Abstract
The study of the resonances of the Helmholtz resonator has been broadly described in previous works. Here, for a simple two dimensional resonator in the shape of a tube, we analyze the transition zone where oscillations start to appear. Following a careful analysis, we obtain an optimal lower bound of the width of the resonances.File in questo prodotto:
