Acousticon A-152 (International) Vacuum Tube Hearing Aid The Acousticon A-152 (International) hearing aid was produced by Dictograph Products, Inc. of New York in 1950. It featured a case of gold anodized aluminum. The hearing aid measured 3⅛” by 2⅜” by 13/16” and weighed 5˝ oz. with the batteries installed. |  | Click picture for larger view | | |   | | | |

| The Acousticon A-152 could also come with a bone conduction transducer. A head band (not shown) held the transducer tight to the bone behind the ear which allowed the wearer to hear via bone conduction. |  | Click picture for larger view | | | |

| Another most interesting feature of the Acousticon A-150 (and also the A-90, A-100, A-152) was that instead of plugging in the Radio, you could also plug in an external microphone that looked just like a wrist watch. This allowed you to keep the body aid hidden--because the sound would then be picked up by the microphone hidden in the watch-like casing. A cord ran up the sleeve to the hearing aid in an inside pocket. Here is an ad (bottom left corner) for this "Wrist-Ear" external microphone published in the Sunday Morning edition of The Democrat and Leader newspaper of Davenport, Iowa on July 17, 1949. |  | Click picture for larger view | | | |
