In context|of a speed|aeronautics|lang=en terms the difference between plasmasonic and hypersonic

is that plasmasonic is (of a speed|aeronautics) far enough above the speed of sound as to cause ionization of the air through shock heating deriving from the sonic shockwave, with resultant radio blackout, and plasma sheath surrounding the object travelling at speed while hypersonic is (of a speed|aeronautics) far enough above the speed of sound as to cause significant differences in behaviour due to chemical reactions or disassociation of the air.
