Study Details

Brief summary:

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
