Abstract: One of the instruments created in the late 1920s, in an endeavor to resolve the problem of inherent subjectivity in sound assessment, was the “machine for producing impact sounds.” Later it became known as the “tapping machine,” or “Hammerwerk” in German, or “machine à chocs” in French: a stunningly simple mechanism that hammered on floors to test their acoustic qualities as well as the level of sound insulation provided by various construction types. This hammering apparatus appears at first glance to bring architecture and machine into a straightforward sonic relationship. However, the human hearing threshold, until around 1930 was part of the test too, and this entangled architecture and machine in a more complicated relationship, one of mediatized sensation. Automation of the tests relieved the acoustic sciences of this tension. Yet still, the differences between measuring sound with an apparatus and assessing sound by hearing left ample room for debate.
