1000 HZ - Brain Healing Frequency - Cerebral Neurons - Healing Frequencies

The tone at 1000 Hz was formerly used to calibrate audio equipment because it is at the center of what humans hear. It also seems to have a modulating effect on the brain center, influencing cerebral neurons.

Other researchers believe that the 1000 Hz in the high gamma range has a healing effect on the body. The frequency used here should be listened to through loudspeakers.
