Event: 2nd International Conference on Vehicle Comfort Ergonomic, Vibrational, Noise and Thermal Aspects
The paper presents the results of a preliminary study for the implementation of an active noise control (ANC) on a car ventilation system. Here are also discussed some important questions regarding the electronic treatment of the broadband random noise coming from such a car ventilation system, also including those related to the correlation and coherence existing among the various random noises generated and released by the system. Concluding, some experimental results regarding this particular kind of realization are presented.
