Abstract
Abstract Noise making apparatus for protecting crops from wildlife comprises a combustion chamber. A gas feeding device supplies explosive gases to the combustion chamber. A sparking device in the combustion chamber explodes the gases. A spark control device ignites the sparking device when the pressure of gas in the combustion chamber reaches a predetermined level.
