Infrasound and ultrasound - risks and means of protection

The human ear is exposed to a significant amount of various sounds and noises on a daily basis, over a wide spectral range extending beyond the frequency limits of human hearing, defined between 20 Hz and 20 kHz. Although our hearing aids transmit only frequencies between these limits to our brain, our organization is potentially subject to such frequencies.

Although these infrasound and ultrasound frequencies are not perceived by the ear, they can have an impact on our hearing.

This document aims to simply explain the nature of these frequencies and the environments we are generally exposed to, in order to discuss their potential dangers and finally provide some solutions to protect ourselves.
