The bill aims to assess the impact of providing over-the-counter hearing aids to veterans by establishing a demonstration project for a two-year period. It specifies eligibility criteria for veterans and outlines the project's design, including measurement of benefits and consultation with stakeholder organizations. The Secretary of Veterans Affairs is required to submit interim and final reports to Congress on the progress and findings of the project. Additionally, the Comptroller General will conduct a study on hearing aid benefits for veterans with mild-to-moderate hearing loss and submit recommendations to Congress within 18 months.
