Summary:

In modern vehicle acoustics, Active Sound Design (ASD) is a popular method to enhance the interior sound perception of a vehicle. In vehicles with a traditional internal combustion engine, the load dependency of the sound can be increased to give better dynamic feedback. Annoying small-band resonances can be attenuated by boosting the surrounding frequency content, and downsized-engines can be made to sound like the larger ones from former days. However, once a characteristic sound is designed for a specific vehicle, it is a tedious process to transfer this lead-sound to derivatives with a deviating equipment (e.g. same model but different exhaust or audio system). So far, sound designers must adapt the ASD-dataset manually usually this takes several loops of measuring the car's interior sound on a track and adjusting the ASD-settings back in the office. This paper introduces a new method of a semi-automated transfer of the interior sound from a sender to a receiver vehicle by using ASD where the sender and every receiver vehicle must be measured only once. The novel software program automatically compares the measurements of a sender-receiver-pair in terms of an order analysis. The resulting differences are directly used to create a new ASD-dataset for the receiver vehicle. Test results will be presented that show both a remarkable match between the interior sounds of the chosen sender-receiver-pair. Also, the possible reduced effort and time gains will be quantified
