摘要： An acoustic conduit provides a waveguide for coupling a loudspeaker inside a vehicle to a region outside the vehicle, or vice versa. The acoustic conduit includes a proximal opening configured to accommodate the loudspeaker. A distal opening is configured to acoustically couple to an exterior of the vehicle. The acoustic conduit defines an interior volume between the proximal opening and the distal opening and is configured to provide waveguide acoustic coupling between the loudspeaker and the exterior.

摘要： A method to produce a dynamic sound stage for engine harmonic enhancement (EHE). Dynamic refers to the ability to position the sound stage at different positions as the engine operates at various RPMs and load. In order to control the sound stage width, a phase difference can be introduced between a first audio channel (e.g., a left audio channel) and second audio channel (e.g., a right audio channel). In the most general case, the phase difference can be introduced per harmonic per RPM. In this approach, the phase difference can be adjusted such that a vehicle occupant will perceive each harmonic signal to have a particular width. This width can be adjusted independently per RPM regions by tuning the per harmonic phase difference.
摘要翻译：一种用于产生发动机谐波增强（EHE）的动态声级的方法。动态是指当发动机以各种RPM和负载运行时将声级定位在不同位置的能力。为了控制声级宽度，可以在第一音频通道（例如，左音频通道）和第二音频通道（例如，右音频通道）之间引入相位差。在最普遍的情况下，可以每RPM谐波引入相位差。在这种方法中，可以调节相位差，使得车辆乘员将感知每个谐波信号具有特定的宽度。通过调整每个谐波相位差，可以每个RPM区域独立地调整此宽度。

摘要： Audio systems, methods, and computer readable mediums having program code to receive a harmonic signal related to rotating equipment, such as a vehicle drivetrain in some examples, and provide a harmonic cancellation (or enhancement) signal. The harmonic cancellation signal is transduced into an acoustic signal, and a feedback sensor, such as a microphone, detects an error signal representative of acoustic energy at a first location in the environment. A projection filter filters the error signal to provide an estimated error signal at a second location in the environment, such as at the location of an occupant's ear(s). An adaptive module adjusts the cancellation signal based on the estimated error signal.
