The German Institute of Hearing Aids (Deutsches Hörgeräte Institut GmbH) in Lübeck is a test house accredited by the Deutschen Akkreditierungsstelle (DAkkS) according to DIN EN ISO/IEC 17025 and recognized by the Zentralstelle der Länder für Gesundheitsschutz bei Arzneimitteln und Medizinprodukten (ZLG) according to the Regulation (EU) 2017/745 or Medical Device Regulation (MDR). The institute has laboratories and acoustic test rooms for the homologation of hearing aids and for research. For some tests, the certificates can also be issued in English. An example is the test according to IEC 60118-0, which includes not only the signet of the DAkkS and ZLG but also the ILAC signet.



Our comprehensive facilities and equipment allow the testing of various devices and transducers from the area of hearing acoustics, e.g., as air- and bone conduction hearing aids, eardrum contact transducers, active middle ear implants, hearables, hearphones or hearing protectors. The focus of our laboratory activities is the testing of devices for approval in group 13 (hearing assistive devices) of the list of aids ("Hilfsmittelverzeichnis") issued by the National Assosiation of Statutory Health Insurance Funds (GKV-Spitzenverband).
