    "abstract": "We discuss the structure, physical nature, dynamic genesis of clearly\ndetected diffuse backgrounds (radiations) in the Universe. From the point of\nview of Wave Universe concept it is shown, that observed Backgrounds Hierarchy\n(Polyphony of Universe) is close connected and causely determined by the sound\nvelocity Hierarchy of the physical medium, cosmic (polycomponent) plasma. The\nwell-known Microwave Background (Cosmic Background Radiation - CBR) corresponds\nto the F[3] Background, that is characterized by the calculated sound velocity\nC*[3]=11.483 km/s, by the calculated temperature T*[3]=2.9 grad.K and by\nwavelength of the radiation intensity maximum lambda*[3]=1 mm.",
