Vogt had already developed his idea of ​​the sound film in 1905 . Georg Seibt , in whose company he was employed, was not interested in the new technology. Together with Joseph Massolle (1889–1957) and Joseph Benedict Engl (1893–1942), Vogt founded his own company, the Tri-Ergon, on July 1, 1919 in Berlin-Wilmersdorf .

During the implementation of their sound film system, the three technicians applied for over 150 patents. In addition to microphones, loudspeakers and photo cells, electronic tubes also had to be specially developed, as the tubes available at the time were not sufficient due to their low slope . On September 17, 1922, the first light-sound film was shown to the public in the Alhambra film theater in Berlin on Kurfürstendamm. After a lack of German success, the sound film patents were sold to the American William Fox . This brought the sound film to world renown from 1928.

The community of inventors was dissolved and Vogt founded his own laboratory in 1927. Around 1932 he developed the Ferrocart and is therefore considered to be the inventor of the high-frequency coil with a magnetic core. The Mende company in Dresden was the first to install the new material on a large scale in their radio receivers, thus introducing a new development in reception technology. In addition to this invention, Vogt was also instrumental in the development of the static loudspeaker and later - quite incidentally - in that of the convection electric cooker. The Vogt company he founded in 1934 is a company for electronic components that still exists today under the name Sumida AG .

In 1985 the cinema documentary "Wurlitzer or the Invention of the Present" by Antje Starost and Hans Helmut Grotjahn was made. He "captivates with the intensity of his cinematic language" and tells the life story of Hans Vogt "in an idiosyncratic way between the genres of documentary, feature film and essay". (Ulrich Gregor, Berlin International Film Festival 1986)

Hans Vogt was a supporter of Silvio Gesell's free economy . He was one of the co-founders of the Freiland -freield-Bund , which was initiated by the former Roman Catholic priest Paulus Klüpfel . To commemorate him, Vogt published a collection of writings and letters in 1967 under the title Inside is the infinite will of the world. The notes of Paulus Knüpfel in Erlau near Passau appeared.
