Lecture 50: of the NPTEL course on "Noise Control in Mechanical Systems", delves into the working principles of sonic crystals, including Bragg's law for wave interference and local resonance. It also discusses limitations related to Bloch's band gap and the role of local resonance in sonic crystals.

Stay tuned as we uncover more about noise control techniques in upcoming lectures.
