“Delta IIC is the best rating to consider when comparing the impact sound performance of different materials as it doesn’t allow for misleading results…” – ARC Acoustics

“The Delta IIC rating is the best sound rating to consider when comparing the performance of different types of underlayment. It keeps the manufacturers from promoting misleading results obtained by using materials or methods of isolation that the average assembly does not use.” ISO Store
