This part of ISO 16283 specifies procedures to determine the impact sound insulation using soundpressure measurements with an impact source operating on a floor or stairs in a building. Theseprocedures are intended for room volumes in the range from 10 m3 to 250 m3 in the frequency rangefrom 50 Hz to 5 000 Hz. The test results can be used to quantify, assess and compare the impact soundinsulation in unfurnished or furnished rooms where the sound field might, or might not approximate toa diffuse field.Two impact sources are described: the tapping machine and the rubber ball. These impact sources donot exactly replicate all possible types of real impacts on floors or stairs in buildings.The tapping machine can be used to assess a variety of light, hard impacts such as footsteps fromwalkers wearing hard‐heeled footwear or dropped objects. A single number quantity can be calculatedusing the rating procedures in ISO 717‐2. This single number quantity links the measured impact soundinsulation using the tapping machine to subjective assessment of general impacts in dwellings thatoccur on floors or stairs in a building. The tapping machine is also well‐suited to the prediction ofimpact sound insulation using ISO 15712‐2. These two aspects facilitate the specification of impactsound insulation in national building requirements using only measurements with the tapping machineas an impact source.The rubber ball can be used to assess heavy, soft impacts such as from walkers in bare feet or childrenjumping, as well as quantifying absolute values that can be related to human disturbance in terms of aFast time‐weighted maximum sound pressure level. At present, calculation procedures for a singlenumber quantity do not currently exist in an ISO Standard.
