What Is a DHI Certificate?
The DHI (Deutsches Hörgeräte Institut, the German Hearing-Aid Institute) certificate is an approval that hearing-aid manufacturers apply for to test, evaluate, and certify their products. The certificate is issued by the institute following assessment of a hearing aid's conformity, performance, and quality. It is a significant document for manufacturers and distributors who want to place hearing aids on the German and international markets, because retail channels and public-health systems in Germany commonly require DHI-certified products.
How to Obtain a DHI Certificate
Manufacturers and distributors applying for DHI certification must evidence that their hearing aids meet the defined technical standards. The application runs through the following stages:
- Application: the manufacturer or distributor files the DHI application. The application identifies the product, the intended use, the hearing-aid categories covered, and the technical features to be assessed.
- Product testing: the German Hearing-Aid Institute tests the submitted hearing aids. Tests cover acoustic quality, hearing performance, durability, and reliability.
- Certification: hearing aids that pass the test panel receive the DHI certificate, confirming the product's quality and conformity.
- Periodic review: DHI-certified hearing aids are reassessed periodically to maintain the validity of the certificate.
Which Products Does DHI Cover?
The DHI certificate applies to hearing aids intended for the German and broader European markets. Because the certificate is trusted by dispensers, health-insurance bodies, and consumers in Germany, it has a direct effect on a hearing-aid manufacturer's ability to compete in that market.
DHI Certificate Fees
Fees depend on the number of hearing-aid models under review, the test panel required, and whether the technical file is already in German-market format. Ask for a quote once the scope is confirmed.
