Sound/Acoustics

The Boxster (987) and Boxster S (987) are recognizable by a typical Porsche load related exhaust note both outside and inside the vehicle and has been brought into line with regulatory vehicle noise limitations. Porsche engineers have managed to comply with all worldwide noise regulations. Suppressing wind and tire noises has allowed greater emphasis to be placed on the engine sound. The insulation (for the passenger compartment) has been developed to optimize the typical Porsche interior sound while retaining the interior noise level. The absorbing effect of the components has been improved without fundamentally impairing the insulating effect through the selective use of new insulating materials. One of the goals in adjusting the passenger compartment sound has been to reduce background noise in the higher frequency range and to emphasize more strongly the sporty, load-related exhaust note and intake sound between 300 and 600 Hz.
