  5.3              Controlling      Background         Creep
  To the extent that it is reasonable to do so. noise from an activity must not be-


         •     for noise that is continuous      noise measured by LA9Q.T-more than nil dB(A) greater than the

              existing acoustic environment            measured by LA90.T;or


         •     for noise that varies over time measured by LAeq.adj.T-more than 5dB(A) greater than the

               existing acoustic environment           measured by LA9Q,T
