Compliance
Along with the inclusivity and positive impact these systems foster, many public venues are also required by law to provide assistive listening solutions for those who need them. For instance, the Americans with Disabilities Act (ADA) mandates that spaces like theaters, lecture halls, and stadiums offer assistive listening devices (ALDs) to their patrons. Although accessibility guidelines vary from country to country, they universally emphasize the legal responsibility to accommodate individuals with hearing loss.
