Acoustics
Acoustics. Instructor: Prof. Nachiketa Tiwari, Department of Mechanical Engineering, IIT Kanpur. This course discusses topics in acoustics: acoustics fundamentals, terminology, 1D wave equation in Cartesian coordinates and in spherical coordinates, transmission line equations, electromechanical transduction and mechanoacoustic transduction using lumped parameter approach, modeling of complex electromagneticmechanicalacoustic systems, sound radiation, propagation and attenuation of sound, waveguides, and the interplay between vibrations and acoustics.
