Izzy I have a book I purchased at Cold Harbor last year on Acoustic Shadows.  Called of all things Acoustic Shadow.  I cannot remember the name of the author right now and the book is in my car.  It cost about 25 dollars .  I have enjoyed reading it.  It was written by a  physics teacher so explains what causes the shadow.
