We are mainly consultants, but we also have developped some products:

+++ NEW +++ Electric Vehicle Interactive Sound Signature System ELVIS3  +++ NEW +++

ELVIS3 is a highly innovative development environment for brand-specific sounds in electric and hybrid vehicles. The system produced by Product Sound generates sounds completely latency free and synthesizes its output depending on the vehicle’s current condition like speed or load. Due to its open architecture it is possible to efficiently develop an extremely broad palette of dynamic sound signatures, ranging from
natural combustion engines to smooth elegant synthetic sounds.

During setup the sounds generated by the vehicle – motors, tires, wind noises – are integrated into ELVIS3 with a few clicks. Thus, sound signature development takes place in a realistic context under real-world conditions. The powerful ELVIS3 realtime audio engine together with the realistic user interface controls allow for a highly effective targeted workflow during the sound design stage. Lengthy calibration and tuning processes without any sonic feedback are now a thing of the past.

Waterproof speakers hidden behind the motor grill warn pedestrians and the visually impaired when electric vehicles are approaching. Laws requiring outdoor sounds for electric vehicles can be fulfilled with minimum effort. Thanks to its flexible architecture, ELVIS3 can output the vehicle’s signature in any speaker configuration, even in surround! By means of its high-quality sound signature your electric vehicle communicates its emotional identity in a clear and concise way.

Metric for the assessment of Seat Belt Reminder Signals

Euro-NCAP donates 3 of 35 points in the crash test evaluation for the Seat Belt Reminder signals. The evaluation of the signals is performed subjectively by the Euro-NCAP inspectors - they rate if the signal is “loud and clearly audible” in a defined situation.
We have developed a metric which performs an automatic and instrumental quantification of the signal. This metric is implemented in the software tool SAM, which does not only render that final evaluation but also useful tips for the optimization of the signal. .

VibroAuditioner - making structure borne sound audible

In contrast to airborne sound structure borne sound is not directly audible. Especially in sound origin analysis or quality control in the production line listening to structure borne sond can be necessary. The VibroAuditioner allows to reproduce structure borne sound via loudspeaker or headphones, an equalizer allows to eliminate distortions and to concentrate on the interesting frequencies.

Customer-specific instrumental evaluation of Sound Quality

The measurement and evaluation of Sound Quality in principle requires a rating of sounds by a customer-respresentative jury. Under specific circumstances an instrumental method to predict the rating can be developed once a comprehensive jury testing has been performed. This method can then be implemented on a PC and avoids further time and cost intensive jury testing. We have e.g. developed such a method for Gear Rattle in interior vehicle sound, for Diesel Impulsiveness, Tonal Components, and Seat Belt Reminder Signals. For more information send an email.
