Oh okay. Sorry lmao

High frequency doesn't really travel better than low frequency. It's just that low frequency (from the same source) spreads out more. Nonuniform absorbing stuff is due to resonance, & overall amplitude losses in those freqs is because the material has friction inside and heats up.

My go-to resonance example is that toy with all the pendula on it, picrel. You can vary the length or weight of the strings, to demonstrate different "stiffness" . Pendulum Snake. Build your own for $8
