abstract = "Personal audio systems in the car cabin are used to divide the listening space into several isolated sound zones. However, the system performance is usually deteriorated due to the complex acoustic propagation characteristics. In attempt to reduce this effect, linearly constrained minimum
variance approach using the measured transfer functions with spectral smoothing is proposed. Real-time experiments with loudspeaker array composed of 24 loudspeaker units are conducted in a real car cabin, and it is demonstrated that the performance of contrast could be improved at the whole
frequency range [200, 1500] Hz, on condition that the measured transfer functions are pre-processed by amplitude smoothing.",
