Virtual Binaural Auralisation of Product Sound Quality
نویسنده
چکیده
The ‘Binaural Transfer Path Analysis and Synthesis (BTPA and BTPS)’ techniques have been developed for the prediction of sound quality in vehicles not only in terms of numbers and graphs, but also for binaural auralisation. The methodology, based on a combination of test rig measurements and acoustic simulation, has been used successfully by HEAD acoustics in the last several years within numerous consulting projects and it has proven its suitability for efficient sound design engineering and troubleshooting of vehicle noise. BTPA and BTPS enable a prediction of vehicle interior as well as exterior noise and sound quality based on any number of modifications to the transfer paths of the baseline vehicle. As a result, test rig measurements of various components can be used to assess the sound quality impacts of component exchange.

MATERIALS REFERENCE ISSUE Ability to both feel and hear the results of engineering decisions via a “virtual car” – simultaneous engineering – can significantly shorten vehicle development time. Sound quality and discrete vibration at the driver’s position may be predicted and ‘driven’ before the first prototype is built. Although sound quality cannot yet be predicted in an unknown chassis, the ...
