Company History

Auditdata A/S was founded by Claus Bak Petersen in 1992 as a joint venture with Danavox (now GN ReSound). Auditdata in the 90s: Core business targets audiologists in the health sector.

Auditdata Headquarter in Taastrup DK

Auditdata headquarters lie in the greater Copenhagen area, Taastrup.

From the very beginning Auditdata has been dedicated to the development of software applications for the health sector, including modules for programming digital hearing instruments, technical and administrative software systems covering all functions in a hearing clinic.

Our primary goal when starting up was to eliminate one of the major issues in hospital-based hearing clinic workflow: errors due to multiple systems with no or little synchronization of data.

Tailor-made office management software supports hospital workflows

In 1993, we met the challenge with the launch of Auditbase – tailor-made office management software for the optimization of patient treatment in public sector audiology.

Auditbase has become a standard in hospital-based audiology clinics

Today, Auditbase is helping audiology clinics in hospitals by interfacing client records, scheduling, and audiology diagnostics with central medical record systems. More than 80 % of all hospitals in UK and Scandinavia use Auditbase.

Auditdata in the 00s: Introducing office management for private clinics

In 1999, we introduced Mirage – a system similar to Auditbase for use by private hearing aid dispensers. Aimed primarily at the German market, the Mirage System was supported by a German subsidiary

Change of ownership to GN Resound – and back

CEO, Claus Bak Petersen, sold his holdings in Auditdata to GN ReSound in 2000. Subsequently, in 2003, Auditdata merged with GN Otometrics as a product division. In 2006, Claus Bak Petersen repurchased the company and is shareholder of Auditdata A/S today.
