Monaural Beats The underrated entrainment method

Monaural beats are the quietest story in brainwave entrainment. Like binaural beats, they're created from two slightly different frequencies — but unlike binaural beats, the two tones are combined before they reach your ears, producing a single audible beat in the physical audio signal itself.

When a 200 Hz tone and a 210 Hz tone are mixed together, the resulting waveform pulses at 10 Hz in the air. Your brain doesn't have to synthesize the beat — it's already there, hitting both ears simultaneously as a real acoustic phenomenon. That makes monaural beats work through any speaker, headphones, or earbuds equally well.

Monaural beats sit in an interesting middle ground. A 2005 Schwarz and Taylor study published in the International Journal of Psychophysiology compared brain responses to binaural, monaural, and isochronic beats across a range of frequencies — and found that monaural beats produced more pronounced cortical responses than binaural beats at all frequencies tested.

Because the beat is present in the acoustic signal itself (rather than synthesized in the brainstem from two separate inputs), monaural beats may produce a cleaner, stronger entrainment stimulus than binaural. They're less studied than binaural beats overall, but the research that exists tends to favor them for listeners who find binaural beats ineffective.

Arkhitec's monaural library covers every major brainwave band with 26 carefully engineered presets. Delta monaural (0.5–4 Hz) for sleep, layered beneath soundscapes designed to complement the low-frequency pulse. Theta monaural (4–8 Hz) for deep relaxation and meditation. Alpha monaural (8–13 Hz) for calm focus. Beta (13–30 Hz) for concentration.

Because monaural beats work through speakers, they're ideal for situations where headphones aren't practical — bedtime with a partner, open-plan offices, or ambient background audio in a shared space. Every preset includes the same tested entrainment ramps as Arkhitec's binaural library, and every one can be layered beneath a soundscape in the 7-layer mixer.
