When two waves interact producing a "cancelling" effect as seen by noise reducing headsets, what kinematic energy is associate with the effected medium immediately near the cancellation point(standing wave)? Furthermore, in an ideal setting, would it be possible to instantly reorient the surrounding local environment to release a high energy coherently combined and vectored event? Stated in better terms, a seemingly undisturbed point that is a neutralized(stabilized?) by extreme opposite and equal input energies releasing a combined impulse-like output shortly after an instantaneous reconfiguration of the local environment. For simplicity's sake waves on water can be used to answer the question. [Edit] for a little background i wanted to include what initiated my curiosity: could an effect like this be used in either a practical or ideal(allowing instant reconfiguration and perfect interactions) setting to produce a high energy ultra-fast pulse from things like laser-pumped crystals and/or solids(for a highly disruptive result)?
