Traffic noise pollution has represented a significant challenge for modern societies, requiring the development of innovative noise mitigation strategies. In the last decades, intensive research has been developed into the design and evaluation of noise barriers but there still lacks a ... Read More
Multiphysics acoustics is increasingly used to design products to meet sound, ultrasound and infrasound and other structural, thermal, electromagnetic requirements. In this paper, Multiphysics Acoustical applications such as digital stethoscope, glazing products and acoustical ... Read More
The present work deals with a numerical investigation of resonating systems used for noise control applications. In literature one can find analytical models based on fluiddynamics concepts for evaluating losses occurring across the holes of the perforates. In the paper an acoustical ... Read More
Vibro-acoustics encompasses the study of interaction between sound and vibration. For example, sound transmission analysis is important to design vehicle bodies and building partitions, advanced noise control technologies can ease the increasing noise pollution problem in densely ... Read More
This poster focuses on the development of practical acoustic metamaterials for the reduction of low frequency industrial noise. High noise levels generated by industrial machinery can cause major environmental problems and stakeholders are looking for novel solutions. Particular ... Read More
Bloch waves in infinite periodic structures – much in vogue in the present metamaterial age – can be conveniently studied by COMSOL Multiphysics® software. This is demonstrated by a simple, yet rich two-dimensional example: a perforated sheet with square symmetry. Instead of plane waves ... Read More
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 ... Read More
Active noise control systems have recently been proposed and implemented on domestic window apertures. However, their fundamental limits, and performance in the presence of glass windows has not been studied in detail. The passive acoustic attenuation through an aperture covered with ... Read More
Mufflers are devices used to attenuate engine exhaust noise. Muffler design has become more challenging as the customers look out for good exhaust sound quality, especially for motorcycles. Performance of a muffler in an automotive exhaust system is characterized by Transmission Loss ... Read More
A 2D numerical model for determination of sound reduction index is set up in this work. Results are in good agreement in middle and high frequency range when using solid structure approximation. Results are compared with experiment. Read More
