I collected references, supporting the hypothesis that binaural beats have an influence in our brain (see here).
I currently see two possibilities to possibly increase the (measurable) effect of binaural beats:
- What-ever brain wave doesn't have a fixed frequency but a range. Sweeping across the frequency band could be an improvement.
- Sweeping the volume from left to right.
Is this already researched?
EDIT 2: Sometimes (white, pink, brown) noise is mentioned to increase the effect. There might be a optimal signal-to-noise ratio...
EDIT: The frequency of the sweep shall be low. My focus lies on hitting your personal resonance frequency to increase the effect of binaural beats. As written in the linked post: This maximum declines as the carrier moves away from 440 Hz.
