Background:

The Freiburg monosyllabic test has not been adaptively used yet. Therefore, in this study an adaptive procedure, which has proved itself in sentence tests, was transferred to the Freiburg monosyllabic test in noise. The results of the new procedure have been compared with the Oldenburg sentence test as standard of the sentence tests.

Methods:

A number of 40 otologically normal subjects were examined both by adaptive Freiburg monosyllabic speech test and by Oldenburg sentence test in randomized order. Results were analyzed with respect to time requirement, possible gender differences, the influence of test order and correlation of test results.

Results:

The time requirement for the adaptive Freiburg monosyllabic speech test was significantly higher than for the Oldenburg sentence test. Concerning possible gender differences or the influence of test order no significant differences of the test results could be shown. The mean signal-to-noise ratio for 50% speech discrimination of the Oldenburg sentence test was significantly smaller than of the adaptive Freiburg monosyllabic speech test. Between the results of both tests no correlation could be shown.

Conclusion:

The Freiburg monosyllabic test can not only be used for quantifying the discrimination loss as hearing loss in percentage terms, but also to measure the 50% speech recognition threshold with an adaptive algorithm. However, the procedure of the adaptive Freiburg monosyllabic test is more time-consuming than the one of the Oldenburg sentence test.
