A tapping machine is a device used to test the impact sound insulation of floors,
for measurements of impact noise in the field of building
acoustics.
The standard tapping machine has five hammers placed in a line. Each hammer
is lifted and dropped in turn, creating 20 impacts per second on the floor.
In the room below or adjacent, a sound level meter is used to measure the sound
level created by the impacts. Because the force and frequency of the impacts is
known, the impact insulation provided by the floor can be determined from the
sound level.
