Pass-by-Noise Testing

m+p international's SO Analyzer based system is the very latest fully integrated solution for  Pass-by-Noise (Drive-by-Noise) testing. It is an advanced add-on module within the standard SO Analyzer suite of products. Utilising specially developed GPS technology for both position and speed information significantly reduces the equipment required and provides a simple and easy-to-use system that is operated entirely from within the car and by just one person.
