I've had a couple of these machines and they proved most useful when trying to sleep at Burning Man's regional events in Australia
You can probably guess how the soothing drones from a couple of Buddha Machines will interact and help with sleep when confronted with multiple sound systems shaking the earth and vibrating air molecules.
One of the best lessons my father taught me was to put on a radio when nights were too noisy to sleep.
The
FM3 loops provided a sound to focus on, rather than having my ear
wandering the paddock and becoming annoyed by the sound systems that
drift in and out of time and gratingly never agree on a musical key.
It was surprising how well my partner and I slept as the ground rumbled and people partied through the night.
I ended up buying one for my mother out-law and she used it to sleep on her travels.
The
latter editions of the FM3 Buddha Machine had the advantage of being
louder and adjusting pitch, but mine didn't seem as robust as the
earlier model.
I'm hoping to buy a replacement whenever they are stocked in Australia again.
