    what is z, p, and c
  4. Feb 2, 2010 #3
    acoustic impedance z
    density p
    speed of sound c

    the speed of sound is 330 ms-1
    density is 1.3 kg m-3
    i need to know what to do with density and spped of sound to get acoustic impendance i know the answer is 0.00043 kg m -2 s-1 x10 but i do not know how to work out the formula?

    z=pc means z=p times c.
