Ear defenders, also known as earmuffs or ear protectors, are a type of personal protective equipment designed to protect the wearer's ears from excessive noise. They consist of two ear cups connected by a headband, with each ear cup containing sound-absorbing material and often a cushion for comfort. The ear cups are designed to fit over the ears, creating a seal to block out noise. Ear defenders are commonly used in industries such as construction, manufacturing, and aviation, where workers are exposed to high levels of noise that can cause hearing damage. They are also used by individuals participating in loud recreational activities, such as shooting or attending concerts. Ear defenders are an effective way to reduce noise exposure and protect the ears from potential harm.
