Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* Does transcranial stimulation improve speech-on-speech understanding in people who struggle with this task?
* Does transcranial stimulation enhance the benefits of a commercially available auditory training program?
Researchers will compare transcranial stimulation to sham stimulation (no stimulation is applied during the listening task).
Participants will:
* Receive login information to an online auditory training program to complete at home over 2 weeks
* Visit the laboratory 4 times to receive transcranial stimulation while listening to speech-on-speech: once before at-home training, two times during the at-home training period, and once after at-home training has ended

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Active transcranial stimulation
This group will receive active transcranial alternating current stimulation that matches the envelope of the target speech.
Transcranial current stimulation
The transcranial alternating current stimulation is delivered during the speech stimulus and the current matches the envelope of the target speech
Auditory training
An at-home auditory training program that adaptively and interactively trains the listener in degraded speech, cognitive skills, and communication strategies
Sham stimulation
This group will receive transcranial stimulation that ramps on and off before the speech is presented.
Auditory training
An at-home auditory training program that adaptively and interactively trains the listener in degraded speech, cognitive skills, and communication strategies
