Sonotone (hearing aid)
Sonotone Corporation was a hearing aid manufacturer that was started by Hugo Leiber[secondary source needed], inventor of the bone conduction receiver,[1] in New York City in 1929.
Overview
[edit]The company was a leader in the hearing aid industry until multiple buyouts ending in 1970 led to the abandonment of the manufacturing plant.[2] It was temporarily revived in 1987 but had closed again by 2005.
Notable models of Sonotone hearing aids include the Sonotone 1010 in 1952 with a transistor and two vacuum tubes.[3] By 1960, in addition to hearing aids, Sonotone manufactured nickel cadmium batteries, loudspeakers, and hand held microphones.
