If someone is trying to relax, a lower frequency might help them achieve a more calm and relaxed disposition.

For example, if a person is trying to concentrate, a higher frequency might help them focus better. Researchers believe that the entrainment triggers different states depending on the frequency range and type of sound used. These tones guide the dominant brain waves to enter a different frequency range that triggers changes in a person’s mental and emotional states. The sharp, distinctive pulsing sounds cause the brain to entrain or match the sound’s frequency.Īn isochronic tone helps the brain to entrain the pulsing of sound waves. Isochronic tones produce pulsating effects that come in the same frequency, separated by short intervals, much like the equally spaced beeping of an alarm clock. The beats stimulate specific areas of the brain, causing these areas to produce electrical impulses at the same frequency as the beat.

When you subject yourself to audio-visual stimulation, such as listening to isochronic tones, your brain will start to follow along in sync with the rhythm. Some people use isochronic tones, along with binaural and monaural beats, for brainwave entrainment purposes.īrain wave entrainment is a process that uses auditory stimuli to alter the brain waves. Isochronic tones refer to regular beats of a single tone that come on and off at evenly spaced intervals.
