Acoustic Black Holes for Silent SYstemS

The ABHSSYS project ambitions to disrupt noise reduction technologies while addressing the need for industrial decarbonization through a ground-breaking approach: Acoustic Black Holes (ABH). Unlike conventional noise reduction solutions, which often increase mass and carbon footprint, ABH offer significant noise reduction without adding weight. Across EU, 40% of the population is exposed to noise levels exceeding 55 dB(A), leading to health and social costs reaching 40 B€. Reducing noise pollution is therefore a central issue for the EU citizens well-being, and is associated with strong technological challenges in the field of vibroacoustics, particularly in the mechanical industry, one of the main source of noise pollution. ABH is a radically new technology and has strong scientific and industrial potentials, as it is intrinsically i) parsimonious and environmentally friendly: its use reduces the mass and volume of acoustic treatments by around 20%; ii) tunable: ABH enable considerable noise and vibration reduction with only minor or local modifications of the structuring, and are compatible with usual industrial processes; iii) multifunctional: ABH can be applied to many industrial fields without requiring new designs. Moreover, on top of all that, ABHSSYS is a green transition catalyst in terms of noise and vibration reduction. ABHSSYS's ambition is to train a new generation of 11 expert researchers in the field of vibro-acoustic engineering through an innovative interdisciplinary training programme. The consortium of ABHSSYS includes 7 academics, all specialists of ABH, building an exceptionnal team and 6 companies representing a wide range of fields of activity concerned with noise reduction under environmental constraint: Aeronautics (AIRBUS, BOMBARDIER), Aerospace industry (ORUP MORSBOL I/S), Pump industry (GRUNFOS), Acoustic services (SIEMENS), Innovative materials design (METACOUSTIC).
