Outcome Measures

Primary Outcomes (1)

  • Oldenburg Sentence Test

    The Oldenburg Sentence Test (OLSA) is an audiometric test for determining the speech recognition threshold in quiet and in noise. Sentences of the form name - verb - numeral - adjective - noun are used as speech material. The sequence of words is a random combination from an inventory of 50 words in total. The design of the test prevents memorization of the sentences, so the OLSA can be repeated as often as desired.

    Estimated Time Frame 2 weeks (Test conducted at second lab session).

Secondary Outcomes (3)

  • Freiburger Monosyllabic Speech Test

    Estimated Time Frame 2 weeks (Test conducted at second lab session).

  • Match-to-Target

    Day 1 (Fitting procedure with real-ear measurements is done at first lab session)

  • Basic user need documentation

    One session of approximately 2 hours.
