There are applications where it would be beneficial to use structural transducers for acoustic/noise sensing. Such systems may include systems where the sound source is a radiating structure, such as in vehicle cabins. For instance, structural transducers can be attached to the structure inside a vehicle cabin and a virtual sensing strategy can be used to predict the acoustic properties within the cabin. This virtual sensing strategy can then be combined with an active vibration/noise control method for reducing the noise level inside the cabin. A virtual sensing and control method will be developed for the purpose of creating multiple zones of quiet for systems where the noise is radiated from a complex radiating structure, allowing the method to be used for practical applications.
