Wow. The note here is B 1(double bass B) tuned -012. If you can play B 1 on a 427.63 hertz instrument, you would get 60 hertz. Your phone can play it, but for sine, please turn UP the volume.

That sounds like the mains hum in North America

What a peace. This is how majority of electrical devices sounds like

I have had the hum in my ears which is humming coming from an unknown source and this blocks it
