Telesonic lorgnette, a hand-held miniature radio receiver, 1955-1960
Telesonic Lorgnette, made by A&M Hearing Aids Ltd
In the 1950s transistors and miniaturised circuits made possible the manufacture of compact radio receivers light enough to be portable. The telesonic lorgnette was a device for receiving personal audio commentaries in museums and galleries from low-power radio transmitters with a very short range. Examples of this design were used experimentally in a few Science Museum galleries in 1961. The lorgnettes were returned at the end of the experiment, but this specimen, obtained from BT in 2004, enables the Museum to recall a pioneering test of a now widespread facility.
