Things That Go Bump in the Night

By Deane Barker on April 14, 2004

Every night, five mysterious thuds wake up neighborhood: On the heels of Joe’s post about ghosts in the machines in Sciliy, I found this over at Boing Boing.

It’s been six months since the residents of Manor Green Road in London have had an uninterrupted night’s sleep. “[T]hey have been hearing five repeated thuds in the middle of the night and cannot trace the source. Double-glazed windows and ear plugs have been no match for the tumult.”

Reading the article it links to, it makes me wonder why they couldn’t just triangulate the noise. Couldn’t you rig up some microphones, record through the night at a different place every night for a week, then pinpoint the noise based on the direction relative to the microphone’s position?

Is my reasoning scientifically accurate here?



  1. Is my reasoning scientifically accurate here?

    close- set up 3 or more microphones and record simultaneously for just one night, then calculate the sound’s source based on the time offset from each microphone… very simple but needs each recording to be precisely syncronised.

    I would bring all 3 recording devices to the same place, start them recording, make a ‘clap’ noise, then, with the devices still recording, take each one to its final vantage point.
