New York City
The New York City Chapter of HLAA now has an active hearing loop initiative (see here). The association offers a listing of NYC looped facilities here (PDF).
New York has a number of signature hearing loop installations, led by America’s biggest hearing loop project: the New York Transit Authority’s installation of loops at its more than 450 subway booths (see here [PDF]).
Following a successful 18-month pilot program, the New York City Taxi and Limousine Commission approved the voluntary installation of hearing loops in New York taxis (see here). That led in 2012 to the news that, over time, all future New York City taxis will come to have hearing loops--which will be a feature of the new Nissan model (here).
Some of these installations were spearheaded by Janice Lintz, whose Hearing Access Program is dedicated to “helping the world’s corporations, cultural and entertainment institutions, government agencies, and mass transit organizations improve their accessibility for people with hearing loss.” Thanks to Schacter’s efforts, hearing loops can also be found at various other locations around the world, such as the Kentucky Derby Museum, the Ben and Jerry's factory tour, and Virginia’s Chrysler Museum auditorium.
