Our history of home audio systems will take you from the beginning of listening to music around a console radio at home all the way to the streaming audio present, providing context for each change in format and listening style — and hopefully taking you on a fun trip down memory lane. Before TV and the internet, folks gathered around radios to get their news and entertainment. Following technological developments in sound amplification and transmission that occurred during World War I, the first commercial broadcasts began in the s, with radio quickly becoming the first major mass media outlet in the world, and revolutionizing the way that humans were able to consume new information. Just like what would become the internet of the future, not all could tell news from fiction; When a radio version of H. Bigger and shorter playing than the 33 RPM long-playing discs that would eventually replace them, these first records preserved the sounds of big band jazz, classical, and pop music of the day, often with just one or two songs per side.

Large Sound Amplification Systems in Interwar Germany: Siemens and Telefunken


In the s, electrical companies in Europe and North America started to develop large sound amplification systems for a variety of public spaces, such as public squares, town halls, theaters, cinemas, sports arenas, and churches. These large amplification systems differed in design to accommodate the various soundscapes, but they all required powerful radio tube amplifiers and large loudspeakers. In Germany, the Siemens and Halske company pioneered such systems in the s. The physicist Hans Riegger had worked for Siemens on underwater sound signaling systems for submarine communications, designing electrically driven sound transmitters—basically large underwater loudspeakers that transmitted sound signals of just one frequency into the ocean. Unlike underwater sound transmitters, which operated only at a single frequency, the Blatthaller and other loudspeakers needed to transmit the entire range of audible frequencies, and thus depended on amplifier tubes and circuits that could amplify the weak signals of microphones without too much distortion. During the war, Walther Schottky had worked for Siemens on screen grid vacuum tubes that enhanced the performance of the Siemens tubes considerably. From about onwards, Schottky and Erwin Gerlach set to work on a loudspeaker in which a current-carrying aluminum ribbon was suspended in the gap of a ring-shaped electromagnet.
