Beltone "Carillon" Eyeglass Hearing Aid The Beltone "Carillon" eyeglass hearing aid was made by Beltone Electronics Corporation of Chicago, IL in 1958. All the electronics were housed in the behind-the-ear part of the temple piece. Thus, these eyeglass hearing aids could be configured for one ear, or both ears. The hearing aid pictured here is housed in the left temple-piece. The thick right temple-piece is a dummy made to look the same as the other side. |  | Click picture for larger view | | |   | | | |
