Acoustic waveguide - Wikipedia
An acoustic waveguide is a physical structure for guiding sound waves, i.e., a waveguide used in acoustics. Examples. One example is a speaking tube used aboard ships for communication between decks. Other examples include the rear passage in a transmission-line loudspeaker enclosure, the ear canal, and a stethoscope.
