Back in 1992, Auditdata was founded as a joint venture between Danavox (now GN ReSound) and Claus Bak Petersen. The company was dedicated to the development of software applications for the health sector - modules for programming digital hearing instruments and technical and administrative software systems covering all functions in a hearing clinic.

Soon Auditdata had developed the AuditBase System, which provided advanced software for hospital-based audiology clinics.

Today, this system is the leading software system for audiology clinics in public hospitals and interfaces client records, scheduling and audiological diagnostics with central medical record systems.

Most hospital hearing clinics in Denmark, Sweden, Norway and Great Britain now use AuditBase for storing all audiologic and hearing instrument data. In fact, in Great Britain alone, there are more than 100 AuditBase installations and in excess of 1,400 users.

In 1999/2000, Auditdata went on to develop a similar system for use by hearing aid dispensers. Aimed exclusively at the German market, Mirage System was supported by a German subsidiary.

Auditdata was managed by Claus Bak Petersen as CEO until 2000 when he sold his holdings in Auditdata to GN ReSound. Subsequently, Auditdata joined the GN Otometrics company in 2003 as a product division.

Today, Claus Bak Petersen has repurchased the company and is, via the company Sebjerggaard ApS, CEO and owner of Auditdata A/S.
