ABSTRACT:
An ear noise protector apparatus is described, which provides a high level of noise protection, can be worn comfortably, and is economical to use. The apparatus includes a resilient head band with ear protector holders at either end, and a pair of ear protectors that are detachably mounted to the holders. Each ear protector includes a cap of slow recovery resilient deformable material, with a tapered central projection that can be received in the end of an ear canal, and an outer dish-shaped portion that can fit against the ear walls that surround the opening to the ear canal. The head band supplies sufficient force to maintain the cap in a deformed state wherein it conforms to the ear portion that surrounds the ear canal, to form a good seal therewith after being pressed firmly in place.
