Wind Noise Testing
Wind noise is an aerodynamic noise related to the body design and turbulence from components such as side view mirrors, wipers, cavities, etc. It is most disturbing at speeds above 100 km/h (approx. 60 miles/h), but is becoming more and more important when powertrain and road noise is being reduced. Careful design minimizes the problem, so early concept studies are important. Wind noise is, however, often an issue which is discovered late in the development process. It requires fast and efficient analysis since measures like extended seal systems or sound packages are expensive.
ACOUSTIC TEST TYPES WITHIN WIND NOISE TESTING
Wind tunnel tests with interior microphones measuring the contribution from a single system or component when all other possible disturbing sound sources are temporarily eliminated with tape, clay or similar.
