Sound Waves in Waveguides

This lecture covers the propagation of sound waves in waveguides, discussing topics such as reflection coefficient, wall impedance, standing waves, and sound sources in ducts with rigid terminations. It also explores the modal representation of sound pressure in rooms, room modes calculation, and the modal decay time. The instructor explains the solutions of the wave equation in waveguides, the distribution of sound fields, and the modal representation of sound pressure in rooms. The lecture concludes with a discussion on the detrimental effects of room modes on sound reproduction and the potential solutions to address these issues.
