A design method of polymer polyvinylidene fluoride (PVDF) sensors in an active structural acoustic control (ASAC) system was developed. Genetic algorithms were introduced to search the configuration of PVDF error sensors which observed the vibration components with sound radiation efficiency. Structural coupling analysis showed the high radiation efficiency of the low frequency structural modes. The optimally designed error sensors demonstrated significant improvement of the performance on sound attenuation when compared with non-optimal sensors.
