What is an "earmuff"?

An earmuff is a device that is designed to protect the ears from loud noises in a variety of work settings, including construction sites, airports, and factories. They consist of two ear cups that are connected by a headband and made from a variety of materials such as plastic, foam, and metal. The ear cups are padded with sound-absorbing material, and they come in different sizes to fit various head sizes. They are designed to be worn over the ears and provide protection from both high-frequency and low-frequency sounds. Earmuffs are an essential part of personal protective equipment (PPE) for workers who are exposed to noise levels that exceed the safe limit of 85 decibels.
