 Ultrasound Rat & Mouse Repeller
What is Ultrasound?
Expressed in hertz, untrasonic sound is sound waves of 20,000 hertz
and above, or 20kHz (kilohertz). The Mouse & Rat Repeller automatically
sweeps a frequency of 30-6-kHz, which is above the hearing range
of humans and non-rodent pets such as dogs and cats:
Human hearing = up to 20,000 Hz
Cat & Dogs hearing = up to 27,000 Hz
Mouse and Rat Repeller = 30,000 - 60,000 Hz
Because of its high frequency, the sound emitted by the Mouse &
Rat Repeller behaves in a similar way to light, as opposed to, say,
the sound from a stereo. In this way, the ultrasound is reflected
by solid objects such as walls and doors, but will not penetrate
them to fill the rooms adjacent.
Rooms and buildings with hard surfaces (kitchens, conservatories,
sheds and greenhouses) are ideal environments in which to use the
Mouse & Rat Repeller. It can also be used in rooms with soft
furnishings, such as bedrooms and living rooms, but take care not
to obstruct the area in front of the unit. Rodents find the high
frequency sound distressing and will move to a less hostile environment.
