Ear plugs (noise reduction pads) Ear-muffs are composed of two noise reduction bowls that cover the bowl of the ear and lie flush with the head with soft sealing cushions, usually filled with plastic foam or liquid. Damping bowl are usually filled with sound absorbing material. Ear-muffs may be worn separately or mounted to safety helmets. Ear plugs (noise reduction pads) - are hearing protectors worn in the external ear canal. They are intended for tight closing of the ear canal. Ear plugs are divided into single-use and multiple use plugs. They may be shaped by a manufacturer (e.g. made of silicone) or by a user (e.g. made of foam). Ear plugs are also available in a headband version, where the headband functions as a pressure spring and is used for maintaining the plug inside or at the entry point to the ear canal. The headband may be worn on the top of the head, under the chin or at the back of the head. The size of the plugs should be carefully selected for every user, since ill-suited plugs may cause a feeling of discomfort or irritation of the ear canal.
