With a few exceptions, all our courtrooms (in Rockford and here in Chicago) have assisted listening stethoscope type headsets for the hearing impaired.
They are extremely lightweight with excellent sound quality with selectable right, left or stereo sound. They also have a volume gain control knob for the wearers comfort level. Jurors and visitors need only to ask the courtroom clerk for obtaining one while in the courtroom. Sound is picked up from a transmitter up in the front of the courtroom near the ceiling. The unit is worn so the "clear" bubble receiver (or the name on the other model) faces away from the wearers body.
