Abstract: A vehicle headrest includes a passive directional acoustic device. The passive directional acoustic device includes an acoustic driver, a pipe acoustically coupled to the acoustic driver. The pipe includes an elongated opening along at least a portion of the length of the pipe through which acoustic energy is radiated to the environment. The radiation is characterized by a volume velocity. The pipe and the opening are configured so that the magnitude of the volume velocity is substantially constant along the length of the pipe.

Abstract: 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. The system also includes at least one audio source providing audio content. Volume-based equalization circuitry receives an audio signal representing audio content for the first listening zone from the 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.
Abstract translation: 音频系统包括布置在收听区域中的多个近场扬声器。 多个串扰消除滤波器耦合到扬声器。 扬声器和滤波器被布置成在收听区域中提供第一和第二聆听区域，使得来自第一聆听区域的音频在第二监听区域被取消，反之亦然。 该系统还包括提供音频内容的至少一个音频源。 基于音量的均衡电路从音频源接收表示用于第一聆听区域的音频内容的音频信号，并且控制应用于音频信号的音量调节，以控制第一聆听区域中的音频音量。 当对应于第一和第二区域的音量设置之间的差异的音量设定差异超过预定值时，电路限制音频信号的第一频率部分的衰减或放大。

Abstract: An audio enhancement method includes receiving a first plurality of input signals representative of audio captured using an array of two or more sensors, the first plurality of input signals characterized by a first signal-to-noise ratio (SNR), with the audio being the signal-of-interest. The method also includes receiving a second input signal representative of the audio, the second input signal characterized by a second SNR. The second SNR is higher than the first SNR. The method further includes combining the first plurality of input signals and the second input signal to generate one or more driver signals, and driving one or more acoustic transducers using the one or more driver signals to generate an acoustic signal representative of the audio. The driver signals include spatial information derived from the first plurality of input signals, and are characterized by a third SNR that is higher than the first SNR.

Abstract: A method is provided for directing a user to a point of interest using sounds played on a wearable audio output device. A user's direction of gaze is determined using data from at least one sensor in the audio output device. First and second locations are determined of the user and the point of interest respectively, and a distance is determined between the first and second locations. A relative angle between the direction of gaze and the direction of the point of interest is determined based on the determined first and second locations. A sample sound is altered using at least one sonification technique to convey information relating to the determined distance and the relative angle. The altered sample sound is rendered and output for playing by the audio output device.

Abstract: Aspects of the present disclosure provide methods, apparatuses, and systems for closed-loop respiration entrainment based on spatialized audio signals. According to an aspect, based on a determined rate of a subject's respiration, spatialization of a virtual sound source is altered to simulate a distance or directionality to the subject. Simulating the distance, directionality, and/or source characteristics comprises processing sounds of the virtual sound source to generate a perception of the sounds being heard from one or more distances or directions with reference to the subject. The altered virtual sound source attempts to regulate the rate of respiration of the subject. An audio device outputs the sounds of the altered virtual sound source.

Abstract: Various implementations include systems and approaches for binaural testing. In one implementation, a system includes a binaural test dummy including a body having: a head-and-neck region; and a set of head-mounted microphones coupled with the head-and-neck region at anatomically correct ear locations; and a control system coupled with the binaural test dummy for incrementally modifying a position of the binaural test dummy across a range of motion.
