Sonic

Source Core Rulebook pg. 636 2.0
An effect with the sonic trait functions only if it makes sound, meaning it has no effect in an area of silence or in a vacuum. This is different from an auditory spell, which is effective only if the target can hear it. A sonic effect might deal sonic damage. A creature with this trait has a magical connection to powerful sound.
