摘要： A method for adjusting an audio zone sound image in an audio system (2, 6, 7) comprising a plurality of audio zones (2A, 2B, 6A, 6B, 6C, 6D, 7A, 7B, 7C) is disclosed. Each audio zone has one or more loudspeakers (20, 21, 60, 61, 63, 64, 65, 66, 67, 68, 69, 70, 72, 73, 74, 75) located therein. The method comprises recording (101, 802) a sound image of a controlling audio zone; transmitting (102, 803) audio data corresponding to the recorded sound image to a controller; evaluating (103, 103a, 804) the transmitted audio data; selecting (104, 805) an adjusting audio zone, wherein the adjusting audio zone is other than the controlling audio zone; and adjusting (105, 105a, 105b, 807) an adjusting loudspeaker such that the sound image of the controlling audio zone is changed. An audio system (2, 6, 7) and a controlling loudspeaker are also disclosed.

摘要： The amount of far-field noise transmitted by a primary communication device in an open-plan office environment is reduced by defining an acoustic perimeter of reference microphones around the primary device. Reference microphones generate a reference audio input including far-field noise in the proximity of the primary device. The primary device generates a main audio input including the voice of the primary speaker as well as background noise. Reference audio input is compared to main audio input to identify the background noise portion of the main audio signal. A noise reduction algorithm suppresses the identified background noise in the main audio signal. The one or more reference microphones defining the acoustic perimeter may be included in separate microphone devices placed in proximity to the main desktop phone, microphones within other nearby desktop telephone devices, or a combination of both types of devices.

摘要： There is provided a method of operating a device to generate a target sound that is audible to a user of the device, the method comprising measuring the background noise in the environment in which the device is located; using a perceptual loudness model to predict the audibility of the target sound to a user of the device based on the measured background noise; using the output of the perceptual loudness model to determine a gain value that is to be applied to a source signal used to generate the target sound in order to provide at least a desired level of audibility of the target sound to the user; applying the determined gain value to the source signal to produce a modified source signal; and generating the target sound using the modified source signal.

摘要： The various embodiments relate generally to systems, devices, apparatuses, and methods for providing audio streams to multiple listeners, and more specifically, to a system, a device, and a method for providing independent listener-specific audio streams to multiple listeners using a common audio source, such as a set of loudspeakers, and, optionally, a shared audio stream. In some embodiments, a method includes identifying a first audio stream for reception at a first region to be canceled at a second region, and generating a cancellation signal that is projected in another audio stream destined for the second region. The cancellation signal and the first audio steam are combined at the second region. Further, a compensation signal to reduce the cancellation signal at the first region can be generated.

摘要： A system of this invention is directed to a speech processing system that efficiently performs noise suppression processing for a plurality of noise sources spreading in a lateral direction with respect to a speaker of interest. The speech processing system includes a microphone array including a plurality of microphones, each of which inputs a sound mixture including speech of a speaker of interest and noise from a noise source region including a plurality of noise sources placed in a lateral direction with respect to the speaker of interest, and outputs a mixture signal including a speech signal and a noise signal, the plurality of microphones being arranged such that a difference between respective distances from the plurality of microphones to the speaker of interest becomes different from a difference between respective distances from the plurality of microphones to the noise source region, and a noise suppressor that suppresses the noise based on the mixture signals output from the plurality of microphones.

摘要： In embodiments of this invention howling sounds are removed without disturbing speech and music. Microphone signals are converted to the frequency domain where howling frequencies are detected and estimated using howling to noise ratios. A notch filter adaptively designed for the howling frequency is applied to remove the howling.
