Sound energy density or sound density is the sound energy per
unit volume (according to Wikipedia).

The intensity of a sound is determined by the rate and density
of energy transfer. The larger the amplitude, the greater the
intensity, and the louder the sound.

Sound travels spherically from where it was made. If energy is
to be conserved a sphere of an earlier point will have a higher
flux density than one from a later point.

the intensity of a sound wave is a combination of its rate and
density of energy transfer.To change the intensity of sound we have
to make the amplitude higher or make it lower.
