Enhancement of low-frequency sound insulation using piezoelectric resonators

Abstract In this paper, piezoelectric patches and electrical circuits are associated to attenuate vibration of a flat panel. The resulting electrical network is equivalent to a resistor–inductor–capacitor circuit performing as a tuned vibration absorber, denoted by piezoelectric resonator. The choice of design parameters, such as the correct placement for piezoelectric patches and the optimal electrical circuit elements, is assisted by finite element simulation and theoretical analysis. Measurements of sound transmission loss and modal analysis are conducted to demonstrate the structural vibration control and its resulting sound insulation performance. It is shown that, despite its reduced mass, the piezoelectric resonator can be more effective than conventional damping in low frequencies, which enables the overall sound insulation system to perform, with lower mass, in a wider frequency range.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
