Please explain as clear as possible im having trouble understanding the terms How are the acoustic variables related to sound waves? What are the terms used for areas of high pressure_________and low pressure__________ (I know pressure is measure in Pa pascals and is measuring how much force is focussed in an area. )

This is a slide that was provided

A measure of how much fone is focused in an area Density Typical units are bog/m'. ka/cm', Erml Symbol is D or g A measure of how much mass posts in a volume Distance between parts of Typical units are cm, m, but the medium] could also be feet and other Unity Symbols include D, X 1
