Low frequency noise (LFN) is generally defined on the Common Octave Bands as 250 hertz (Hz) or less . You might know it better as that chest-rattling thump of the bass from a car driving past with its music cranked. You can’t really make out the song, but you can feel the beat in your chest.

It turns out that the resonant frequency of much of the human body is also close to 19 Hz . Vibrations in Tandy’s chest led to breathing difficulties, which in turn brought about the feeling of dread and the cold sweat.

The key here is frequency: 19hz is in the range known as infrasound, below the range of human hearing , which begins at 20hz.15 Eki 2003

The two test an urban legend that claims that there is frequency around 19 Hz that can produce feelings of discomfort, dread and, yes, even fear. But the thing is, 19 Hz is below the threshold of human hearing, so these feelings are produced without anyone being able to hear the note .
Read moreWhat is the difference between high and low sounds?
The distance between the peaks of the waves is called the wavelength. High–pitched sounds have short wavelengths, which means that the peaks are close together. Low–pitched sounds have longer wavelengths, so the peaks are more spread out .
Read moreWhat is considered high and low frequency?
How are sounds measured? Frequency is measured in hertz (Hz) [hurts]. A low- frequency sound is about 500 Hz or lower. A high- frequency sound is about 2,000 Hz and higher .
Read moreIs 20hz high-frequency?
High frequencies produce more oscillations. The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz . Frequencies above 20,000 Hz are known as ultrasound.3 Tem 2018
