Gallery 7:
How it all Works

The primary display here demonstrates a variety of radio sound effects. In the medium’s earliest days, any sounds had to be created by hand (such as network chimes, horses’ hooves, or an oncoming storm)—by the late 1930s, stations could purchase records with virtually any sound desired. Visitors can try their hand at many of these. Remember that over low-fidelity AM radio, the sounds would seem more realistic than they do to our ears today.

Younger visitors especially enjoy the display cabinet showing novelty radios designed to look like something else. A wall display shows the development of electronics from the days of vacuum tubes to today’s modern printed circuits. Another shows the use of different parts of the electromagnetic spectrum.
