muffler

Definition

A device attached to the exhaust system of an engine that reduces noise by baffling and absorbing sound waves. Also a common term for a scarf or wrap worn around the neck for warmth or fashion.

Example Usage

The old pickup truck needed a new muffler because it was so loud the neighbors complained.

Origin

From the verb 'muffle,' meaning to wrap or deaden sound, first used for automotive exhaust systems in the early 1900s.

Fun Fact

Early mufflers were simple perforated metal tubes; modern ones use complex baffle systems and sound-absorbing materials to meet strict emissions noise standards.
