计算了具有小弹性电子平均自由程的金属接触中的散粒噪声。在没有非弹性散射的情况下，其值比具有相同电阻的隧道结小三倍。如果在大电压下接触足够长，则非平衡电子发射声子会导致电压的非线性噪声依赖性。
The shot noise in metal contacts with small elastic electron mean free path is calculated. In the absence of inelastic scattering its value is three times smaller than that of a tunnel junction with equal resistance. If the contact is sufficiently long at large voltages the emission of phonons by nonequilibrium electrons leads to a nonlinear noise dependence on voltage.
