The different types of acoustic waves include longitudinal, transverse, surface and guided waves. Longitudinal waves are compressional waves that travel in a direction parallel to the direction of propagation. Transverse waves are shear waves that move perpendicularly to the direction of propagation. Surface waves are waves that propagate along the interface between two media. Guided waves are waves that are confined within an enclosed medium such as a waveguide or pipe.
