Is there a general level of vibration that describes most solid state matter that we can touch? Perhaps in hertz?

This is important in the theory of specific heat capacity of solids at low temperatures. Einstein had a go but got it wrong. Debye did a better job. Later work showed there was no unique frequency but a spectrum of frequencies. Later still quantum mechanics was applied and we got phonons (the vibrational equivalent of the photon). Look up Debye and specific heat capacity in a search engine for details
