>>36895875>>36896288>>36897091>>36898350>>36895900A pokemon's type describes three things in order of importance:
1. Its constitution. Electrics are electrically charged, informing
2. its vulnerability. Electrics suffer grounding, which threatens
3. its innate competence to use electrical powers or resist, by its charge, electric, flying, or steel moves.
Let's apply with sound type:
Sound types are very sensitive to sound, informing a vulnerability to the interruptions of ground, bug, psychic, and, sound moves, which deafen the pokemon that depends on its ears to accurately use noise in combat offensively, or defensively, against, e.g, fighting/dark/and ground Pokemon
The gestalt hereof these qualities seems common with every other type: "sound" is a vital force that opposed weakens a sound pokemon in every way; this is shown by a loss of HP
Opposing arguments
-Sound, noise, sonic, music, etc all sound like the qualities of moves but do not describe the user like Dark or Rock
-Sound sounds like ground and in fact is quite similar to ground, which involves vibrations
-Normal type needs special moves and those are pretty much exclusively sound-based
