You may be onto something!

I suggest you E-Mail contact Dominic Stanziale in Italy regarding said
noise reduction phenomenon:

Domenic and I have had many conversations on theatre acoustics in Italy, and
knowing his general interest in the matters of noise, noise measurements and
theaters in Italy, he may be able to bring forth (make field measurements)
some quantitative information on the subject (noise reduction of ancient
outdoor venue perimeters). His major responsibility is factory
and construction noise, but maybe there is a connection....
