Abstract: A privacy apparatus adds a privacy sound based on a speaker's own voice into the environment, thereby confusing listeners as to which of the sounds is the real source. This permits disruption of the ability to understand the source speech of the user by eliminating segregation cues that the auditory system uses to interpret speech. The privacy apparatus minimizes segregation cues. The privacy apparatus is relatively quiet and thus easily acceptable in a typical open floor design office space. The privacy apparatus contains an A/D converter that converts the speech into a digital signal, a DSP that converts the digital signal into a privacy signal with pre-recorded speech fragments of the person speaking, a D/A converter that converts the privacy signal into an output signal and one or more loudspeakers from which the output signal is emitted.

Abstract: A system and method of masking an objectionable artifact in a mobile telephone. The process starts by referring to the design characteristics of the mobile phone to determine the expected level and source of objectionable artifacts that will be apparent during operation of the mobile phone. The noise necessary to mask the objectionable artifact is then calculated. The masking noise signal is then created within the mobile telephone and superimposed over the objectionable artifact. The masking noise signal is typically created in a digital signal processor (DSP) resident within the mobile telephone using a pseudo-noise generator. The masking noise signal can be stored as a look-up table in the digital signal processor (DSP) of the mobile telephone. To further enhance the effectiveness of the masking process, the masking noise signal is filtered to best match the objectionable artifact.
