Over thirty years ago I was involved with a study to check the effect of
continuous white noise on rats.
Over three generations the females became skinny and the male rats became
fat. The experiment was terminated when the most interesting result may
have presented themselves. Either the females or the males had fertility
problems. The number of pups was significantly less. The observation was
never published.
In principle any frequency can be used to entrain or effect other
frequencies. The
basic model of Correlational Opponent Processing (http://turn.to/ai) suggest
the brain uses wavelets to process and store information.
The frequency associated with consciousness is 40 hertz. Therefore a low
frequency
sound could have significant effects on the nervous system.
