Founded in Denmark

Interacoustics A/S was founded in Denmark in 1967 by the Dane Pierre Honore and Michael Davis from New York. The two men met during World War II and decided to set up a business producing and selling hearing equipment for the deaf. The company started out at modest premises, Berrildsvej in Assens. Just five years later in 1972, Interacoustics needed to move to a larger base in an old farm outside the town. By 1978, Interacoustics had outgrown these premises too, and built a new head office at Drejervænget in Assens. Over the following 20 years, production grew and the company continued to expand.
In the 1970s, products at Interacoustics were hardware-based and focused primarily on audiometry. The first audiometer was launched in 1969 and in 1974, the first middle ear analyzer AZ2 was introduced. During the 1980s and 1990s, as the company grew in strength, the rate of development increased. By remaining at the front edge of new technological developments, our products became ever ‘smarter’. Being the only full-line supplier in the field, the products now range from compact handhelds to sophisticated desk units across the fields of balance, audiometry, tympanometry and ABR/OAE.
