Abstract

Example embodiments disclosed herein relate to noise level estimation. A method for noise level estimation is disclosed. The method includes, responsive to an increase of a signal level of a noise signal, calculating an impulsive noise probability of the noise signal, the impulsive noise probability indicating a likelihood that the noise signal is an impulsive noise. The method also includes determining a variable smoothing factor for noise level estimation based on the impulsive noise probability, the variable smoothing factor being associated with a previous estimated level of the noise signal. The method further includes smoothing the noise signal with the variable smoothing factor so as to determine a current estimated level of the noise signal. Corresponding system and computer program products are also disclosed.
