A Review of Virtual Sensing Algorithms for Active Noise Control
Traditional local active noise control systems minimise the measured acoustic pressure to generate a zone of quiet at the physical error sensor location. The resulting zone of quiet is generally limited in size and this requires the physical error sensor be placed at the desired location of attenuation, which is often inconvenient. To overcome this, a number of virtual sensing algorithms have b...
متن کاملReview of active noise control algorithms for impulsive noise control
Active noise control is gaining popularity in recent years. Especially, active control of impulsive noise is of great interest. Due to specific nature of such noise, standard approach to active control is not satisfying. This paper reviews existing algorithms specifically developed for impulsive noise control. Performance of the algorithms is verified using computer simulations and several nois...
متن کاملActive noise control at a moving virtual microphone using the SOTDF moving virtual sensing method
Traditional local active noise control systems minimise the measured acoustic sound pressure to generate a zone of quiet at a physical error sensor. The resulting zone of quiet is generally limited in size and as such, placement of a physical error sensor at the location of desired attenuation is required, which is often inconvenient. Virtual acoustic sensors can be used to project the zone of ...
متن کاملOptimal virtual sensing for active noise control in a rigid-walled acoustic duct
The performance of local active noise control systems is generally limited by the small sizes of the zones of quiet created at the error sensors. This is often exacerbated by the fact that the error sensors can not always be located close to an observer’s ears. Virtual sensing is a method which can move the zone of quiet away from the physical location of the transducers to a desired location, ...
