Research Acoustics

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.

1 Motivation

When purchasing a passenger car, the customer’s choice is increasingly influenced not only by objective criteria but also by the quality-based impression of the vehicle. The perceived noise quality of the powertrain plays a central role in the purchase process. The occurrence and the characteristics of individual disturbing noises...



This report is the scientific result of a research task carried out by the Research Association for Internal Combustion Engines (Forschungsvereinigung Verbrennungskraftmaschinen e. V., FVV) under number 1207 and worked on at the Chair of Internal Combustion Engines at RWTH Aachen University under the direction of Prof. Dr.-Ing. Stefan Pischinger. The work was carried out by the Federal Ministry of Economic Affairs and Energy (BMWi) through the Federation of Industrial Research Associations e.?V. (AiF no. 18834 N/1). The FVV thanks Prof. Pischinger and the scientific editor, Christian Schumann, M. Sc. for the implementation of the project as well as the BMWi and the AiF for the financial support. The project was accompanied by a working group of the FVV under the leadership of Dr. Michael Fischer, Robert Bosch GmbH. This working group expresses its gratitude to the FVV for the great support.
