Space Mountain has a new off-board audio system called “Starry-O-Phonic Sound.” I rode the Peoplemover (:happy:!!) last night and heard music playing inside SM… the ride wasn’t letting guests on at the time so I thought maybe there was a private party going on, but apparently this music is part of a new audio feature.
Space Mountain is now running with it’s brand new audio system, dubbed ‘Starry-O-Phonic Sound’. The addition of the audio now completes the major 2009 refurbishment that added new storyline elements, new lighting and darkening effects, updated loading area and queue, new queue interactive games and an on-ride photo system.
Unlike Rock ‘n’ RollerCoaster or Space Mountain in Disneyland or Paris, which use on-board speakers mounted in the train, Space Mountain uses 60 speakers installed “off-board” on the sides of the track. Sound effects and music are timed to play as each train passes. The soundtrack was written specifically for the Magic Kingdom’s mountain by composer Mike Brassell.
The full article can be found here - it includes a review of the musical score and sound effects, and there is a youtube clip at the bottom of the page that lets you listen to the whole ride with the new audio.
