Research in acoustics

Research topics

The research in acoustics is oriented towards the following axes:

Advanced electroacoustics:

• Electroacoustic sound absorption (FP7-OPENAIR, FP7-ENOVAL, CTI-INTERACTS, H2020-ARTEM, H2020-SALUTE)
• Acoustic metamaterials (SNF-METACOU, FP7-ENOVAL, H2020-SALUTE)
• Innovative loudspeakers (H2020-ARTEM, INNOSUISSE-PANACHE)

Signal processing for acoustics

• Machine learning-based noise source classification (Innosuisse-NORA)
• Compressive sensing for acoustics and audio (SNF-CS)
• Microphone arrays signal processing (AAL-iCityForAll)
• Source localization and spatialization (CTI-BHA(L&S), CTI-EXTEND, Innosuisse-ACCESS, Innosuisse-SPHERE)
• 3D audio (Eureka-i3DMusic)

Facilities

The acoustic facilities are the following:

• anechoic chamber
• reverberant chamber
• listening test chamber
