Earwormy

Which one is better? Pick blind.

Four tracks, two masters each. One is Earwormy, the other a human's master. Both play at the same loudness and their positions are random for every listener. Just trust your ears.

  1. 1Use headphones or good speakers. Set a comfortable volume and keep it the same for the whole test.
  2. 2Switch between A and B as often as you like. The track keeps playing where it was. On a keyboard: 1 and 2, space to play/stop.
  3. 3Pick the one you would release. If you can't hear a difference, you can say that too.
Takes about 4 minutes.
