Thank you for your response. You are not alone. If you depend on hearing aids or implants it could be very helpful to know how to make your devices work with hearing loops that are installed in public spaces. Attached is the "request-for-info" card that was created by the HLAA. The link to HLAA from maryjax is full of resources. That's the national site for Hearing Loss Assoc of America and you can also find out if there is a local chapter near you.
