Design outcomes

Primary

Measure	Time frame
Speech recognition scores are assessed through BKB sentences at fixed signal to noise ratios (SNRs) and consonant-nucleus-consonant (CNC) words at seven timepoints: 1. Before training 1 (baseline 1) 2. 1-2 weeks after timepoint 1 (baseline 2) 3. After receiving training 1 (effect of training 1) 4. 1-3 months after timepoint 3 (retention of effects of training 1)* 5. 1-2 weeks after timepoint 4 (baseline without training period for training 2) 6. After training 2 (effect of training 2) 7. 1-3 months after training 2 (retention of effects of training 2)* *For recruitment and testing logistics, the retention period at the first site was set at 3 months, but shortened to 1 month for the other 2 sites.	—

Secondary

Measure	Time frame
1. Behavioural measures of spectral resolution is measured using spectral-temporally modulated ripple test 2. Visual and auditory attention is measured using integrated visual auditory continuous performance test 3. Sustained attention and inhibition control measured using Victoria Stroop test 4. Working memory is measured using reading span test 5. Speed of processing is measured using Victoria Stroop, letter monitoring and semantic judgement tests 6. Phonological representations is measured using rhyme judgement test 7. Speech hearing, spatial hearing, qualities of hearing, and listening effort is measured using the SSQ12 questionnaire 8. Confidence in management of communication situations in simple and complex noisy environments is measured using the SESMQ questionnaire 9. Communication apprehension across four communication contexts: public, small groups, meetings and interpersonal encounters is PRCA-24 questionnaire 10. Functional health and well-being is measured using SF-36 questionnaire 11. Quality of life aspects of Quality of Life scale The above are measured at seven timepoints: 1. Before training 1 (baseline 1) 2. 1-2 weeks after timepoint 1 (baseline 2) 3.
