Introduction: Exposure to noise pollution in the workplace is one of the most common occupational hazards and causes hearing loss. One of the ways to control voice in the control industry is by audio absorbers. Nanoparticles can be used to composite materials. The purpose of this study was to design and construct acoustic panels based on gypsum, silicon oxide nanoparticles, hydrolyzed cotton an...
A membrane absorber with single magnetic negative stiffness cell usually can achieve a thin layer sound absorption for one absorption peak at low-frequency. In this paper a sound absorber with multiple magnetic negative stiffness cells was designed to realize a compact design for low frequency sound absorption. This absorber comprises three cells or more in which exists different magnetic negat...
A method for estimating the sound absorption coefficient of a material under a synthesized Diffuse Acoustic Field was recently proposed, as an alternative to classical sound absorption measurements in reverberant rooms. Using sound field reproduction approaches and a synthetic array of acoustic monopoles facing the material, estimation of the sound absorption coefficient under a reproduced Diff...
