If you want to communicate a message to your companion, you need to be certain that he understands your language. If you don’t speak the companion’s language well, you would need the support of translators or specialized equipment, widely available on the modern market.
If communication is impossible because your companion speaks a language different from yours, it means that you cannot exchange personal, as well as business, information. As you know, the world is developing in the direction of globalization and everybody wants to take their business into different countries. In these conditions, a language barrier becomes one of the main obstacles. Suppose you need to organize a business meeting to discuss development plans and strategy of a company with representatives from different coutnries. You would need to ensure that people that come from different countries are able to communicate with each other. In order to solve this problem, you need to acquire specialized equipment and use the services of translators (the costs of the services of a translator are usually discussed in advance).
Once the meeting starts, a group of translators placed in a separate room begins their work. Their translation is transmitted into special headphones. Listening and translating at the same time is quite a difficult job. During this process, the speaker’s voice speaks into the microphone which transmits the sound to the translator working with a transmitter. A transmitter is a device that serves as a small radio station that sends the signal outside the conference hall. If the meeting is confidential, you can ensure additional secrecy in order to prevent unsanctioned access to the transmission. Usually, these measures are implemented for governmental meetings and UN assemblies.
Infra-red transmitter used in these cases is working on invisible light waves that transmit the signal all over the premises. Another type of transmitter works in the same way as an FM. In this case, a weak signal of particular frequency is transmitted and distributed across the entire conference hall. If people who speak different languages are participating in the meeting, a particular frequency or channel is selected for each language and listeners receive the translation that they need by using headphones with the transmitter. This way, use of specialized equipment would serve your purpose. You should ensure, also, that you’re acquiring it from a well-recommended company.
