Interventions

• STM Training — BEHAVIORAL
  This condition consists of an up/down spectral-temporal modulations (STM) presented both in quiet and with competing background noise
• Speech Training — BEHAVIORAL
  Participants will train on the identification of three sets of speech stimuli of increasing linguistic complexity: individual phonemes (vowels), spondaic words, and matrix sentences.
• Mixed Training — BEHAVIORAL
  This condition involves both the STM and the speech training, described above, and an additional module training localization.
• Gamified Training — BEHAVIORAL
  This uses auditory training within a game experience where players control a game avatar (the "wisp") that appears to fly through a landscape. Players were asked to help the wisp avoid obstacles or choose from among options based on a variety of sound cues.
• Foraging Training — BEHAVIORAL
  This adds a component to the game where participants navigate the wisp to the location on the screen that relates to the target stimulus. The concept here is that searching for targets with manual movements, ecologically stimulates sensori-motor loops where the actions of the participants generates the auditory stimuli that are heard.

Study Details

The goal of this clinical trial is to learn how Auditory Training (AT) may help people better understand speech in noisy environments. As people get older, it becomes harder for them to hear speech clearly when there is background noise. This can be frustrating, and it can affect their independence and quality of life. AT is often used to support people with and without hearing loss, especially when a person is not a good candidate for a hearing aid or when amplification from a hearing aid does not improve performance. The investigators want to gather reliable data to understand how AT works and what affects its success. The main questions the trial aims to answer are: * How do different types of sounds influence the effectiveness of auditory training? * Which auditory training approaches are most successful in improving speech understanding? * How do personal traits impact the results of auditory training? The investigators will study a large and diverse group of 1,260 participants, including both young and older adults, to evaluate various auditory training approaches. You will: * Take part in auditory training sessions that include different types of auditory tasks. * Complete tests that measure how well they understand speech in both quiet and noisy settings. * Complete surveys on personal data like demographics, hearing challenges and other factors to help researchers understand what might influence training results. The investigators will measure and compare the results of these approaches to find out which ones are most effective. This could help people who are at risk of cognitive decline, like those at risk for Alzheimer's disease.
