Noise at work can cause other problems such as disturbance, interference with
               communications, difficulties with concentration, fatigue, tension, and irritability – all
               of which may also cause stress.
                      An emerging problem is voice loss due to the necessity to speak in noisy

               environments and may affect, for example, teachers, lecturers and call center workers.

                                                            roads for heavy traffic; separating out incompatible
                                                            functions
               Education and information
               Raising public awareness                     Informing the public on the health impacts of noise,
                                                            enforcement action taken, noise levels, complaints

                      There are next types of facing materials: fiber; basalt fiber; mineral wool. The
               choice of sound-absorbing materials and structures depends on the noise spectrum
               and the type of room.
                      The local methods of noise control at the factories, such as insulating covers,
               screens, cabins, are used.
