This kind of panel is made from porous materials. This way the particles that transport the sound enter the material through the pores and are imprisoned as such inside the material, thus effectively interrupting the acoustic wave's path.

In the previous paragraph we saw how the flow of atmospheric pressure in relation to the active loudspeaker can be visualized as a waveform. Waveforms can actually be very complicated, but fortunately every single one of them, and I mean every single one, can be considered as an extension of a very simple wave form: the sinusoid
