Monaural beats

Monaural beats

Monaural beats are used for brainwave entrainment in which two tones which would be used binaural beats are played in each channel resulting in a stronger stimulus.^{[citation needed]} With monaural beats, the interference pattern that produces the beat is outside the brain so headphones are not required. They differ from isochronic tones because monaural beats are a sine wave pulse rather than entirely separate pulses of a single tone.
