Simulation of Vehicle Noise in the Virtual City

چکیده
A tool that will both auralize and visualize exterior vehicle noise in real time has potential applications in environmental planning, virtual environments and the computer games industry. This paper describes the simulation of moving vehicle noise for implementation within a complex graphical urban simulation "Metropolis" a development platform specifically aimed at simulating real crowd behavior in central Dublin with full audio and visual immersion of the listener. In this paper methods of vehicle simulation using a combination of sampled (power unit) and synthesized (tyre) sources are investigated. Auralization of vehicle noise is achieved through the inclusion of spatialized audio rendering (realized through FMOD sound systems) and is integrated into the graphical animation. Preliminary multi-modal tests will establish the level of detail required for a good perception of immersion to emerge.

In this paper, the acoustic environment in a vehicle cabin under the influence of highfrequencies aerodynamic sources has been studied. Some panels on the windshield, the roof, the doors, the front pillars, and the floor of a vehicle simulated as input source of noise when the car is moving at high speed, i.e. 112 km/h. The status of vehicle cabin in each of these modes has been studied and com...

Since the electric motor of pure electric vehicle replaced the engine, the "masking effect" disappears, and the problem of vibration and noise of the transmission becomes prominent. This is generated during the gear meshing and is transmitted to the housing through the shaft and bearing. Thereby, radiation noise of the housing are generated. The prediction and analysis...
