Listening experiments
Welcome to our listening experiments, where the world of sound comes to life!
In carefully designed experiments, we delve into the many facets of auditory and cognitive perception, as well as technical acoustics. In various scenarios, participants are placed in virtual (acoustic) environments in which the boundaries of reality are blurred, offering a unique perspective on auditory phenomena.
A cornerstone of our listening experiments is binaural synthesis, a technique that reconstructs spatial (3D) audio signals via headphones to immerse participants in an impressive virtual auditory world. This method allows us to gain valuable insights into the way we process and localize acoustic stimuli.
We are always looking for curious individuals who want to help us advance acoustic research. Whether you have a keen interest in acoustics in general or want to gain new experiences, we invite you to join us on this journey. Sign up for one of our current listening experiments or be informed directly via our email distribution list about new, exciting listening experiments.

Source width of virtual sounds
Almost all sound sources around us have a certain extent or emit sounds at different positions. In this listening experiment, we will test how important this “source width” is for the presentation of virtual sound sources.
