Gamma band

40 Hz Gamma

Gamma activity around 40 Hz is associated in the literature with attention and the binding of sensory information. We deliver it as a 40 Hz binaural differential over a warm ambient bed.

What the evidence says

Gamma and cognition is an active research area, but the effect of listening to a 40 Hz beat is still being established, not settled. We do not make clinical claims.

Much of the strongest 40 Hz work uses direct sensory stimulation in lab settings, not consumer audio. Treat a 40 Hz session as a focus aid, not a treatment.

How we measure it

Carrier 200 Hz, right channel 240 Hz, giving a clean 40 Hz differential. Spectral centroid and evolution are published per session.
