Hearing aids (and technical audiology)

DELTA – a part of FORCE Technology is the world-leading test house for hearing aids. Since 1964, we have built up unique knowledge about hearing aids and testing of hearing aids, through which we ensure our clients can establish their products on the international market

To remain at the forefront of developments in the testing of technical audiological equipment, we are a member of several IEC/TC29 working groups involved in standardisation. We are involved in collaboration groups that are managed by the industry, and we share knowledge with the private and public sectors involved in hearing health care.

Furthermore, we function as a knowledge centre for technical audiology and approves and certifies over 300 private hearing aids dispensers in Denmark on behalf of the Danish Ministry of Health (for more details, visit www.audiologi.dk).

Our knowledge is sought by the public sector, the hearing health care sector, manufacturers, and academia.

We provide services within the testing of hearing aids, screening equipment, and auxiliary technical hearing aids, and we make our extensive expertise available as an advisor in connection with certification and accredited testing.
