I had a similar thing with the binaural beats, after listening to them and the noise stopped, a continuation of a high pulsing sound seemed to linger on in my hearing.
I'm guessing it could be an after sound.
It's similar to looking at something for a long length of time and then looking away, you can see an outline of the image still in your focal plane.Except with this its with sound, not light


sometimes it can just be that you've had the volume up to loud.,....
