Abstract: A device and method generate a sound masker to mask sound of the ambient environment. More specifically, spectral characteristics of sound in the ambient environment are determined, where the spectral characteristics are determined in terms of auditory excitation patterns. A database of pre-recorded sounds is searched to identify at least one pre-recorded sound that has spectral characteristics corresponding to the spectral characteristics of the sound in the ambient environment. At least a portion of the identified at least one pre-recorded sound is reproduced to mask the sound in the ambient environment.
