Szynalski.com has a page discussing the 40hz/plaque removal.

Another tone generator that I've used -- https://mynoise.net/NoiseMachines/isochronicBrainwaveGenerat...

I like binaural beats, some give me an ASMR like effect (ASMR videos made with binaural backgrounds b work well for me too).

That is pretty nice, but i note that they don't reach up to 40hz.
