The new instrumentation tool AVL-PBN supports the prediction of pass-by noise from powertrain test cell measurements.
The prediction algorithm is based on experimentally measured transfer functions from the powertrain compartment to the pass-by measurement point.
Additionally the new instrumentation tool can be effectively used for the detailed analysis of engine and gearbox noise radiation in the powertrain test cell. Based on a 32 channel data acquisition board the system is intended to be quick and easy to apply during daily work in the acoustic test cell.
The pass-by prediction instrumentation supports:
