Sensurround

Where was all the rich high-fidelity we’ve come to expect from Sensurround electronics?

Accompanied by an oceanic World Music-style soundscape, the videos offer a Sensurround soak in the vitality and variety of diaspora as the museum envisions it.

It’s still a minor scandal among connoisseurs that in 1974 the “Sensurround” gimmick used in “Earthquake” beat out Walter Murch’s far more subtle and ingenious work using silence and shifting dynamics on Francis Ford Coppola’s “The Conversation.”

Underneath the birdsong and the buzzing of insects — Alexandr Dudarev’s soundscape is an irreplaceable part of the film’s immersive, almost Sensurround effect — there is the rumble of far-off traffic.

In 1974, the disaster movie “Earthquake” was released by Universal Pictures in “Sensurround,” which bombarded the audience with low-frequency sound waves during the quake scenes.
