Occlusion plugs designed for temporary insertion and occlusion of the external ear canal. These plugs are typically soft cylindrical devices made of soft rubber, rubber-like materials (e.g., soft silicone), or wax. They are mainly intended to protect the wearer\'s ears from loud noises or the intrusion of water, foreign bodies, dust, or excessive wind. Ear occlusion plugs are available for many particular needs (e.g., sleeping, travelling, shooting, and/or studying). Special-use ear plugs that include filters that seal out water but allow sounds to pass through for swimming, damping-air pressure changes (e.g., in airplane cabins), or attenuate high-frequency sounds while allowing normal conversation are also available. Some occlusion ear plugs are attached to headbands to facilitate their use.
