<P> Sensurround is the brand name for a process developed by Cerwin - Vega in conjunction with Universal Studios to enhance the audio experience during film screenings , specifically for the 1974 film Earthquake . The process was intended for subsequent use and was adopted for four more films , Midway ( 1976 ) , Rollercoaster ( 1977 ) , the theatrical version of Saga of a Star World ( 1978 ) , the Battlestar Galactica pilot , as well as the compilation film Mission Galactica : The Cylon Attack ( 1979 ) . Sensurround worked by adding extended - range bass for sound effects . The low - frequency sounds were more felt than heard , providing a vivid complement to onscreen depictions of earth tremors , bomber formations , and amusement park rides . The overall trend toward `` multiplex '' cinema structures presented challenges that made Sensurround impractical as a permanent feature of cinema . </P>
