Piezo drum pad - what materials should I house the sensor in?

Hi all, I'm trying to check around to see exactly what materials people have used to create their own DIY drum pad projects.
I am using a ceramic piezo sensor and the entire disc is about 1" diameter. I will attach a product link if that helps, just let me know.

The things I keep reading over and over again are foam, rubber, and a metal disc and basically those get sandwiched together with the foam on bottom as a vibration dampener I assume, then the metal disc on top of that with the piezo glued or otherwise attached onto the metal disc.

It seems like there are multiple ways to do this and this is my first DIY project.
Please please give me your suggestions because I really want to complete this project, learn from it and then make it better and focus on velocity sensitivity in the next run.
Thank you for your time and for reading!
