VIBRO-ACOUSTICS: FUNDAMENTALS AND APPLICATIONS Grade 6 such as a spiral wireThe subject of vibro acoustics is important for the design of machine elements and structures, to minimize sound generated by them. For better machine designing, it is necessary for machine designers (mechanical engineers) to have a thorough knowledge of vibro acoustics. Furthermore, since the design cycles of machines have become shorter, designers will have to design quiet machines at the drawing board stage rather than applying band aid techniques
