Electroacoustic Analogies

This lecture introduces electroacoustic analogies, focusing on the transduction between electric circuits and electro-mechanical systems. It covers the concepts of mechanical-acoustic coupling, inverse and direct analogies, and the methodology for drawing schemes. The lecture also delves into the representation of acoustic systems, small acoustical components, and the principles of acoustic losses. The analogies between electrical and acoustic domains are explored, emphasizing the relationships between flow velocity, pressure, mass, compliance, resistance, impedance, and admittance. The lecture concludes with discussions on acoustic resistances, lumped elements assumptions, and boundary conditions in acoustic waveguides.
