The current procedure for rating the impact sound insulation of a floor is a two-step process. First, the spectrum of noise transmitted through a floor from a standard tapping machine is measured. Secondly, the spectrum of transmitted machine noise is compared with a standard arbitrary reference spectrum; thus, a single figure of merit for the impact sound insulation of the floor is determined. For a floor to have satisfactory impact sound insulation, the general consensus is that its Impact Noise Rating should be zero or positive.
