The guides may speak in a normal tone of voice, without the necessity of projecting their voice and speaking over other colleagues; Every visitor gets to enjoy their visits much more as they are able to hear the guide’s description, making them feel freer in the visited places;
Visitors keep more information from the guides, which is an important advantage regarding the promotion and the quality image of the visited places.
It also avoids that monuments, tourist centres and religious spaces become noise focus, anytime more than two groups meet.
There is no need for the guides to wait for the entire group to start the description, which affects the visit’s progress and quality;
There is no chance for group intruders, as only the group enjoys the system allowing to hear the guide’s description.
