- Acoustic_transmission_line abstract "An acoustic transmission line is the acoustic analog of the electrical transmission line, typically thought of as a rigid-walled tube that is long and thin relative to the wavelength of sound present in it. The term "acoustic transmission line" is synonymous with "acoustic waveguide" Waveguide(acoustics). The now mostly obsolete speaking tube served to transmit sounds to a remote location with minimal loss and distortion, as a simple coaxial cable or waveguide does for electrical signals. Musical wind instruments such as pipe organs, woodwinds and brass instruments can be also be modeled in part as transmission lines, though their job also includes generating the sound, controlling its spectrum, and coupling it efficiently to the open air, functions analogous to those of electronic oscillators, filters and antennas.The comparison between an acoustic duct and an electrical transmission line is useful in "lumped-element" modeling of acoustical systems, in which acoustic elements like volumes, tubes, pistons, and screens can be modeled as single elements in a circuit. With the substitution of pressure for voltage, and volume particle velocity for current, the equations are essentially the same. Electrical transmission lines can be used to describe acoustic tubes and ducts, provided the frequency of the waves in the tube is below the critical frequency, such that they are purely planar. The rest of this article will describe a particular use of the term, "acoustic transmission line" as the name of a specific audio speaker enclosure topology, in which sound from the back of the bass speaker chassis passes along a long (generally convoluted) path within the speaker enclosure. The energy is absorbed on this path, or emerges from the open end in phase with the sound radiated from the front of the driver, enhancing the output level at low frequencies.".
