OLSA – Oldenburger Satztest

Repeatable speech audiometry with sentences
The Oldenburg sentence test determines the speech recognition threshold (SRT) with a precision in the range of ±1 dB. Due to the adaptive level control, the SRT is assessed with one single test list. The sentences are composed with the same structure of five categories (name, verb, number, adjective and noun, e.g. “Peter kauft fünf rote Blumen”). The sentences are created as a seemingly random combination of an inventory of ten words per category which makes it impossible to memorize them. Thus, after a short training, the test can be repeatedly conducted with the same person without affecting the test results.
