    摘要： The invention refers to a device for sound control in a space (2) with a sound field from at least one sound source (3). The device includes a pulse sensor (5), which provides a pulse signal from the sound source (3). Moreover, the device includes a number of sound influencing members (8) for reducing the sound field in the space (2) and a number of sound sensors (9), which sense the actual sound field in the space and provide an error signal. A control unit includes a signal supplied device (11, 12), which receives a pulse signal and supplies a first signal to an adaptive filter (15). The filter has a number of filter coefficients and generates a drive signal for each sound influencing member (8). The signals supply device also supplies second signals to a calculating member (24), which calculates the value of the filter coefficients by the second signals and the error signals for updating the adaptive filter (15). A detecting member detects phase and frequency of the pulse signal and a coefficient table provides two sets of coefficients for generating the second signals from detected phase and frequency of the pulse signal.

    摘要： An active buffeting noise control arrangement for a vehicle having one or more window panels of a vehicle cabin. One or more actuators are positioned at or near the one or more window panels and are operable to selectively vibrate the one or more windows in order to generate sound waves that will counteract a low frequency throb or buffeting event. The arrangement further includes one or more sensors in a vehicle cabin for detecting the buffeting event in transmitting sensor data to a control module. The control module is connected to the one or more sensors as well as the one or more actuators where the control module receives the sensory data, determines if a buffeting event is occurring and commands the one or more actuator assemblies to vibrate the window and generate sound waves that are operable to counteract the buffeting event.
