...The popping of a balloon is not the standard or best way to measure an impulse response, but more sophisticated equipment was not allowed at Stonehenge. At a full-size replica of the monument at Maryhill, Washington state, however, Bruno and Rupert were able to use powerful loudspeakers and special test signals to get more accurate results.
Maryhill also has the advantage that it is complete, whereas some of the stones of Stonehenge have fallen or disappeared over the years. That makes a noticeable difference to the drum sounds convolved with Maryhill's impulse response: the more complete stone circle makes the sound echo for longer, with the extended reverberation being most noticeable after the last drum.
Over many decades, a sophisticated understanding of how to interpret impulse responses has been built up. For example, we now know how features within the impulse response, such as the time it takes for reverberations to die away, relate to peoples' perceptions of the nature of the sound. The hope is that by applying that expertise to ancient monuments such as Stonehenge, we can better appreciate their acoustical effects on our ancestors -and perhaps begin to answer the question whether these effects were the product of accident or design.

Stonehenge replica in Maryhill, Washington
By the dorm there is/was an open 6 “bay” (3 on each side) handball court. If you put a blasting cap in one of the end ones and touched it off, the whump would circle around a couple of times. More if you were stoned (so I was told).
So they figured out the acoustics, but have they figured out where they hid the weed?
Why do I have this total conviction the some people have waaaay too much time and too little real work to do?

Perhaps it was the venue for the world’s first “rock” concert!;)

Probably another one of Pelosi’s $500 million shovel ready stimulous projects!
wow. Thanks.
Good point, and we’ve just learned from some Dim Congressman (ironically named Bright) that Pelosi herself is shovel ready.
So, time travel *is* the answer! I knew it!
When they stood up a menhir which had fallen over, they found an inscription on the previously covered face, it turned out to be a transcription of *music*, and the tune, as it turned out, was the same as “Rainy Day Women #12 & 35”. Figures, ‘cause in England it rains a lot.
We never suspected you.
Like, dude, I'm hearin' the music!
Loons.
All that’s missing are the seashell headsets.
