In order for a judge to be fair and impartial when communicating to the participants of a courtroom, it is essential that the judge's message can be heard by all - including those participants who have a hearing disability, or those who do not speak the court's native language. Infrared systems and FM Systems from manufacturers such as Williams Sound and Listen Technologies are designed for such purposes, accommodating both the hard of hearing listener, and providing language interpretation for courtroom participants that require it.
Here's how the IR System works: the judge or clerk speaks into a microphone, which sends the message to a modulator; the modulator then drives one or two infrared emitter panels, which are strategically pointed toward the courtroom audience. The emitter panels transmit the judges message by way of an infrared signal (similar to how a TV remote works). Listeners in the courtroom wear body-pack style receivers equipped with headphones (or earphones); they pick up the judge's message and adjust the volume to a comfortable listening level. The Infrared System technology keeps the transmitted message from being transmitted outside the opaque walls of a courtroom, which increases security - often an important element of courtroom proceedings. This also eliminates any interference from adjacent courtrooms that might be using the same technology. Infrared Systems have the ability to transmit more than one signal at a time. This gives the court the ability to provide simultaneous language translation services for its participants.
Here's how the FM System works: the speaker would use a microphone and a transmitter to transmit the audio to the audience via an FM signal. The audience members could then hear the speaker better (if they are hard of hearing) or could hear their native language (if used for language translation) via their headphones and receivers. Please note that these systems could allow audio from the courtroom to be transmitted through the walls, so they are not as secure as the IR systems. |
