Sonotone (hearing aid)

Sonotone Corporation was a hearing aid manufacturer that was started by Hugo Leiber, inventor of the bone conduction receiver,[1] in New York City in 1929. It 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 cadminum batteries, loudspeakers, and hand held microphones,
