LEAM - Laboratori d'Enginyeria Acústica i Mecànica
El LEAM té com a missió la recerca en el control del soroll i les vibracions i traslladar el coneixement adquirit a l'entorn socioeconòmic. La recerca abasta des de la formulació de models analítics i numèrics fins a la validació experimental en plantes pilot i en situacions reals. Els principals camps de treball són la modelització de l'impacte vibratori d'infraestructures, el control actiu de soroll, l'acústica ambiental i la detecció de fallades per emissió acústica.
