About the book: 2021 / The study is devoted to the history of the art of sound and musical technology in Russia and the USSR in the first half of the 20th century. The developments of that time in the field of sound, unknown to the general reader for a long time, are still amazing now, almost a hundred years later.

The unifying leitmotif of the book is a look at the history of Russian sound culture from the point of view of media archaeology..
