Abstract:
A method of seismic exploration comprising:(a) exciting at least one seismic source having a first signal at a source location on the surface of the earth thereby generating seismic waves traveling into the earth and reflecting from formations therein; (b) operating a speaker system associated with and in proximity to the at least one seismic source, said acoustic source having a second signal for generating acoustic waves propagating above the surface of the earth; (c) placing at least one seismic detector at at least one receiver location on or in proximity to the surface of the earth for receiving airborne noise generated by the at lease one seismic source, said reflections of seismic waves, and said acoustic waves, and generating a third signal in response thereto, said at least one receiver location spaced apart from said at least one source location; (d) placing at least one acoustic sensor in proximity to said at least one receiver location for receiving said acoustic waves and said airborne noise, and producing a fourth signal in response thereto; and (e) processing said third and fourth signals to provide a processed signal substantially comprising reflections of said seismic waves.
