sound and other mechanical vibrations are quantized as bosonic particles called phonons.

The temperature dependence of resistivity (or its reciprocal, conductivity) can only be truly understood with quantum mechanics. In the same way that matter is an assembly of microscopic particles called atoms and a beam of light is a stream of microscopic particles called photons, thermal vibrations in a solid are a swarm of microscopic particles called phonons. The electrons are trying to drift toward the positive terminal of the battery, but the phonons keep crashing into them. The random direction of these collisions disturbs the attempted organized motion of the electrons against the electric field. The deflection or scattering of electrons with phonons is one source of resistance. As temperature rises, the number of phonons increases and with it the likelihood that the electrons and phonons will collide. Thus when temperature goes up, resistance goes up, and conductivity goes down

Sound is, at its basic level, the motion of moving particles. In the quantum mechanical picture, energy of vibration of atoms or molecules is described as phonons. Phonons are a quanta (packet) of energy that can be treated as a particle (matter).

At the full level, it is mechanical or material waves that is an oscillation of pressure.

In others words, yes and no.

Optical phonons are phonon polarization modes with a minimum frequency, regardless of wavelength, which occur in crystals with more than one atom per primitive cell.

Primitive cell is the early technological development....
