I noticed it too, but I am not use to thinking in logarithmic terms.

Edit: I need to learn to read more carefully. First tiem 'round I assumed they did the subtraction in the formula.

OK, I built the calculator in Excell (minus rounding 'cause I know how you audiophiles like accuracy \:\) ) and it works.

So, where do I plug in the room adjustment? Where the formula adjusts for headroom? Hmm... need a sound engineer's help here. Now where would we find one of those??

Edit: ok, I see how the formula works now. Add 5 to sensitivity or take 5 off of listener spl or headroom, its all the same.

Maybe I should stick to simpler things at this time of night like cleaning my tub.
