WebWhen conducting research of the impact of infrasound on the environment, it was established that infrasound waves may cause the feeling of fear and anxiety. Infrasound of 120 dB (and stronger) is very dangerous to the human organism; in addition, infrasound waves may ruin or damage the constructions of buildings. At the WebInfrasound, in its popular definition as sound below a frequency of 20 Hz, is clearly audible, the hearing threshold having been measured down to 1.5 Hz. The popular concept that sound below 20 Hz is inaudible is not correct. Sources of infrasound are in the range from very low-frequency atmospheric fluctuations up into the lower audio frequencies.
