“Comparison of two measurement procedures to evaluate wireless remote microphone systems in clinical practice”
Speech intelligibility in reverberant environments and in noise is a frequent major problem for people with hearing impairment. In these difficult settings, the exclusive use of hearing aids often is not sufficient so that wireless remote microphone systems (WRMS) can be a good support. These systems bridge the distance between speaker and listener, and can reduce the influence of reverberation while increasing the SNR.
Although the advantages of WRMS are well known, in a number of situations, it seems useful to individually measure their performance. To this end, the German Institute of Hearing Aids (DHI) has developed a measurement procedure, which has also been incorporated into a recently published EUHA guideline.
In this lecture, the application of this measurement procedure in the clinical environment of the Lübeck University Hospital (UKSH) will be presented. I shall explain what kind of set-up was necessary and how the method performed with different patients. Furthermore, the effort associated with, and the results of, this new method will be compared with a procedure commonly used at the UKSH. These results demonstrate that, although the new method emulates a realistic hearing setting, it is nevertheless easy to apply in practice.
