A comparison of acoustic sensitivities of the 2000 Ford Taurus and 1999 Toyota Camry identifies an interesting paradox: the Taurus has a competitive advantage over the Camry when comparing body-only transfer functions, but a handicap to the Camry when the subframe is included in the measurements.Further, the Taurus subframe/mount subsystem actually behaves as an amplifier rather than an isolator over most of the powertrain excited frequency range.This report attempts to explain the cause of these behaviors through a hybrid CAE/test method and recommends a design strategy to lower the Subframe to Driver's Right Ear sensitivities of the Taurus.
