  • Seismic pneumatic energy source with flap valves for attenuation of bubble pulse amplitude and reduction of period of bubble oscillation
    Patent number: 4006794
    Abstract: A method for decreasing the amplitude and period of bubble pulses following a primary seismic energy pulse comprises generating an expanding air bubble around a body and preventing the air bubble from contracting into the body for attenuating the sudden contraction and collapse of the air bubble, and two valve devices on a closed cylinder for carrying out the latter method resulting in minimizing bubble effect and the size of the bubble for decreasing amplitude and period of bubble oscillation for providing a clear, well-defined acoustical wave.
