April, 2008 the way to calculate impact sound reduction level was changed from an LL-scale to an ΔL-scale.
The reason for this is that the old LL test didn't just measure the level of the soundproofing material but also depended a lot on how the structure the test was conducted in was formed.
The appropriate test for this product is JIS A 1440-1 for ΔLL products where the second L stands for Light.
