Verbal communication is one of the most important aspects of human hearing. In everyday life, almost all conversations take place with interfering noise so that understanding speech in noise is particularly important for everyday listening. For most hearing impaired people, it is precisely the understanding of speech in noise that is especially difficult, and a key objective of hearing aid provision is to improve speech understanding in noise. The diagnosis of a hearing impairment and the evaluation of hearing aid provision therefore requires suitable audiometric test methods.

HörTech is regularly involved in the development of new speech audiometric tests and has a particularly large amount of expertise in this area. The spectrum of the developed procedures ranges from screening tests via diagnostic test procedures to test methods for research purposes. Of particular note are the international Matrix Tests and Digit Triplets Tests that were developed in cooperation with and coordinated by HörTech in over 15 languages and are available to researchers, audiologists or other users. Other test procedures are in preparation together with international development partners. If you are interested in any speech audiometric procedure in a language not yet available, please do not hesitate to get in touch with HörTech.

In addition to the diagnostically oriented testing methods, special measuring methods for various other purposes can also be developed. For example, HörTech employees were involved in the development of language tests for the consideration of cognitive aspects of hearing or the testing and evaluation of signal processing algorithms. We look forward to challenging new tasks!
If required, licenses for the use of language materials of individual language tests can be granted. We are happy to assist with any requests.
