The control system 116 is operable to generate the actuator driving signal to cause the first measurement and second measurement to conform to a target relationship. The control system 116 may comprise an input stage for inputting of first and second signals indicative of an acceleration of the structure 102 and a force exerted between the structure 102 and the vibration absorber 100 respectively; a digital adaptive filter for outputting a control signal for driving the actuator 110; first and second processing units for processing the acceleration and force signals via comparison with desired acceleration and force signals to generate an error signal; and a third processing unit for adapting the adaptive filter to minimize the error signal.

Abstract: To reduce noise inside a motor car passenger compartment, two loudspeakers (371, 372) are driven by signals derived from a reference signal x(n) by adaptive filtering carried out by a programmed microprocessor and memory unit (36) which adapts the filtering in dependence on error signals el(n) from four microphones (421, 422, 423 and 424) distributed in the passenger compartment. Reference filtering coefficients are initially determined by analysis of finite impulse responses when white noise is acoustically coupled from the loudspeakers (37) to the microphones (42), a white noise generator (48) being coupled to the unit (36). The reference signal x(n) is restricted to one or more selected harmonics or subharmonics of the fundamental noise frequency by a filter (34) which tracks the selected frequency. The selected frequency may be obtained from a coil (31) in the ignition circuit of the vehicle.

Abstract: Each of a plurality of acoustic sensors (acoustically coupled to a structure for monitoring) is connected to a network bus system via a preamplifier for capturing, processing and reporting acoustic events in a structure, for example aircraft structures. Each of the preamplifiers processes the acoustic event signals received from the sensors when an acoustic emission resulting from an acoustic event (defect in a structure, impact on the structure etc), and passes digital processed signal data relating to the detected acoustic event to a Remote Data Concentrator over the network for collation. The collated data is then stored and/or further processed (at a later time or in near real-time) to determine the source and/or location of detected acoustic emissions in the structure.
