A visual representation of transmitted sound. This can be portrayed a couple of ways:

• Ring-like waves emanating from a person or audio source (post #2200295, post #2115595)
• A line that fluctuates in tune to a produced sound (post #3817448)

Not to be confused with the Transformers character Soundwave, or the cardiogram which represents a heartbeat.

For water waves, use waves.
