Design outcomes

Primary

Measure	Time frame
The main study parameters in the study are: (1) the pupil response evoked during listening to speech in noise and (2) the brain activation during listening to sentences in noise. Sentences will be presented in noise, using a wide range of signal-to-noise ratios (SNRs) covering very low to high comprehension levels.	—
