ABSTRACT The present specification discloses an ear plug of soft, resilient, and generally tubular construction that is easily inserted by the worker after only the bares minimum of instruction, the plug being such as to comfortably fit in ear canals of different sizes so that generally only a single size ear plug need be provided for all workers. The body of the plug is of stepped construction so that a good seal between the plug and the ear canal is provided, and the wall thickness is varied to produce a balance of desired resilience and strength. The flared outer end of the plug aids in the insertion and removal of the plug, and the use of a suitable plastic type material permits the plug to be made at a very low cost.
