An apparatus primarily for bird dispersal purposes at an airport has a remote control means provided for controlling operation of one or more sound emitting devices adapted to cause a detonation or emit a detonation-like sound at a required position or positions, e.g. in relation to an airport runway. The control is such that after a sound emission the device or each device is ready for further operation. Each device may consist of a combustion chamber having an outlet, the remote control means including a timer for initiating admission of fuel such as propane gas into the chamber for a pre-determined period followed by automatic ignition of the fuel/air mixture for detonation thereof. The remote control includes provision for selective operation of the devices at different positions, e.g. adjacent a runway, and also provision for selection of devices for operation at a particular runway in use or at other required locations, i.e., where there is more than one runway or location.

Apparatus primarily for bird dispersal purposes comprising at least one sound emitting device comprising a combustion chamber having an outlet opening thereto; remote control switch means; electrically operated valve means arranged to be brought into operation by the remote control switch means for admission of fuel into the combustion chamber for a pre-determined period, and electrically operated ignition means automatically operable for subsequent ignition of a mixture of the admitted fuel and air in the combustion chamber in obtaining explosive combustion of said mixture to effect detonation, the electrically operated valve means and the electrically operated ignition means being thereafter ready for further operation by the remote control switch means for obtaining further explosive detonation in the combustion chamber.
