Experimental and Theoretical Investigation of Acoustic Metamaterial with Negative Bulk-Modulus
Acoustic metamaterials are structured materials of negative mass density or negative bulk-modulus or both of them. Materials are tailored in sub-wavelength dimensions so as to get these negative properties. This paper compares the result of an experimental investigation of acoustic ... Mehr lesen
A MEMS Condenser Microphone for Consumer Applications
The MEMS microphone is also called microphone chip or silicon microphone. The pressure sensitive diaphragm is etched directly into a silicon chip by MEMS techniques and is usually accompanied with integrated preamplifier. Most MEMS microphones are variants of the condenser microphone ... Mehr lesen

Characterization of a Tonpilz Transducer and Performance Analysis for a MEMS-Transducer Array
In this paper, we develop and analyze a standard piezoacoustic Tonpilz-transducer model for underwater acoustics in Comsol by addressing the attendant piezoelectric and pressure acoustic multiphysics phenomena. Transducer properties that are studied and characterized are the center ... Mehr lesen
Development of Mathematical Model for Determining Sound Reduction Index of Building Elements
Although we know the physics inside a media where the sound waves propagate, determination of material\'s or structure\'s sound reduction index is not an easy task. The lack of good engineering solutions proves the point. The only reliable way to calculate the sound reduction index is ... Mehr lesen
Computational Acoustic Attenuation Performance of Helicoidal Resonators
This paper concerns the problem of obtaining proper acoustic attenuation performance through computations. COMSOL was used to solve acoustics systems with helicoidal resonators in the frequency domain. Based on the studies of insertion and transmission loss of helicoidal resonators, a ... Mehr lesen
Electro-acoustic Coupling in Nematic Liquid Crystals
Liquid crystals - as all liquids - are generally modelled as incompressible media. In fact, mass-density changes occurring in these mesophases are minuscule and inconsequential in most regimes of interest. However, liquid crystals exhibit also phenomena that call for a more refined ... Mehr lesen
