I apologize, I should have been more specific. You can contact Brad Scott this email:
brad@wildbranch.org He will give you names and such of modern scientists in the field of recording frequencies into natural objects. Mr. Scott often uses such examples in his work.....He may take awhile to reply seeing as he is in Israel giving a tour at present but he will get back to you as swiftly as possible.
