No, the particles of the medium do not move forward themselves during the propagation of sound. Instead, they oscillate back and forth about their equilibrium positions, transferring energy to neighboring particles.

The disturbance caused by a source of sound propagates through the medium by setting neighboring particles into motion, leading to a chain reaction where each particle affects the one next to it.

When a source of sound creates a disturbance in a medium, it sets neighboring particles into motion, which in turn disturbs adjacent particles.

When an object vibrates, it displaces particles of the medium from their equilibrium positions, causing them to oscillate. These oscillating particles then transmit the sound energy by exerting forces on adjacent particles.

Sound moves through a medium as waves, with the vibrating object causing particles of the medium to oscillate, transmitting the sound energy from the source to the listener.
