摘要： Aspects of the present invention relate to active vibration control apparatus (1) for a vehicle (2). The active vibration control apparatus (1) comprises a controller (7) including an electronic processor (10) having an electrical output for outputting a vibration control signal (SIG) to control operation of an actuator (8). An electronic memory device (11) is electrically coupled to the at least one electronic processor (10) and has a set of instructions stored therein. The at least one electronic processor (10) is configured to access the memory device (11) and execute the instructions stored therein such that it is operable to generate the vibration control signal (SIG). The vibration control signal (SIG) is generated by combining a vibration-reducing signal (SIG V ) for controlling actuation of the actuator (8) to reduce one or more first vibration component, and a sound-generating signal (SIG S ) for controlling actuation of the actuator (8) to increase one or more second vibration component.

摘要： A system and method for reducing noise from an internal combustion engine using a duct housing (10) receiving induction air flow to the engine. A space is defined within the duct housing (10) surrounding a speaker enclosure (22) associated with a speaker (30) facing an open space upstream of the annular space. A sound transducer (42) at the axial location where the annular space opens into the open space generates electrical signals corresponding to engine noise propagating through the air induction ducting. The signals are amplified and phase shifted driving the speaker to output cancelling noises or sounds so as to at least reduce engine noise from the annular space. The speaker enclosure length is set to enhance speaker performance in selected frequency bands of engine noise.

摘要： A method and system for a noise cancellation comprises an amplifier in communication with the three or more speakers disposed in an area. A system controller produces a driver signal for each of the speakers in response to a signal from at least one microphone detecting sound in the area and communicates the driver signals to the amplifier. The amplifier drives each speaker with the driver signal produced for that speaker. In response to the driver signals, the speakers emit sound that combined produces a substantially uniform sound pressure field for a particular zone within the area. The substantially uniform sound pressure field produced by the speakers has a magnitude and phase adapted to attenuate a noise field in the area corresponding to the sound detected by the at least one microphone.

摘要： A system, device and method that is configured to operate an active noise reduction system for a motor vehicle, where there is an adaptive feed-forward noise reduction system input sine wave at a frequency to be cancelled, and where the adaptive feed-forward noise reduction system includes an adaptive filter that outputs noise reduction signals that are used to drive one or more transducers with their outputs directed to reduce engine noise, and further includes an input transducer with an output signal that is a source of a control signal for the adaptive filter. The output signal of the input transducer is filtered before it reaches the adaptive filter so as to reduce the level of the output signal of the input transducer at one or more frequencies that are close to the frequency of the input sine wave.

摘要： A noise suppressor, and associated method, suppresses periodic noise components of a communication signal. The period of the periodic noise components of the communication signal is determined by correlating the communication signal with the communication signal, delayed by various delay amounts. Once the period of the noise component portion is determined, a periodic signal exhibiting a corresponding periodicity is generated and subtracted from the communication signal. The resultant difference signal forms a noise-suppressed communication signal. When embodied in a radiotelephonic device, background noise formed of an engine sound caused by the running engine of a motor vehicle at which the radiotelephonic device is operated can be suppressed during operation of the noise suppressor.

摘要： A method of reducing the adaption time needed to adapt a synthetically generated secondary waveform so that it nulls a primary repetitive waveform (e.g. noise) from a source (1) of vibration, the secondary waveform generation (5) being synchronised by the source (1). The polarity and/or the amplitude of at least a part of the signal resulting from interaction between the primary and secondary waveforms is sensed (6) and used (7, 8) to reshape the secondary waveform. The invention finds application in the cancelling of repetitive vibrations (e.g. in quietening the driving cab of a vehicle).
