Instructions (read it first!!):
To see the results of the experiment, go here.
This perceptual test wants to be BRIEF, is why this presentation is BRIEF. For any question, just ask to: firstname.lastname@example.org.
The testing sounds are composed by blocs of two concatenated tones (a reference constant tone and a changing tone). The changing tone increases or decreases respect to the constant one. You will listen both concatenated and you will notice that easily.
Steps to follow:
Important recommendation: when you perceive what Q.I suggests, push the pause of the audio player in order to note down that second in the form.
- Answer to some context questions. Don't worry, I will not know who you are as this information is anonymous.
- Start the perception test:
- Read the question I (Q.I) before listening the sound. Be sure to understand what to search in the test sound.
- Listen to the sound.
- Answer the questions: question 1 (Q.I:"In which second did you started to perceive the two sounds as equal/different?") and answer the question 2 (Q.II:"In which direction was moving the second tone respect to the first?"). Those questions are always the same. You only need to take care if we ask you if they are equal or different.
- Do the same for the following sounds. Don't worry, there are only 8 sounds. It will take you less than 5 minutes to do the test.
- Once you have finished, don't forget to push the "Submit" button.
Finally, do NOT use speakers (is why is disabled the option in the questionnaire). Use headphones or earplugs.
