The effects of dosage and duration of auditory training for older adults with hearing impairment.

This study explored a range of training dosages and durations for a word-based auditory-training procedure for older adults with hearing impairment. Three groups received a different "dose": 2x/week; 3x/week; no training. Fifteen training sessions comprised a "cycle" which was repeated three times for each dosage. Groups that completed training performed significantly better than controls for speech-in-noise materials included in the training regimen, with no significant difference observed between the 2x or 3x/week training groups. Based on these results, as well as prior literature on learning theory, training 2x or 3x/week for 5-15 weeks appears to be sufficient to yield training benefits with this training regimen.
