Hybrid Isolation of Structure - Borne Sound

vehicle interior structure borne noise calculation using finite element method

in this paper the interior noise level of a vehicle due to structural vibration, named structure borne noise, as a part of nvh analysis has been investigated. first structural analysis is performed and vibrational behavior of structure carried out due to power plant excitations. then interior acoustic cavity response for such excitation and resultant noise is determined. vibrational analysis is...

Structure-Borne Sound and Aurally Active Spaces

ABSTRACT This paper provides a report of a research effort to transform architectural and scenographic surfaces into sound sources and use them in artistic creation. Structure-borne sound drivers are employed to induce sound into the solid surfaces, making them vibrate and emit sound. The sound waves can be perceived both via the aural (airborne diffusion) as well as the tactile (structure-born...

Structure-borne Sound – Phenomena and Prediction

The prediction of the sound radiated by vibrating structures and the layout of measures to reduce it, is a key issue for maintaining appropriate comfort in residential buildings, for guaranteeing the operability of sensitive machinery in production and testing and for the provision of appropriate conditions at working places. For the prediction the excitation, the transmission and the radiation...

FE based measures for structure borne sound radiation

The sound emission of thin-walled radiating components is a common objective of structural optimisation. Acoustic measures are not implemented in common FE-codes. Thus, different velocitiy based measures will be compared: the kinetic energy, the equivalent radiated power (ERP) and the lumped parameter model (LPM). The most common approach the ERP is based on the sound intensity in normal direct...
