Earring Receiver for Vacuum Tube Hearing Aid Throughout history, women have wanted invisible hearing aids. Thus, a fair amount of ingenuity went into hiding the larger hearing aids of previous years. One such invention was to hide the hearing aid receivers inside special earrings so people would think you were wearing earrings rather than hearing aids. This earring receiver is from the decade of the 1940s. It worked with a number of makes and models of vacuum tube body hearing aids available then. Since people in the 1940s typically only wore one hearing aid with one receiver (left), a matching dummy earring (right) was worn on the other ear. This picture shows the front of the earrings, the ear mold and the cord that plugged into the body aid. |
