FIELD: agriculture.
SUBSTANCE: invention relates to the field of fighting rodents and may be used in systems of physical protection of facilities against an intruder. The acoustic effect device comprises an acoustic radiator and a supercharger with an air moisturiser. To impact an intruder, a moistened following air flow is developed. An acoustic signal is sent towards the intruder via the moistened air flow.
EFFECT: invention provides for higher distance of pain acoustic effect at the intruder.
