Figure 2 - Design & Test Process with LEA & ASD (Active Sound Design) ModulesFigure 3 - Example of how target orders are enhanced within ASD Module3. Chrysler experience of <strong>engine</strong> <strong>sound</strong> design3.1 Background/ChallengeThe Interior <strong>sound</strong> signature of the new proposed sporty variant of a production vehicle did notmeet the target image <strong>sound</strong> expected in the sport segment. Chrysler desired a more competitive andsporty <strong>sound</strong> <strong>to</strong> differentiate this product in the marketplace. Since the vehicle architecture wasalready in existence, <strong>sound</strong> <strong>enhancement</strong> solutions were limited <strong>to</strong> re-tuning induction and exhaust.Exhaust tuning options were very limited since the vehicle was already close <strong>to</strong> the legal pass-byrequirements. Designing/fabricating and testing a new exhaust tuning code was beyond the allocatedbudget, and outside the scope for timing. Opportunities explored for induction tuning did not resultin a major <strong>sound</strong> quality improvement.4
