Description: sound of madness is Gone Gone Gones evolution, this of course occurs when the stand user undergoes a vampiric transformation.

Ability: sound of madness has an ability that allows the user to create sound waves, by pressing the first key, the stand creates a large wave of sound that is so high-pitched that it can shatter bones and destroy buildings. By pressing the middle key, the stand creates a wave of sound that drives the target so insane that they actually experience total brain death which essentially kills the Target and makes them just a dead husk. By pressing the last key, the stand creates a wave of sound that is so low pitched that it has the ability to repair bones completely and fix whatever it hits, this will however not work if the bones are completely separated, like your arm being ripped off or if the object you're trying to repair is completely torn in half.
