ESCO Earplugs / Ear Muffs
Earplugs and ear defenders are devices used to shut out loud noises to protect the ears. Earplugs are placed inside the ear. They fit the ear canal closely to shut out the noise. Earplugs are made of materials such as silicone rubber and plastic. Some can be washed and reused, while others are disposable. Various designs and features are available, such as models with strings, and models that can be inserted or removed with gloves. Selecting a type that will be convenient at the user's worksite is important. Ear defenders shut out noise by covering each ear entirely. They have a characteristically headphone-like shape. Some ear defender models can be folded for compact storage. Each model is effective up to a different decibel level, so users should select the right model for the usage environment.
