Geoff Manaugh talked to sonic historian Sabine von Fischer about clairadient buildings, The Rumbler, nightingale floors and the tapping machine:

What was the tapping machine?

SVF: The tapping machine, as it was first published in 1930 and as it was standardized in the 1960s, has five steel rods that hammer against the floor. The speed has changed a bit over time – and its speed is now standardized – but it just tramples on the floor. It's a very basic machine.

The principle of the machine can be found in older apparatuses, such as those used in grinding food items, but this particular application was to simulate the sound of footsteps, furniture, and machines on the floors of multistorey buildings. In this form – with five hammers, which are electrically operated – it was first published in 1930, in the Journal of the Acoustical Society of America.

Everyone who has been working on building acoustics claims that, since 1923 or 1926, they've been doing similar tests on structure-borne sound, but almost all of those earlier tests were done with women in high-heeled shoes. High-heeled shoes make a very distinct sound. For impact-sound measurements, these women – and I have never seen a photo with a man or a documentation of a test done with a man – would wear high-heeled shoes, making a very standard noise.
