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.
