. LISTENING TEST .

Ouh it is such a bad day for me in my class, i had to go early and rushing because i am already late! Today we got the listening test, just the preparation to us for having the Listening test on 25 th January. It was quiet taff and i really disapointed with my marks. I only get 12/15 and 10/15 for both test, and dont got the higher marks :( I am dont concentrated and listened carefully. I hope that i will past with the flying colours on my listening test so that it will help me on my Final Exam. I hope so....

What we do here

Loudspeakers are not perfect. At high driving level, they add distortion to the music you play, reducing the quality of sound reproduction.

Whether you can hear the distortion depends on many factors - like the actual loudspeaker, the music you play, the loudness level, and the training of the listener.

We provide an interactive listening test where we determine the audibility of nonlinear distortion for different music signals and different speakers.  

Auralizing Distortion

Normally, when playing music, you cannot easily separate the linear signal (what your loudspeaker is supposed to play) from the distortion. With a simulation, we can do that - and then mix it together again, but with the distortion enhanced or attenuated.

This way, we can make the distortion artificially more or less audible. 

For the test you should listen with a "perfect speaker" - headphones are a good approximation, since they add almost no distortion on their own.

Your Benefits

You get a subjective impression how different kinds of loudspeaker distortion sound. If you know this, you are able to detect them much more easily. 

Immediately after the test, you see your results - and you may compare your hearing capabilities with other listeners.

You also get a feeling what kind of music or test signal is critical, or what kind of stimulus can be played on every speaker without hearing a difference.

Finally, when you take the test again, you will most likely notice you find lower thresholds - your ear has been trained.

Our Benefits

We collect the data - anonymously of course - and aggregate statistics that explain the mechanisms of hearing distortion. The basic statistics are immediately available on the web site.
