Journal of Vibration and Sound (JVS) is an Open Accesses biannual publication sponsored by the Iranian Society of Acoustic and Vibration.  JVS publishes articles in Persian Language, and in two issues per calender year. The Journal is the venue for publication of original research concerning mechanical vibration and acoustic. Our mission is to serve researchers and practitioners who seek cutting-edge theories and computational and experimental methods that advance these fields. Our published studies reveal how mechanical vibration and acoustic impact the design and performance of engineered devices and structures and how to control their negative influences.
