Ring Of Anti-Silence
Ring(s) of Anti-Silence cancel the effect of any low level “silence” type spells in their immediate vicinity up to a 30 foot radius so long as they are being worn. These have been produced as a yearly class project at the magic academy in Mythburg for quite some time all because too many low level spell casters have tried to cast “Silence” to thwart wizards in the past.
Also if you're one of the players of the campaign reading this, these exist because you shouldn't ever tell the Dungeon Master that you intend to be obnoxious with the “Silence” spell in advance.
For descriptive purposes a Ring of Anti-Silence has a brass band and what might be interpreted as engraved runes running around the outer rim that all look like middle fingers.
