About this trial
Researchers are doing this study to understand why hearing aids often work well in controlled laboratory settings but don't provide the same level of benefit in everyday noisy environments. The questions they hope to answer are:
* What factors contribute to hearing aid benefit in noisy environments * What factors limit hearing aid benefit * How do real-world factors interact with common hearing aid settings
Participants will complete:
* Hearing and listening tests * Memory and attention assessment * Surveys on their Smartphone

Trial outcomes
Primary outcomes
1
Compare effectiveness of hearing aid signal enhancement on speech perception
Participants will hear 3 different, 5 minute listening scenarios and answer the same survey questions for each. They will rate perception from 0% (understood nothing) to 100% (understood everything). Percentages will be compared across the 3 scenarios.
Time frame
1 week2
Compare effectiveness of hearing aid signal enhancement on listening effort
Participants will hear 3 different, 5 minute listening scenarios and answer the same survey questions for each. They will rate how hard they had to work to understand what was said from 0% (no effort) to 100% (extremely hard). Percentages will be compared across the 3 scenarios.
Time frame
1 week3
Compare effectiveness of hearing aid signal enhancement on listening comfort
Participants will hear 3 different, 5 minute listening scenarios and answer the same survey questions for each. They will rate how comfortable it was to listen from 0% (very comfortable) to 100% (very uncomfortable). Percentages will be compared across the 3 scenarios.
Time frame
1 week4
Compare effectiveness of hearing aid signal enhancement on sound quality
Participants will hear 3 different, 5 minute listening scenarios and answer the same survey questions for each. They will rate the sound quality from 0% (very poor) to 100% (excellent). Percentages will be compared across the 3 scenarios.
