Finn jacobsen, department of electrical engineering, technical university of denmark (dtu) currently an associate professor in the department of electrical engineering at dtu, dr jacobsen has more than twenty-five years' experience of teaching acoustics at msc level, and more than 15 years' experience of teaching. When sound propagates through a medium, it results in pressure fluctuations that change the instantaneous density of the medium under such circumstances, the refractive index that characterizes the propagation of light is not constant, but influenced by the acoustic field this kind of interaction is known as the.

This paper is concerned with experimental validation of a recently proposed method of controlling sound fields with a circular double-layer array of loudspeakers [chang and jacobsen, j acoust soc am 131(6), 4518–4525 ( 2012)] the double-layer of loudspeakers is realized with 20 pairs of closed-box loudspeakers. Abstract this thesis contains three papers investigating problems of interest for noise control in ducts the first part of this thesis treats the sound propagation in rectangular ducts with flexible walls various experimental techniques are performed to measure the internal sound propagation and radiation to the surrounding.
