Every day, millions of people use headphones to listen to music, while watching movies or playing video games, and to communicate with others. Unfortunately, the sounds presented via headphones are usually perceived inside the listener’s head rather than at a realistic external position. This is because binaural sound reproduction via headphones typically lacks head tracking and bypasses the...

In the horizontal plane, lateral precursors shift the perceived location of a subsequent probe sound toward the midline, whereas central precursors push perceived locations further toward the sides. These effects are typically stronger for headphone presentation than for loudspeaker playback in anechoic...

Sound source directivity plays a role in perception, including for scene analysis and speech recognition in complex acoustic environments. For example, speech directivity cues enhance target speech recognition when the target faces the listener and masker talkers face away from the listener. We examined this effect of speech directivity on target speech recognition as a function of masker head...

Noise is a persistent issue in open-plan offices, and soundscape temporal and spectral variations were found to explain part of perceived annoyance. While acoustic treatments and sound masking systems can help reducing the overall level and speech intelligi- bility, they are not designed to adapt to those varia- tions. Other approaches based on a transformation of the existing soundscape have...

For computational room acoustic models, a suitable characterization of boundaries is required.

Climate change led to increased temperatures during summer. Many homes in Europe and India are naturally ventilated. Opening or closing windows is one of the perceived controls to adapt to acoustic and/or thermal environments. When occupants open windows to cool indoor temperatures, they may also be exposed to sounds from outside, which might be unwanted sounds like traffic. Occupants react...
