An improved system and method for controlling and directing sound waves is provided. A fuel-oxidant mixture is supplied to at least one detonator having at least one spark initiator. The fuel-oxidant mixture flows through the at least one detonator and into the closed end of at least one detonation tube also having an open end. The timing at least one spark initiator is controlled to initiate at least one spark within the at least one detonator while the fuel-oxidant mixture is flowing through the at least one detonator thereby initiating a detonation wave at the closed end of the at least one detonation tube. The detonation wave propagates the length of the at least one detonation tube and exits the open end of the at least one detonation tube as a sound wave. When multiple detonation tubes are detonated with controlled timing, the resulting sound waves are directed to a desired location. Sound waves can be directed from groups of detonation tubes and from a sparse array of detonation tubes.
