The current context of the automotive sector leads to continuous improvement. For all customers, the quality of our products passes by an acoustic comfort. Therefore, a large part of our production requires an acoustic control. Our role as a supplier is to transcribe these requirements – which are subjective evaluations – in measurable criteria on production lines. Today, to make an acoustic control on our steering gears, a workstation uses accelerometers to measure the noise caused by the mechanical linkages and is able to determine if the product respect the acoustic limits. In case of defect, we want to identify which component from the assembly is responsible of the acoustic defect, so, after a specific treatment and analysis of the signal, we can isolate one component as the root cause.
