Dr. Lissek's core competences focuses on electroacoustic expertise, namely know-how on loudspeaker and microphone design, acoustic transmission lines lumped element models, as well as the design of arrays of transducers for sound reinforcement and acoustic imaging, especially for communication (line arrays, wave field synthesis) applications or noise metrology (beamforming, near-field holography, goniometry). Together with this specific skill, he and his group claim a broader acoustic expertise such as the characterization and model of complex sound sources, including structure-fluid interactions, sound propagation models within complex 3D fields including weather effects and other fluid and thermodynamic interactions, and auditory issues of sound (namely psychoacoustics, including sound design).
As a combination of these competences, active noise control has become a hot activity of Dr. Lissek in the last decade, leading to the development of practical concepts for active noise cancellation, active impedance control, or the recent shunt loudspeakers techniques used as acoustic absorbers, the core of these developments remaining the electroacoustic transducers. As a consequence of the latter, the acoustic group led by Dr. Lissek is investigating new research areas such as acoustic metamaterials, that should lead to acoustic cloaking capabilities.
