Schoolchildren from class 1b visited the Museum of radio and television. Here children had an educational activity "Talking box" about great-grandfather of CD, the first machines and moving pictures. It was very intersting for pupils to hear and see, touch and feel and experience. The children even tried to call for help using a Morse-code. Pupils got to know a lot and met the effects of noise on man.
The school nurse led the activity about noise damage on children. She showed a movie and let children themselve to feel how noise affects in a few minutes. Finally, the first formers measured up noise decibelus.
