The Adjustment/Satisfaction Test (A/ST)



As media consumption is heading towards high degrees of content personalization, there is a growing need to assess the perceptual performance of these developments. The Adjustment/Satisfaction Test (A/ST) is a perceptual test where subjects interact with a user-adjustable system and their adjustment preferences and the resulting satisfaction levels are studied.

The details are presented in our paper:

In the paper, we also show the application of the A/ST for the evaluation of a Dialogue Enhancement system, i.e., an object-based audio system which enables the content consumer to control the balance between the dialogue and all other audio sources.
