System and method for generating and directing very loud sounds
First Claim
1. A system for producing a sound wave, comprising:
- at least one detonation tube apparatus, comprising;
at least one detonation tube having a closed end and an open end;
at least one detonator having at least one spark initiator and an ignition point substantially located at the at least one spark initiator; and
a fuel mixture supply subsystem for supplying a fuel-oxidant mixture to said at least one detonator, said fuel-oxidant mixture comprising a fuel and an oxidant, said fuel mixture supply subsystem maintaining a predetermined mass ratio of said fuel versus said oxidant and maintaining a predetermined flow rate of said fuel-oxidant mixture to achieve detonation characteristics, said detonation characteristics depending on length and diameter characteristics of said at least one detonator, said ignition point being positioned within said at least one detonator such that said fuel-oxidant mixture flows through said ignition point into said at least one detonation tube via the closed end; and
at least one timing control mechanism for controlling the timing of said at least one spark initiator, said at least one spark initiator initiating at least one spark within said at least one detonator at said ignition point while said fuel-oxidant mixture is flowing at said predetermined flow rate through said ignition point of said at least one detonator thereby producing a detonation impulse at said ignition point that propagates into said closed end of said at least one detonation tube thereby initiating a detonation wave at the closed end of said at least one detonation tube, said detonation wave propagating the length of said at least one detonation tube and exiting the open end of said at least one detonation tube as a sound wave.

Abstract
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.
