According to the Oxford dictionary the word cacophony means: "A harsh discordant mixture of sounds."
According to Wikipedia the word cacophony means "harsh, often discordant sounds that are often meaningless and jumbled together."
The root caco- means "bad, ill, poor", from Latinized form of Greek kako-, from kakos "bad, evil," considered by etymologists probably to be connected with PIE *kakka- "to defecate".
