A tapping machine is a device used to test the impact sound insulation of floors, for measurements of impact noise (noise of footsteps) in the field of

building acoustics Architectural acoustics (also known as building acoustics) is the science and engineering of achieving a good sound within a building and is a branch of acoustical engineering. The first application of modern scientific methods to architectur ...

. The standard tapping machineISO 16283-2:2015(E) Acoustics — Field measurement of sound insulation in buildings and of building elements — Part 2: Impact sound insulation has five hammers placed in a line. Each hammer is lifted and dropped in turn, creating 10 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 In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity (e.g. moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a p ...

and frequency of the impacts is known, the impact insulation provided by the floor can be determined from the sound level.
