**9. Acoustics optimization in multimedia classroom as an application second conclusion**

The presented procedure of the analysis, simulation and measurement of the sample multimedia classroom, indicates a need for professional design and supervision of the performance of multimedia classrooms considering their ever-growing use from the point of view of long life learning (LL) that is lengthy and frequent stay in them. Such a statement is very important in the case of adult education since they tire more quickly (especially if they are strained in order to hear better and understand speech) than the younger population involved in lifelong learning, that is, in-service teacher training. This is also very important for handicapped groups (partially sighted people and people with partial hearing abilities) involved in long life learning. Furthermore, all classrooms used for foreign language learning should have strictly defined adequate acoustic conditions, also confirmed by this simulation (optimization).
