Allocation and evaluation of engine noise components

The perceived noise quality of internal combustion engines is significantly influenced by the occurrence and characteristics of individual disturbing noise components. Within the scope of an FVV research project, a methodology was developed at the Institute of Internal Combustion Engines of the RWTH Aachen University that enables the extraction of individually audible engine component noises from a total engine noise and the automatic quantification of the annoyance level of these components. In addition, the methodology allows the synthesis of a newly weighted total engine noise from the separated noise components for target value definition. AUTHORS
