Ingard, Notes on Acoustics ( Infinity Science Press, Hingham, MA, 2008). but we can think that when the size of the panels is small compared to the wavelength, it is the resistive effect which predominates and that if vibrations are involved, it is in the form of resonances which are localized in frequency. That is the subject of this paper.
