 Compression is a region of the medium in which particles come closer i.e. , the distance between the particles becomes less than the normal distance between them. Thus there is a temporary decrease in volume and a consequent increase in the density of the medium. 
Similarly, in rarefaction, particle gets farther apart and a consequent decrease in density.
