I suspect this is more of a coincidental feature of the stone circle and the music expert is presuming a little too much. How many similar structures do NOT have interesting acoustic properties? Very few, I suspect.
For example, the “whispering” gallery (galley?) in the dome of St. Paul’s in London is well know for it’s strange acoustic properties, but it was not one of the Christopher Wren’s goals when he designed it.
I think Huddersfield has driven driven the prof to spend too much time in Ibiza.
