    No relationship. Intensity can be any value so is the pressure. Pressure and intensity are not related.

    I = watt/m^2

    p = N/m^2

    since watt are N*m/sec , then I/p = m/sec , i.e. a speed

    The ENERGY stored in something that is compressed, like a spring, is proportional to the square of the compression.

    ( E =1/2 k x^2 = 1/2 k (yP)^2)

    so that the intensity ( meaning the energy in the wave ) is proportional to the square of the physical amplitude.

    Which in turn is a measure of the pressure.

    so i is proportional to P^2
