A portable acoustic warning device which projects a specific acoustic waveform towards a target, creating a narrow beam of sound that is highly selective, minimising exposure to users and bystanders, whilst enabling a controlled dosage of sound to be applied to the target. The design of the device is tailored to this waveform thus achieving a very high degree of directivity. It is not intended for communicating verbal messages. This waveform achieves maximum intensity at the target whilst using a relatively low sound pressure level meaning that the exposure levels can be controlled to ensure they are within existing health and safety legislation. A laser range finder limits the sound level at the target to a pre-determined level. An integrated camera is used to aid aiming. Video footage is recorded with use along with the sound level at the target, exposure duration, time, date and GPS coordinates.
