摘要:
A headband, cap, hat, or the like worn by a child, particularly an infant, includes an embedded sound-attenuation system to protect hearing against loud sounds that might startle, awaken, or injure a wearer. Shells formed of a comparatively soft and flexible elastomeric material are secured against the head of a user, each enclosing an ear in an air tight chamber, to close down the transmission paths available to sound waves. The shells are impervious to air, and flexible to conform to the head when secured by the headgear in which the shells are embedded. Each shell is provided with a rim, sufficiently flexible to deform and deflect into complete, sealed contact with the head.
