“Soniferous” — from the Latin “sonus,” meaning “sound,” and “-ferous,” a combining form that means “to produce” — is an elevated synonym for “noisy” or “loud.” It’s a more formal adjective, so you might not use it in casual conversation, but you could describe tolling church bells as soniferous. The word could also be used in a joking context, calling out an obnoxious sound as overly loud.
