Dustin Curtis posts on Disney's sound system.
"To get the original audio system at Disney World to work, engineers simply attached large speakers to several hundred light-posts randomly scattered throughout the park. ... [T]here is actually a minor flaw with this system. Because the speakers are placed on arbitrarily-positioned light-posts throughout the park, the volume of the music slightly fluctuates as visitors walk along pathways. As they get closer to a speaker, the music gets louder, and as they walk away, it gets quieter."
Although no one complained about this, Disney re-engineered the park's sound.
"Today, as you walk through Disney World, the volume of the ambient music does not change. Ever. More than 15,000 speakers have been positioned using complex algorithms to ensure that the sound plays within a range of just a couple decibels throughout the entire park. It is quite a technical feat acoustically, electrically, and mathematically."
