This thesis documents the analysis and design of a Nice Noise System (NNS). The purpose of the NNS is to find a solution to a problem at Sauer-Danfoss, where truck are driving around in a noise environment and are not being heard. This is a safety hazard to the workers that is working along side the truck everyday. The thesis analyse the problem, in terms of the workers, the truck and the environment. The thesis also studies what sound would be appropiate for the truck, by defining principles based on the behaviour of the truck. The design of the NNS is based around a computersystem, digitally storing the sound for the truck. A pitch bending method is chosen to make the truck sound follow the speed of the truck, and to make the impression of a real truck, when in motion. A listening test has been carried out at Sauer-Danfoss, where workers from the production facility has participated. Sound and demos are included on a \cdrom in the back of the report.
