Interactive Vehicle Interior Sound Simulation
Virtual auditory environments (VAE) are becoming more and more important for the development phase of vehicles. Interactive simulation introduces a quite new dimension in comparison to laboratory listening tests. In order to achieve an immersive VAE, all relevant sound components have to be realized in a realistic way and updated in real-time according to the drivers actions. A concept is pres...
متن کاملvehicle interior structure borne noise calculation using finite element method
in this paper the interior noise level of a vehicle due to structural vibration, named structure borne noise, as a part of nvh analysis has been investigated. first structural analysis is performed and vibrational behavior of structure carried out due to power plant excitations. then interior acoustic cavity response for such excitation and resultant noise is determined. vibrational analysis is...
متن کاملModeling road traffic noise using distributions for vehicle sound power level
Research evidence suggests that annoyance, sleep disturbance and other health effects of road traffic noise exposure may be related to the level and number of noise events caused by traffic as well as to energy equivalent measures of exposure. Because measurements show that the variation in noise emission between vehicles within the same category can be considerable, it is essential that the in...
متن کاملPsychoacoustic Evaluation Model on the Luxury of Sound Quality in Vehicle Interior Noise
This paper studied the comprehensive evaluation index of sensory luxury of Sound Quality in Vehicle interior noise. The relationship between it and psychoacoustic parameters under different conditions was studied. Four types of vehicle real-time noises were recorded at several running speeds and later were subjectively evaluated in the testing room by semantic subdivided method. According to th...
متن کاملThe sound quality of vehicle interior noise : a challenge for the NVH - engineers
The sound quality of vehicle interior noise has become a very important task for the acoustic engineers since more than 20 years. As vehicles become more and more quiet, the customer’s sensitiveness for the acoustical comfort increases. On the one hand, no disturbing noises should be heard and on the other hand, the perceived sound quality, for example from the powertrain, should fulfill the ex...
