Lecture 01: Introduction to Sound

Welcome to the first lecture of the NPTEL course on "Noise Control in Mechanical Systems".
This lecture, explores the fundamental phenomenon of sound, mechanisms behind its generation, and introduce the different types of waves, and the wave behind propagation of sound.
This lecture also describes the key sound wave terminologies and their essential mathematical relationships, for fundamental understanding of advanced topics in noise control.
Stay tuned as we uncover more about noise control techniques in upcoming lectures.
