Acoustics Teaching Instruments

This acoustical instrument, the sound analyser, made sound waves visible. It allowed one to "see" the simple tones that contributed to the rich, complex sound of an organ pipe, or violin. A musical note was played or sung before the brass receptacles (resonators) and the sound waves were transformed into distinct and separate flame patterns.

Before 1860, physicists only studied sound with a well-practiced ear. Rudolf Koenig of Paris invented several novel ways to study sound waves with the eye. Visualizing sound was particularly attractive for classroom demonstrations and enabled students to conceptualize sound in new ways.
