20130163747 | MULTI-MICROPHONE SYSTEM TO SUPPORT BANDPASS FILTERING FOR ANALOG-TO-DIGITAL CONVERSIONS AT DIFFERENT DATA RATES - One exemplary problem addressed by the techniques disclosed herein is that the A-to-D converter of the broad-band audio codec that is being used more frequently in IP telephony, G.722, samples the analog audio source 16,000 times per second, rather than 8,000. Since all G.722-capable telephones must continue to be G.711-capable, one problem is that a microphone that provides appropriate bandpass filtering for G.722 encoding fails to provide adequate filtering for G.711. One exemplary aspect is therefore directed to telephones that must be able to switch back and forth between narrow-band digital audio encoding in which the A-to-D converter samples the audio stream 8,000 times per second, and a wide-band audio encoding in which the A-to-D converter samples the audio stream 16,000 times per second.

Specifically, time domain samples are read from the transmit (Tx) and receive (Rx) paths of the modem. These samples are stored in memory. When the sync frame has received a predetermined number of the same Tx samples and Rx samples, the samples are stored. Running averages, over the sync frames, of the TX and RX samples are maintained. These averages are subtracted from a sync frame of samples, to allow LMS updating of the echo canceller taps, free of extraneous signals. Updating, i.e., tracking of changes in the echo channel, is done for the echo canceller in an off-line fashion. The coefficients for the in-line version are updated, while the off-line version is updated over several sync frames. Periodically, the performance of the off-line version is compared with the in-line version. The coefficients of the in-line version are replaced by those of the off-line version only if it is determined the off-line version, which is tracking echo channel changes, has better performance. After replacement of the in-line coefficients, the off-line tracking is continued in the off-line version. | 2013-06-27 |

20130163772 | SOUND MASKING DEVICE AND SOUND MASKING METHOD - A sound masking device includes: a sound pick-up unit which picks up a sound, and which produces a picked-up sound signal based on the sound, a masking sound signal producing unit which produces a masking sound signal from the picked-up sound signal a sound emitting unit which emits a masking sound based on the masking sound signal, and an echo cancelling unit which performs an echo cancelling process on the picked-up sound signal by performing an adaptive filtering process on the masking sound signal, and by subtracting the filtered masking sound signal from the picked-up sound signal. The masking sound signal producing unit produces a masking sound signal having a level corresponding to an amplitude level of the picked-up sound signal which has subjected to the echo cancelling process. | 2013-06-27 |
20130163773 | CLOSED-LOOP ACTIVE NOISE REDUCTION SYSTEM, SUCH AS FOR A THERMAL PRINTER - A system and method for reduce noise emitted by a printer are disclosed herein. In one embodiment, a sound detector disposed proximate to a noise source detects a measured noise signal, which is analyzed to determine one or more resonant frequencies thereof. A feedback signal is determined based on the analyzed noise signal and is used to generate a compensated signal 180 degrees out of phase with the feedback signal. The compensated signal is output proximate to the noise source. | 2013-06-27 |
20130163774 | NOISE REDUCTION APPARATUS - The noise reduction apparatus according to the present disclosure includes a plurality of loudspeakers, control sound signal generating units, and a plurality of error microphones. Each of the control sound signal generating units generates control sound signal based on the error sound detected by a corresponding error microphone of the plurality of error microphones. The noise reduction apparatus further including an input switching unit that, when a level of the noise at a predetermined position is higher than the predetermined threshold value, feeds an error audio signal at a predetermined control point of the plurality of control points or a control point that is newly set based on the plurality of control points into each of the control sound signal generating units, the number of the newly set control point being less than the number of the plurality of control points | 2013-06-27 |
20130163775 | Communications Headset Speech-Based Gain Control - A gain of a signal representing sounds detected by a talk-through and/or feedforward ANR microphone of a talk-through function provided by a communications headset is reduced in response to a user of the communications headset speaking. | 2013-06-27 |
20130163776 | Headset Noise-Based Pulsed Attenuation - A headset having a talk-through microphones incorporates an audio circuit that compresses a signal representing sounds detected by the talk-through microphones in response to the audio circuit detecting the onset of a peak (positive and/or negative) in the signal that exceeds a predetermined voltage level (positive and/or negative voltage level, perhaps a predetermined magnitude of voltage from a zero voltage level), and that does so with a rate of change in voltage level that exceeds a predetermined rate of change in voltage level, the degree of compression possibly being a compression to or near a zero amplitude (perhaps to or near a zero voltage level) and the duration of the compression possibly being controlled by a timing circuit set to a predetermined period of time that may be retriggerable while amidst the predetermined period of time. | 2013-06-27 |
