Modifying a massless scalar field's interaction with a dynamical black hole background via the smearing operator $e^{\\ell^2\\Box}$ (where $\\ell$ denotes the string length scale), we calculate the time-dependent number expectation value $\\langle \\hat{N}(u) \\rangle$ of outgoing Hawking particles at retarded time $u$.
