Abstract
A composite reusable sound attenuating or transmitting device, especially an ear plug, is formed from a core, about which is adhered a strip of slow recovery foam. After each use of the device, the strip of foam is generally removed and discarded; typically, a new strip is applied the next time the device is used.
