Binaural beats
Binaural beats are perceived when slightly different tones are presented separately to each ear. The listener’s auditory system detects a perceived beat-like difference. Headphones are generally central to the intended setup.
Isochronic and monaural tones
Isochronic tones use regularly pulsed sound, while monaural beats combine tones before they reach the ears. The experience and technical requirements differ from binaural listening.
Why the distinction matters
A study of one format cannot automatically validate another. Carrier frequency, modulation depth, volume, background sound, and session length may change the outcome. A product should disclose enough for buyers to understand what they are receiving.
The Memory Wave context
The public materials reviewed for this site emphasize sound and gamma activity but do not provide a full technical sheet. That limits precise comparison with research protocols.
