1 mhz sound

6 Hz beat enhances all area of the brain within 10 minutes . 8 Hz and 25 Hz beats have no clearly responses while 40 Hz beat enhances the responses in frontal lobe. These brain responses can be used for brain modulation application to induce the brain activity in further studies.

At high volumes, infrasound can directly affect the human central nervous system, causing disorientation, anxiety, panic, bowel spasms, nausea, vomiting and eventually organ rupture or even death from prolonged exposure .28 Ara 2017

Humans can only hear sound waves between 20 and 20,000 Hz , but sound waves can still affect us below that threshold.

7 Hz infrasound (the frequency of the brain and the internal organs) can affect the human central nervous system and cause: general confusion . anxiety and panic. bowel spasms.

“Our bodies and minds are extremely sensitive to a wide range of frequencies in music and sounds in our environment.… Sound frequencies in music can also affect our hormones and are capable of triggering a release of endorphins, which act as our feel good chemicals that relieve stress and strengthen our immune system .”

Humans can generally sense sounds at frequencies between 20 and 20,000 cycles per second, or hertz (Hz)—although this range shrinks as a person ages. Prolonged exposure to loud noises within the audible range have long been known to cause hearing loss over time .
