Presentation in a noisy room? Guided tour or museum tour of a location where no noise may be made? Then a whisper set or tour guide set will do the trick. This allows the speaker to make himself understood while maintaining a normal or soft volume. The audience follows the presentation via their own headphones. Each participant can adjust the sound to the desired volume. A whisper set can also be used by an interpreter to provide a translation. In this case, the translator will interpret the presentation via the wireless microphone. The translation can then be heard by the participants via the headphones.
