Increased distribution efficiency with more quiet delivery vehicles

The goal of the project is to develop scenarios and to define requirements for road transport vehicles so they can be used for distribution of goods at nighttimes in urban areas in Sweden. Applied Acoustics investigates the requirements on noise emission during evenings and nights that can be demanded for transportation vehicle from the perspective of the society. The method is to develop a computer model for virtually simulating sound in apartments from single vehicles passing by in the street – an auralisation model. The model is used to study different cases, especially by listening tests to investigate annoyance and restoration of humans when a vehicle is passing by. The project will also develop a modified vehicle with lower noise emissions for validation of the conclusions. The whole noise path from the sources of the vehicle in the street, through the city block and building, to a human in an apartment is considered. Thus, the work includes vehicle acoustics, community noise and building acoustics, and human response and reaction to sound.
