    • 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.
    • 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。 基于音量的均衡电路从音频源接收表示用于第一监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整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。

    • A sound system design/simulation system includes background noise to provide more realistic sound renderings of the designed space and more accurate quality measures of the design space. The background noise may be provided as a library in the design system that allows the user to select a background noise profile. The user may also provide a recording of a background noise from the built space or from a similar space. The design system converts the recorded background noise to a background noise profile and adds the profile to the library of background noise profiles. The user can select a background noise profile and associate the profile with a specified space. The user can adjust the noise level of the background noise and the design system automatically updates one or more quality measures in response to the change in background noise level.
    • 音响系统设计/仿真系统包括背景噪音,可以为设计空间提供更逼真的声音效果,并提供更准确的设计空间质量测量。 背景噪声可以作为设计系统中的库来提供,其允许用户选择背景噪声分布。 用户还可以从建立的空间或类似的空间提供背景噪声的记录。 设计系统将记录的背景噪声转换为背景噪声分布,并将该轮廓添加到背景噪声分布图库中。 用户可以选择背景噪声分布,并将轮廓与指定的空间相关联。 用户可以调整背景噪声的噪声水平,并且设计系统响应于背景噪声水平的变化自动更新一个或多个质量测量。
