摘要：
An earmuff hearing protective device whose earmuffs each include a generally cup-shaped, substantially rigid shell having a head-facing rim； a head-engaging, ear-encircling cushion affixed to the rim； and a sound absorber inside the shell. The sound absorber has a moisture-resistant integral skin substantially surrounding an open cell foam interior having lower density and greater porosity than that of the skin. The skin helps discourage moisture pickup and microbial growth.
