Longer range FM systems (portable) If the venue of the event exceeds 1000 feet, longer range FM systems are needed. But with great power also comes… more weight. These systems are still portable, though it is more difficult to move them around compared to medium range FM systems.
More power means better cancellation of radio interference, which in turn means more quality in the sound of the interpretation transmitted.
Longer range FM systems are also more cost-effective than medium-range systems for a larger audience.
The biggest drawback is immobility. Yes, longer range FM interpretation systems are still portable but they're not mobile. These transmitters are usually fixed, meaning speakers and attendees can't move too far from them, or they will not hear the speech.
Interpreter booths Interpreter booths are a must for simultaneous interpretation where traditional equipment is used. Interpreters have to be in the venue and it tends to get quite noisy. Having in mind the stress the interpreters have to endure during big conferences, it is very important to ensure they have a sound-proof working environment – that is, interpreter booths.
Interpreter booths can be either permanent or mobile. Both variants are strictly regulated by the International Organization for Standardization (ISO) standards[8] relating to conference interpreting.
As for the shape, interpreter booths come as tabletop booths and as full-size interpreting booths. As the name suggests, the first ones are placed on the top of the table and are great because they're easy to transport and set up. On the other hand, they're open in the back, which means you can't completely ensure comfortable work conditions for the interpreters because these booths are not fully sound-proof.
Full-size interpreter booths are like little houses. They have walls, floors, ceilings, doors, and their own ventilation systems. Usually, they can fit at least two interpreters and larger booths can fit even four. Naturally, such interpreter booths are much harder to transport and assemble and require at least a couple of technicians for this task.
Interpreters need to have a clear view of speakers, the podium and presentations.[9]
Interpreters also need great access to the Internet.
They also need to have a sufficient number of power outlets for their laptops, tablets, and any other gadgets they may need to work.
High air quality is a non-negotiable for obvious reasons, too. That's where sensors that measure CO2 step in.
Optimal acoustic conditions, meaning fans should be as quiet as possible and sound insulation from other booths should be close to perfection.
