Evaluation of overall sound quality


Thank you for your time ! Please read carefully the following information, even though you are used to doing such tests !

For each pair of recordings below select one button depending on your preference about the overall quality of the two sounds:

  • If the left recording is much better than the right one, select the most left button (-3).
  • If the left recording is better than the right one, select the second button (-2).
  • If the left recording is slightly better than the right one, select the third button (-1).
  • If the two recordings are about the same, select the middle button (0).

... and the same on the other way.


Recommendations

  • If there is any technical problem with one sound, select Prob.
  • If if you think there is a difference of loudness such as you can't properly evaluate the pairs, please select also Prob.
  • Use absolutely headphones or earphones.
  • Verify that the sound level is loud enough to hear the sound details properly.
  • Do the test in a quiet place.
  • Take the time to listen !
  • Do not try to find a repetition or order in the presented sounds, there is none, their order is randomized.
