>>56388429>personally dunno if you could justify sound being SE against water, fairy, or steel, though)1. Water: Sound travels faster through water and can majorly fuck up fish. Sonar frequently slaughters loads of marine life.
2. Steel: Sound propagates faster through metals even though they are denser than gasses because they are stiffer (more compressible). For example: steel is 6,000 times denser than air but 2,000,000 times more elastic than air, so sound travel 16 times faster in steel then in air.
3. Fairy: Church bells were said to keep away fairies in mythology.
4. Ghost: Exorcisms and other chants to drive out ghosts/evil spirits
