We study the intermittency and noise of dislocation systems undergoing shear deformation. Simulations of a simple two-dimensional discrete dislocation dynamics model indicate that the deformation rate exhibits a power spectrum scaling of the type $1โˆ•{f}^{\ensuremath{\alpha}}$. The noise exponent is far away from a Lorentzian, with $\ensuremath{\alpha}\ensuremath{\approx}1.5$. This result is directly โ€ฆ
