Question About Low Frequency Sounds

Onhwy61,

The information about brain waves are true. They are the typical brain activity as measured on an EEG (electroencephalogram), and often used in sleep studies.
Delta waves are found in the deepest stages of sleep, while beta waves are much higher in frequency (relatively) and seen in REM sleep.

What their implications on music is beyond me.

Doc

If you look here at the table of contents (left column under No 2) you can review the course I've been taking on brain frequency training. But after two years at I still can't get off 1hz. The doc says I'm the first person he's seen with a resonant frequency of 1hz. I'm a good sleeper.

Hope to see ya in class

zzzzzzzz
I remain,

Our brains "VIBRATE?"

Here's a link to a story on the BBC website about research regarding infrasonics and church organs. It concludes that low frequency sounds from church organs are responsible for a wide range of emotional responses that people may feel at religious ceremonies.

You guys understand that the EEG measures electrical wave patterns, not physical motion. Our bodies do vibrate, and the frequencies have more to do with the heart rate and the resonances of the different body cavities and chambers. The sound production of the voice is a very interesting science which is well described back to the 70's. I recall an article in Science back to that era when I was a serious voice student although I cannot quote you the date. The reason we feel different frquencies in different parts of our bodies have to do with these resonances, not to be confused with the chemo-electrical output of cental nervous and muscular tissues .
