Abstract
Abstract A seismic energy source comprises a plurality of inflatable chambers supported on heat conductive members adapted to be cooled by the flow therethrough of liquid in the medium in which the source is to operate. The sources are connected to a gas mixing and ignition chamber through a plurality of conduits of substantially equal length, preferably having diameters in the range 0.2 to 1.5 centimeters. Each chamber is associated with an individual exhaust conduit having different lengths and preferably having different diameters. Preferably no two of the lengths of the exhaust conduits are the same, and preferably no two of the diameters of the exhaust conduits are the same.
