Device and method for integrating sound effect processing and active noise control
ActiveUS20070121956A1Reduce amountLow orderSound producing devicesLoudspeaker spatial/constructional arrangementsSignal-to-noise ratio (imaging)Loudspeaker
A device and a method for integrating 3D sound effect processing and active noise control are proposed. A digital signal processor incorporates an artificial reverberator and a 3D spatial audio processor into an audio module. The audio signal is presented via an earphone. Next, a microphone embedded in the vicinity of the loudspeaker inside the headset is used to sense an external noise while playing, and feed it back to an active noise controller, which generates an anti-noise to eliminate the external noise. Therefore, the signal to noise ratio can be increased and the 3D sound field effect can be significantly enhanced. In addition, a head-related transfer function is more efficiently implemented on the basis of an interaural transfer function in the spatial audio processing to reduce the filter order lower and hence the computation loading.

An infrared (IR) emitter having a broad emission pattern driven by a frequency-modulated (FM) carrier signal enables electronic communication between multiple talkers and multiple listeners. A narrow reception pattern on the listener's receiving unit combined with the inherent capture effect of FM coding provides each listener with the means of easily and naturally selecting one of many talkers from a group. A close microphone for the talking party and a close earphone for the listening party enables the system to assist conversation particularly in the case of noisy environments by improving the signal to noise ratio. A similar system of broad emission transmitters and narrow reception can be used in other systems, such as a teleconferencing unit in which users have transmitters and receivers and a teleconferencing unit has multiple receivers arranged to receive signals in multiple different sectors.
