    Abstract

    This paper presents various experimental results of a real-time, multiple-channel, broadband Active Noise Control (ANC) system, employing the Remote Microphone Technique (RMT) as virtual sensing algorithm in different settings. The effects of virtual sensing on the shape and size of the quiet zone are experimentally investigated. To enhance the quiet zone, an acoustic energy density probe can be used as error sensor. Such a sensor not only measures sound pressure, but also the particle velocity in three directions, providing four signals to be minimized by the ANC system. The RMT is used to construct a virtual three dimensional, acoustic energy density probe, which is validated in real-time ANC. In conclusion, advantages, drawbacks and practical considerations of using RMT virtual sensing in active noise control are discussed.
