Facts about resonance sound

Resonance sound waves range approximately between 30 - 500 Hz. The sound is clearly audible and is easily transmitted throughout the frame structure of a house.

In connection with discussions regarding the adverse effect low frequency sound waves might have on human beings where cases of for instance depression have been reported, this debate is only relevant for purely subsonic sound waves with frequencies ranging below what man can hear (less than 30 Hz).

Topo Stop R100 resonance model works with a frequency range between 80-100 Hz. In conjunction with ultrasonic pest control devices the disturbing sound waves will penetrate all closed as well as open spaces in a building. The CO-use of both resonance and ultrasonic sound has proven to be very effective in severe cases of pest infestation.
