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 sound frequency makes you hallucinate?
The standing waves/hallucinations arise when flicker frequencies are approximately twice the natural frequency of the damped oscillations in the neural dynamics (Rule et al., 2011). The resonant frequency of simple cells in the primary visual cortex of cat typically peaks near 5 Hz (Movshon et al., 1978).

The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz . This is also the resonant frequency of the body’s organs.
Read moreCan you hear 19 Hz?
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
Read moreIs 20 Hz high or low-frequency?
Sound at 20-200 Hz is called low-frequency sound, while for sound below 20 Hz the term infrasound is used.
Read moreCan sonic waves hurt you?
Yes, it can ! Sound can kill you in multiple ways. If we’re talking about sounds within the human hearing frequency range (between 20 and 20,000 Hz), high-intensity sounds above 150 decibels can burst your eardrums, while sounds above 185 dB can impact your inner organs and cause death.
Read moreWhat is intra sound?
infrasonics, vibrational or stress waves in elastic media, having a frequency below those of sound waves that can be detected by the human ear —i.e., below 20 hertz. The range of frequencies extends down to geologic vibrations that complete one cycle in 100 seconds or longer.
