Abstract: This paper presents experimental results from a demonstration of feedback control experiments on an open-ended acoustic duct, using nodally placed colocated actuator-sensor pairs. The disturbance signal used in the experiments is bandlimited and random. The first three modes undergo as much as 20 dB attenuation. The simplicity of the nodal control together with the spatially global sound reduction makes this a suitable technique for suppressing low frequency broadband duct noise.
