Infrasound harassment.

Abstract. ‘Ultrasound and infrasound’ explains that humans can hear sounds with frequencies in the range of 20 Hz to around 17 kHz, but there is a wide ultrasound soundscape beyond this range. Bats, for example, are able to navigate and hunt using echolocation, generating ultrasounds and timing the delays until they hear the echoes, …A further method used is so-called ‘silent sound’ or infrasound. Just below the frequency of human hearing infrasound causes a hardly discernible vibration to be felt within one’s body such that the sound can actually be felt rather than heard.Dec 4, 2013 · A similar infrasound problem happened in my appartment building. I used a stethoscope on the walls to track the source. It was a centifugal fan in a neighbor's ventilation system. It had not been cleaned for years, and dust had accumulated inside in an asymetric pattern, causing an unbalance in the center of gravity of the rotating part. The human ears are capable of hearing sounds with frequencies as low as 20 Hz all the way up to 20,000 Hz (20 kHz). However, this range decreases with age, with most adults being unable to hear above 16 kHz. Sound at frequencies below 20 Hz, called “infrasound”, are ultra low frequencies that we cannot hear but can be felt as vibration.19-Apr-2017 ...
