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:
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:
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.

| STM Training | Behavioral | This condition consists of an up/down spectral-temporal modulations (STM) presented both in quiet and with competing background noise |
|
| Measure | Description | Time Frame |

| Digits-in-Noise (DIN) Task | The DIN tests the ability to identify a series of digits in varying levels of background noise. | Pre-test (day 3), mid-test (day 20), post-test (day 36), follow-up (day 66) |
| Spatial Release From Masking (SRM) | Tests the ability to identify a target talker in the presence of competing speech signals that are either colocated or spatially separated from the target. | Pre-test (day 3), mid-test (day 20), post-test (day 36), follow-up (day 66) |
| Dichotic Sentence Identification (DSI) | The DSI test simultaneously presents two nonsense sentences, one to each ear. Participants indicate two sentences heard from a list of 10 alternatives. | Pre-test (day 3), mid-test (day 20), post-test (day 36), follow-up (day 66) |
| Measure | Description | Time Frame |

| Revised Hearing Handicap Inventory (RHHI) | The Revised Hearing Handicap Inventory (RHHI) is a self-assessment questionnaire designed to evaluate the perceived social and emotional effects of hearing loss on an individual's daily life. | Pre-test (day 3), mid-test (day 20), post-test (day 36), follow-up (day 66) |

| 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. |

| Auditory Visual Divided Attention Test (AVDAT) |
Auditory Visual Divided Attention Test (AVDAT) is a test of working memory that compares conditions when attention is to just a single modality (auditory or visual) or divided across modalities. |
