For international conferences, where representatives from different nationalities participate, it is of greatest importance all participants to listen to a language they understand all the time. Therefore, it is mandatory to use a system allowing simultaneous (synchronous) interpretation to the floor language used. This is achieved by using professional for simultaneous interpretation, where the interpreters are accommodated. The translation of the different languages is distributed in such a way that each of the delegates could choose, by means of a special device, the language he/she understands.
Infrared Signal Distribution
The most effective way of distribution of interpretation is through use of infrared (IR) system. It is wireless, which gives the delegates full freedom of movement. However, this means also full confidentiality of the information as the distributed signal cannot go outside the room. The new systems offer better than ever digital audio quality without any disturbances from the lighting in the room or other external sources of noise. This is also the only system, which is not affected by the safety systems of radio jamming used by the security services. This is what makes it the only system which could be used for meetings and events at highest level.
Confidentiality of Discussion within Conference hall Framework
The conference discussions often affect sensitive topics and confidential information is shared there. In such cases it is very important the audio broadcasting not to threaten the security of the information. As the infrared rays do not pass through opaque materials, from which the walls are built, the conference hall itself serves as a barrier for this type of rays and protects from unwanted interception. All other RF (radio) systems, offered to the market, do not cover this requirement and could be listened to remotely without the knowledge of the organizers, lecturers and delegates in the room.
Quality of Sound
The digital infrared system offers significantly improved quality of sound. The better technology of compression and the higher signal/noise ratio lead to much bigger clarity of the accepted signal and high speech intelligibility as well as full resistance to disturbances from sunshine and the lighting in the room. Because of the greater distinctness, its use is less tiresome for the participants in case of a long use. This leads to increasing the capability of the delegates to preserve their concentration during prolonged conference meetings.
Freedom of Movement of Delegates
By using the infrared system, the delegates receive significant freedom of movement within the frames of the conference hall. As the translation is spread in the air and the delegates are not physically connected to the system, they could move freely within the frames of the hall restricted only by its walls. The receivers and the earphones are light, easily portable and unobtrusive.
