摘要： A system for evaluating a noise management module of a vehicle includes a controller programmed to filter speaker signals from the noise management module using an auralization model to produce auralized sound signals that create a spatial effect to simulate sound in the vehicle at a predetermined position within the vehicle that is different than the positions corresponding to microphones used by the noise management module.

摘要： An audio system includes a plurality of near-field speakers arranged in a listening area. A plurality of cross-talk cancellation filters are coupled to the speakers. The speakers and the filters are arranged to provide first and second listening zones in the listening area such that audio from the first listening zone is cancelled in the second listening zone and vice versa. Volume-based equalization circuitry receives an audio signal representing audio content for the first listening zone from an audio source and controls a volume adjustment applied to the audio signal to control a volume of audio in the first listening zone. The circuitry limits attenuation or amplification of a first frequency portion of the audio signal when a volume setting differential corresponding to a difference between volume settings for the first and second zones exceeds a predetermined value.

摘要： A crosstalk cancelation technique reduces feedback in a shared acoustic space by canceling out some or all parts of sound signals that would otherwise be produced by a loudspeaker to only be captured by a microphone that, recursively, would cause these sounds signals to be reproduced again on the loudspeaker as feedback. Crosstalk cancelation can be used in a multichannel acoustic system (MAS) comprising an arrangement of microphones, loudspeakers, and a processor to together enhance conversational speech between in a shared acoustic space. To achieve crosstalk cancelation, a processor analyzes the inputs of each microphone, compares it to the output of far loudspeaker(s) relative to each such microphone, and cancels out any portion of a sound signal received by the microphone that matches signals that were just produced by the far loudspeaker(s) and sending only the remaining sound signal (if any) to such far loudspeakers.
摘要翻译：串扰消除技术通过消除由扬声器产生的声音信号的一些或所有部分，仅由麦克风捕获，从而减少共享声学空间中的反馈，该麦克风递归地将使这些声音信号再次再现扬声器作为反馈。串扰消除可以用在包括麦克风，扬声器和处理器的布置的多声道声学系统（MAS）中，以一起增强共享声学空间之间的会话语音。为了实现串扰消除，处理器分析每个麦克风的输入，将其与相对于每个这样的麦克风的远扬声器的输出进行比较，并且取消与麦克风接收的声音信号匹配的信号的任何部分由远扬声器产生，并且仅向剩余的扬声器发送剩余的声音信号（如果有的话）。

摘要：　音量制御装置は、例えば車室などの音響空間に適用され、車室内の座席などに設定される聴取位置における再生音のレベルを制御する。具体的には、音量制御装置は、外部より入力された音声信号に対して位相差を与えて一対のスピーカに供給する。ここで、位相差は、聴取位置の前方のスピーカから再生される音声信号と聴取位置の後方のスピーカから再生される音声信号の、所定周波数より小さい周波数について算出される。また、その位相差は、聴取位置における再生音レベルが、一対のスピーカのうちの一方のスピーカのみで音声信号を再生したときの再生音レベルよりも小さくなるように算出される。

摘要： A system and method is described for determining whether a loudspeaker device has relocated, tilted, rotated, or changed environment such that one or more parameters for driving the loudspeaker may be modified and/or a complete reconfiguration of the loudspeaker system may be performed. In one embodiment, the system may include a set of sensors. The sensors provide readings that are analyzed to determine 1) whether the loudspeaker has moved since a previous analysis and/or 2) a distance of movement and/or a degree change in orientation of the loudspeaker since the previous analysis. Upon determining the level of movement is below a threshold value, the system adjusts previous parameters used to drive one or more of the loudspeakers. By adjusting previous parameters instead of performing a complete recalibration, the system provides a more efficient technique for ensuring that the loudspeakers continue to produce accurate sound for the listener.

摘要： A method to enable one or more active sound zones in a closed environment and in which individual sound sources are provided to individual persons located within each sound zone. The sound zones are created as 3D domains defined according to the aspects of "acoustically bright zone" and "acoustically dark zone", and with predefined threshold values related to a required "acoustical contrast" among the plurality of sound zones. Characteristics of the closed environment, this being e.g. a room or a car cabin, are analyzed and predefined via in situ measurement of the actual room/car cabin. A constraint based system controls the configuring of the individual sound zones according to relevant constraint parameters e.g., but not limited to: loudspeaker transducer configuration, number of sound channels, number and location of persons in the domain, room characteristics, (size, isolation, reflection, temperature), type of source material (speech, music genre, sound volume per zone).
