Design outcomes

Primary

Measure	Time frame
The main outcome measures are the detection threshold for speech distortion and preference for different degrees of noise reduction. We will look for relations between those measures and other audiological characteristics (pure tone threshold, acceptable noise level, frequency resolution, temporal acuity, or speech intelligibility).	—

Secondary

Measure	Time frame
