  We theoretically study charge noise generated by excited neutral modes, which
impinge on the quantum point contact of a quantum Hall bar with filling
fraction v=2/3. The noise is computed for thermally excited neutral modes as
well as for biased neutral modes with dipole-fermion excitations. Within the
dipole-fermion picture, we show that the noise arising from two colliding modes
can be suppressed due to Pauli-blocking and be non-universal due to random edge
disorder, but becomes universal upon disorder-averaging. The ratio of noise due
to two colliding neutral modes and noise due to only one such mode is smaller
for dipole-fermions than for thermal excitations, thus providing evidence for
the different quantum statistics of the two types of excitations.
