This paper uses analytical methods, including mode-matching techniques and Fourier transforms, to model sound sources in waveguides, particularly in scenarios with structural variations and sound-absorbent materials. The effectiveness of these methods in solving the governing boundary value problem is demonstrated, particularly focusing on understanding sound power output from monopole sources in pipes or ducts. Through numerical experiments, the study explores how factors like structural dimensions, material properties, and source characteristics influence sound attenuation within waveguide structures, highlighting their crucial role in shaping acoustic attenuation properties.
