- RION Impact Ball YI-01
Measures floor impact sound insulation properties of building materials
YI-01 conforms the rubber ball impact source defined in ISO 10140-3: 2010 and JIS A 148-2: 2019.
This is used when the impact force of a standard impact source (bang machine) with impact force properties (1) is excessive for a building with a lightweight structure.
Easy to carry, weighing just 2.5 kg. A consistent impact force is achieved by free-dropping from a height of 1 m.
