    Not in my wheelhouse, but here's a shot:

    Clearly 330 Hz (E4) and 495 Hz (B4, which is 50% higher) are heard.

    The third frequency perceived is either 165 Hz (E3, 1/2 of E4 and 1/3 of B4) -- and that's my first guess -- or 990 Hz (B5, 3x E4 and 2x B4).

    Let me know if you would, please.
