Transcranial Stimulation Combined With Auditory Training

The goal of this clinical trial is to learn if non-invasive brain stimulation (called transcranial stimulation) can enhance the benefits from auditory training in people who struggle to understand one talker when many people are talking at the same time. The main questions it aims to answer are: * 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
