I'm a software programmer (not a physics expert) trying out a smartphone vibration detection algorithm on desks, and I want to measure the impact of the desk's material features on the algorithm. Are there canonical measurements for desk density, rigidity, etc. that will affect vibrations? Intuitively, I'm guessing a metal desktop surface will transmit vibrations more than a wood one.
If there is some measurement device, like a stud finder, that would be great.
