CEVAS - Silent air ventilation equipment design
Overview
Background & policy context:
The sound quality problem inside the car cabin is important in the automotive field, especially in the case of upmarket vehicles. The reductions of the noise produced by internal combustion engines and the emergence of hybrid and electric solutions have transformed the perception of sound by the user. The acoustic contribution of equipment such as the HVAC has become paramount and must be studied from the design stage.
Objectives:
The main purpose of Cevas project is the development of a virtual and acoustic prototyping computer tool on the air conditioners and cooling batteries for electric and hybrid vehicles. The tool should allow to predict the noise generated by ventilation systems and design solutions at less cost and with less delay to reduce noise and improve sound quality of these embedded systems.
The project results will be integrated into a calculation software that will interface with an "acoustic synthesis module" allowing to quantify through listening the influence of each component of the internal circuit on the overall acoustic performance and on the sound quality of the ventilation system.
The integrated tool should allow the assessment following psychoacoustic sound quality ventilation systems criteria for different conditions of use and if vehicle integration.
