Selection of test-setup parameters to target specific signal-to-noise regions in speech-on-speech intelligibility testing.

Objective: To investigate the magnitude of the change in speech-reception threshold (SRT) provided by altering four different test-setup parameters. Furthermore, to determine whether these changes in SRT are of a sufficient magnitude, such that they can be used to design a test-setup in future experiments that target a predefined signal-to-noise ratio (SNR) region. This could be particularly important if the test contrast investigated is confounded with test SNR.

Danish reading span data from 283 hearing-aid users, including a sub-group analysis of their relationship to speech-in-noise performance.

Objective: This study provides descriptive statistics of the Danish reading span (RS) test for hearing-impaired adults. The combined effect of hearing loss, RS score, and age on speech-in-noise performance in different spatial settings was evaluated in a subset of participants.

Design: Data from published and unpublished studies were re-analysed.
