Sports centres and associations

There is a trend developed in sport halls to use aids in order to improve the overall sport experience of all the participants of a sport event, and to make it easier for external audience to watch the sport event. 

For this purposes, adequate sound is of enormous significance so that the communication between the announcer and the audience, although one-way, is by no means compromised. 

In addition, times when sport venues only had audio equipment are going to oblivion. Today, a great number of such objects have LED screens which are used for commercial purposes.
