Current Research
Prediction of vehicle pass-by noise
The aim of the project is to develop a predictive model for the current ISO 362 vehicle pass-by noise test. This will involve predicting the overall pass-by noise level from the combined contribution of the major noise sources on a vehicle as it undergoes the pass-by noise test.
Specifically the following noise sources and transfer paths will need to be modelled: intake, exhaust, powertrain and tyres. The quality of the noise source modelling will be paramount in the successful development of the model. For this project a hybrid model will be constructed where it is envisaged that the final data set will be a mixture of experimentally measured data, theoretical predictions and numerical output.
