Abstract

This PhD project aims to develop active noise and sound quality control systems for hybrid and electric cars. This new paradigm in powertrains for vehicles, poses new challenges for designing and analyzing noise and vibration. Novel acoustic emissions perceived at the passenger's cavity are due to new devices required by these kind of vehicles, e. g. frequency inverters and range extenders, as well as the specific conditions of the electric and/or internal combustion engine harmonic disturbance. Active control techniques are devised as a solution for these new challenges, intended to transform the perceived acoustic field and thus improving sound quality for the disturb. It is expected that, as a result of the control systems to be proposed during the PhD project, new developments in active control be obtained from the concept of changing the amplitudes and/or the relative phases among harmonic components of the acoustic stimuli. Recent research has demonstrated that by controlling loudness, roughness, tonality and acoustic sensory pleasantness, sound quality of a disturbance can be notably modified. To this end, activities such as design, simulation and implementation of control systems based on active structural acoustic auralization of harmonic disturbances produced by electric/hybrid engines are proposed in order to change their time-frequency structure, in order to reach sound quality targets.
