Multi-color variably attenuating earplug

The present invention provides an earplug having a plurality of visual zones. In one embodiment, the earplug includes a first visual zone, a second visual zone, and a third visual zone. The first, second, and third visual zones each comprise continuous longitudinal color bands each of which extends completely around the circumference of the earplug. In one embodiment, at least the second visual zone intermediate the first and third visual zones is formed of a color which is distinctly different from the colors of the other visual zones. In another embodiment, the first, second, and third visual zones each have one color which is distinctly different than the other colors. Accordingly, the first, second, and third visual zones comprise visual zones which permit an observer or the wearer to immediately ascertain the depth of insertion of the earplug by simply viewing the earplug. In one aspect, this permits a safety officer or other individual, including the wearer, to easily determine whether the wearer is complying with existing safety rules and regulations. In another aspect, this permits the wearer to determine whether a proper fit exists between the earplug and the ear canal because each of the visual zones indicates the degree of insertion into the ear canal.
