Abstract
Binaural Transfer Path Analysis and Synthesis (BTPA/BTPS) were originally developed for assessing the binaural contributions of individual vehicle noise paths. They are powerful modeling tools, enabling engineers to explore noise transfer mechanisms by distinguishing between excitation source strengths and the transfer behavior of individual elements. The methods used in BTPA and BTPS are now more frequently confronted with limitations which can only be handled by detailed observation of the various influencing variables. A promising method is to describe the mechanical interfaces via four-pole parameters. Using this technique, changes in transfer paths (e.g. exchange of engine mounts) can be simulated by a tool providing immediately-audible results.
