Virtual Acoustic Localization Experiment

The present study has the evaluation of a test to measure the localization performance goal . It is about the perception of danger audio signals in everyday listening environments nearby which are reproduced in controlled laboratory conditions. In addition, a dereverberation algorithm regarding speech intelligibility and localization ability is evaluated . The research hypothesis is that the dereverberation of the audio signals can improve speech intelligibility for both normal hearing and hearing-impaired persons. In addition, the binaural dereverberation algorithm should not affect the localization ability in everyday situations.

Primary outcomes

  1. Oldenburger sentence test and localization test with 30 subjects

    Time frame: 1 day

    The impact of a dereverberation algorithm for hearing aids and / or cochlear implants will be checked

Secondary outcomes

  1. Differences in localization ability

    Time frame: 1 day

    By VALE (localization test) can differences in the localization ability between normal hearing and hearing-impaired people be measured
