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.
- 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.
- Absolutely use 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.
