Perlin noise amplitude/frequency

Hello! I’m trying to add ripples on Voronoi cells using Perlin noise, and I want them to have an amplitude of 5% and frequency of 10% of the Voronoi cell size. There’s already a spacing of 10% cell size in between them. How can I proceed to achieve this? Below is a sketch of what I would like to achieve and I’ve attached the Grasshopper script too.

Thanks a lot in advance!
