Thank you for your feedback and question. Audio Induction (Hearing) Loop technology is indeed an old technology. It is also true that the installation of loop systems is not as consistent across the US as in many European countries. Unfortunately, prior to 2006, some of the loops installed in the US delivered less-than-satisfactory performance. However, in 2006, standards for loop system performance were heavily revised by the International Electrotechnical Commission (IEC). The more complex requirements of the IEC60118-4 increased performance standards for loop systems in any assistive listening application. Adopted around the world as the reference for performance, the new code impacted the specification, design, installation and maintenance of the systems to a point that many part-time installers left the profession. (Hint: if an installer does not guarantee to commission a loop project to meet IEC60118-4 standards find a new installer!) In 2010, the ADA rules for effective communications in public spaces were also upgraded. Since then, you will find that many extremely large theaters have been looped properly and the audio quality is beautiful -- no "dead spots" at any seats. Also, looping for smaller spaces is more popular now, and 1:1 conversational loops have been installed in many places.

@bobbiefriend Same same, audiologist just dismissed my questions and I've never been clear on how it works, or even if my hearing aids are compatible. Or how to turn it on. It's not automatic because I've been in venues with it, but never got any help.
