Getting accommodations for people with hearing loss for jury duty has been an issue for a very long time. See this article by Brenda Battat, former executive director of HLAA, written back in 2011: https://www.hearingloss.org/wp-content/uploads/Battat_Column_MarApr_2011_HLM.pdf?pdf=2011-hlm-mp-bbattat NY State, which does not have any automatic exemptions, has a brochure that includes a brief look at case law regarding jury duty for people with disabilites. https://ww2.nycourts.gov/sites/default/files/document/files/2018-08/jurors-w-disabilities02-03-14-1.pdf 

Inclusion of people with disabilities in jury duty is covered under Title II of the Americans with Disabilities Act, so you can file a complaint with the US Department of Justice. How to File an ADA Complaint 

You can also do some local investigating and education the local court system - in fact, you have already started. The local court system should hear about what you have learned so far. It may be a long process of finding the right people and how to make change happen, but your actions could result in a more enlightened court view of accommodating people with hearing loss. 

Thanks, Carol for starting this thread. If others have had experiences in jury duty or finding ways to ensure the court provides accommodations, please do chime in.
