The Medical Acoustic Instrument Company (later shortened to MAICO) was founded in 1937 in Minneapolis, USA.

MAICO designed and produced the first hearing test instrument with a “zero reference level”, coining the term “audiometer”. For the first time it was possible to accurately measure hearing loss.

In 1991 the company merged with the audiometer division of Robert Bosch GmbH/Berlin to support international operations. A traditional and innovative company had emerged.

Since 1995, MAICO has been part of William Demant Holding.
