Whether it is a competitor’s vehicle or another company model, benchmarking vehicles is a useful method of gathering valuable data for target setting based on customer preferences. And sometimes, especially if it is a competitor’s vehicle, it is not possible or inconvenient to evaluate sounds in a test environment. Perhaps only in situ tests will do, or the vehicle cannot be removed from service (for example with public transportation vehicles).
Brüel & Kjær has developed an NVH tool for quick, non-intrusive recording and analysis called SoNoScout. It can be carried in the tester’s pocket on a train or bus without distracting the passengers or in a competitor’s vehicle where it can be combined with a GPS unit to generate a map of the test route, measure speed and even generate an RPM profile. The software runs on a PDA with microphones binaurally mounted on a headset for quick recording.Products:
