Abstract
Methods and system for predicting sound pressure and/or sound pressure level caused by a vehicle horn are provided. An acoustic model of the horn is generated through the use of inverse numerical acoustics and boundary element methods. Additionally, an acoustic model of the vehicle is generated using boundary element methods. By combining these acoustic models and using the acoustic model of the horn as input into the acoustic model of the vehicle, sound pressure and/or sound pressure level at points within the acoustic domain encompassing the acoustic models can be predicted using boundary elements methods.
