Project Details
Initial situation:
The EU's increasingly stricter legislation regarding noise level limits for the type approval of passenger cars is placing ever higher demands on vehicle acoustics. One of the biggest influencing factors is the engine, which is able to significantly influence vehicle acoustics thanks to the exhaust system equipped with the ANC system.
Project assignment:
The order from an exhaust system supplier to EVOMOTIV included the integration of a suitable sound pressure sensor and its mechanical connection to the ANC system.
Implementation:
A sensor that is already available on the market was integrated into the ANC system, taking into account the special acoustic requirements. The mechanical connection of the sensor to the exhaust system played an important role. The requirements regarding vehicle acoustics and environmental requirements according to LV124 were ensured through appropriate acoustic measurements using PAK or Klippel DB-LAB as well as tests on the test bench and on the vehicle.
Solution:
The test results and corresponding measurements were documented in the customer-specific form and prepared for subsequent vehicle-specific applications.
