Fields of expertise
Active noise control.
Head of the Acoustic Group at the Laboratoire de Traitement des Signaux LTS2.
Specialty: Development of ElectroAcoustic MetaMaterials. Bridging the gap between active loudspeakers, electroacoustic resonators, and acoustic metamaterials.
National Focal Point (NFP) for Switzerland within the X-Noise EV European Network (FP7-Aircraft External Noise Research Network and Coordination).
Teaching activities: electroacoustics (Bachelor), Audio engineering (Master), active noise control (Doctoral program).
After a PhD in Acoustics (Les Matériaux Actifs à Propriétés Acoustiques Variables, Université du Maine, Le Mans), Dr. Lissek joined the Laboratoire dElectromagnétisme et dAcoustique to supervise the active noise control activities of the Acoustic Research Group, headed by Prof. Mario Rossi.
Since 2006, Dr. Lissek took the leadership of the Acoustic Group, and launched several expertise activities together with new research topics at EPFL, especially in the frame of Aircraft Noise Research in EU projects (FP5-Silence(R), FP6-X3 Noise, FP7-TEENI, OPENAIR, XNOISE EV). He is also appointed expert by the EC to evaluate research proposals in calls for projects in Aeronautics within FP7.
Since 2015, Hervé Lissek and the Acoustic Group are affiliated to the Laboratoire de Traitement des Signaux LTS2
Dr. Lissek is now heading a team of 6 people, among which 4 PhD students, 1 Post-doc, and 1 Engineer.
Dr. Lissek's core competences are related to electroacoustics, namely know-how on loudspeaker and microphone design, acoustic transmission lines description via 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.
