  The reduction of quantum scattering leads to the suppression of shot noise.
In the present paper, we analyze the crossover from the quantum transport
regime with universal shot noise, to the classical regime where noise vanishes.
By making use of the stochastic path integral approach, we find the statistics
of transport and the transmission properties of a chaotic cavity as a function
of a system parameter controlling the crossover. We identify three different
scenarios of the crossover.
