Electronic Realism in Disneyland

Sound effects liven scenic make-believe at mammoth park

WHETHER you want a rocket trip to the moon or a riverboat ride through the African jungle, you can find it in Disneyland, the super dream-and-play area created by the famous Walt Disney in Anaheim, California.

But more than a land of fun and fantasy, Disneyland has proven to be a vast laboratory and workshop where engineers and technicians have let their imaginations run wild in creating new equipment and startling visual and sound effects.

The sky was the limit in setting up Disneyland, and hundreds of specialists from such companies as Altec Lansing, Ralke, Berger Electric, Graybar Electric, etc., combined their talents to create illusions of sight and sound.

One hundred and sixty acres of flat, sandy ground were transformed into an intricate terrain of make-believe mountains, valleys, rivers, lakes, and forests. Artists, architects, earth-movers, builders, studio technicians, and electronics men teamed up to change a wasteland into the many little worlds that comprise Disneyland. These include: Adventureland, Fantasy-land, Frontierland, and Tomorrowland.

The sound installation, made by Altec, simulates the noises of dozens of beasts and birds that inhabit the banks of the jungle rivers. Prerecorded tapes are the storehouse of such sounds.

In the Adventureland control room, trumpeting elephants, roaring lions and rhinos, chattering monkeys—as well as the beating of native drums—originate from a bank of tape players. These machines play continuously a tape of any desired sound, repeating it at 10-second intervals. Operating in this manner, the tape machines repeat their messages 4320 times daily.

Finding the sounds to go on these tapes was a job in itself. It required months of searching through the sound track morgues of movie studios, broadcast stations, and universities.

Seventy-four separate loudspeaker systems, each carefully camouflaged beside animals and in the trees, reproduce the sounds. Six miles of cable connect these speakers to power amplifiers.

One difficult problem encountered was how to move the sound of birds that were supposed to be flying from one spot to another. Complete realism was required; the system had to do the job without the customary relay clicking and time delay switching. Invented solely for this task; was a unique unit dubbed a “rotation” audio fader.” This device transfers the bird calls from one set of speakers to another so neatly that visitors to Adventure-land swear they actually see the non-existent birds flying in the dense foliage. All other sounds in Disneyland blend into their surroundings so well that it is impossible to identify them as being artificially produced. The myriad of voices, music, and background sound is so vital to the operation and success of Disneyland that a full-time sound crew has been hired to stand by constantly to service the equipment.—John A. Norman.
