According to recent studies, your brain learns and expresses fear at a certain brainwave frequency, and changing the frequency can change the feeling. Researchers found that the brainwave frequency of fear is four cycles per second , or 4 hertz.
Read moreWhat sound is 7hz?
Especially dangerous is infrasound at the frequency of 7 Hz, since this sound, generating frequencies, close to characteristic frequencies of the organs of our body, may disturb the heart or brain activity. Machines, natural sources storms, earthquakes, hurricanes, etc. generate infrasound.
Read moreCan infrasound make you sick?
Symptoms resulting from exposure to infrasound can include fatigue, headache, nausea, concentration difficul ties, disorientation, seasickness, digestive disorders, cough, vision problems and dizziness .”
Read moreCan infrasound make you crazy?
One study has suggested that infrasound may cause feelings of awe or fear in humans . It has also been suggested that since it is not consciously perceived, it may make people feel vaguely that odd or supernatural events are taking place.
Read moreWhat is infrasound used for?
The majority of the sound from volcanoes is low frequency (below 20 Hz, the threshold of human hearing) and is termed infrasound. Recent research has demonstrated how infrasound can be used to detect, locate, characterize, and quantify volcanic eruptions , providing a valuable tool for volcano monitoring.
Read moreHow does infrasound affect humans?
There is no agreement about the biological activity of infrasound. Reported effects include those on the inner ear, vertigo, imbalance, etc.; intolerable sensations, incapacitation, disorientation, nausea, vomiting, and bowel spasm; and resonances in inner organs, such as the heart.
Read moreIs 10 Hz a low frequency?
The range from 10Hz to 100Hz may be considered as the low frequency region , with a possible extension by an octave at each end. There is no need to consider infrasound as a “special case”. However, audible sounds at the lowest frequencies will be at a high decibel level (Table I).
