Hearing loss, especially for speech perception in the presence of noise, may lead older individuals to withdraw from social situations. While hearing aids help amplify sound and are useful in many situations, they can be ineffective in noisy contexts. The proposed pilot study will evaluate taVNS for improving speech in noise perception in adults with age-related hearing loss.
