Invented at the end of the XIXth century, the electrodynamic loudspeaker has not much changed since then. Although the materials have greatly evolved, the geometry and the transduction principle have remained the same. However, in many applications, the bulkiness of the driver behind the ...

When it comes to room acoustic design, it is of paramount importance to be able to assess the sound field distribution inside a room, in order to identify and optimally locate the corrective measures. Generally, an accurate depiction of the sound field would result in an impractically ... Per saperne di più
Noise reduction at low frequencies is a major issue in many workspaces and indoor public places. Unlike mid- and high-frequency noise, low frequency noise is less attenuated by using conventional sound absorbing materials. This communication proposes an electro-mechano-acoustic absorber ...

Quiet zones and other sound zones have been a strong topic of research for some time, due to the interest of creating separate sound environments in a same room, in a large open-space office for example. A number of solutions have been proposed over the last years. This paper further ... Per saperne di più
The main mechanisms of acoustic attenuation in a bundle of fibres typical of lightweight fibrous porous materials are the dynamic viscous drag forces on the surface of the fibres, and the thermal heat transfer between the solid fibres and the surrounding fluid. Microstructure models ... Per saperne di più
Finite element analysis (FEA) can be used to study the electrical properties of conductive ITO thin films. Previous studies have been done on insulating thin films deposited on conductive substrates [1,2]. It was found that changes of electrode size and film thicknesses can cause huge ...

In this work, the production intent design of a motor with controller inside a car seat for head restraint function is analyzed and optimized using the COMSOL Multiphysics® software and the Application Builder. Parameter based multiscale FEA models were developed by using external CAD ... Per saperne di più
Column Loudspeakers employ multiple drivers to get close to a radiating line source. A line source gives several acoustic advantages versus a point source, especially in highly reverberant environments. This property particularly has made column loudspeakers the preferred solution in ... Per saperne di più
The objective of the research is to design a broadband energy harvester device through the two-piece non-linear trapezoidal geometry approach. The performance of two piezoelectric PZT-PZN polycrystalline ceramic composition samples are simulated in the COMSOL Multiphysics® software, and ... Per saperne di più
