Abstract
Background and Aims: Noise exposure can lead to several complications such as tinnitus, hypertension, sleep problems and hearing loss. Considering the prevalent entrance of nanotechnology in different fields of science, this study aimedto review the use of sound-absorbing panels _composed ofnanoparticles_named nanocomposites panels.
Materials and Method: In this reviewal study,search engines like Magiran, Sid, Medlib, Iran Medex, Google Scholar, ISI web of knowledge, Scopus and Pubmed.com were used. Searched key wordswere: Sound absorption, acoustic panel, acoustic barrier,sound absorbent and sound absorbing panels. A total number of 51 articles based on the aims of the study were selected and the related information was extracted.
Results: One of the best and the most efficientmonitoring methods for noisy sources is applying thesound absorbents. These sound absorbentsplay important role in controling the room noise, industrial noise, studio sounds, automobiles and other kinds of noise pollution. Soundabsorbent materials arenormally used to fight back against the hostile effects of reflected sounds from the solid surfaces and they alsocausedthe reduction in the sound level of the reflected sounds.Considering the large area of application of theNano-materialsin acoustics economy,in comparison with porous material and other materials, theSoundabsorbent materials have got a various levels in terms of sound absorption.
Conclusion: The application of sound absorbents,which are made based on polymer materials and nanoparticles,canpreventfrom many occupational diseases and because of the economicalproduction costs of these materials,can play an important role in the national economy
