+ LVA – Vibrations, Acoustics

A research unit of the INSA de Lyon, LVA develops original expertise and methods in the study of vibroacoustic radiation (from source to sound), to identify and localize sources (acting before the transmission of the sound), in the study of sound perception and vibration diagnostics (vibration and acoustic analysis for monitoring and diagnosing rotating machines and for detecting, locating and characterizing faults).
