- ItemVývoj optické metody stanovení rezonanční frekvence membrány(Technická Univerzita v Liberci, 2008) Kroulová, Jiřina; Kalinová, KláraThis thesis deals with the developement of optical method for membrane resonant frequency determination. The first part of this paper contains summary of theoretical knowledge of sound and its absorption with emphasis on constructions based on resonant frequency principle. The second part is concerned with the description of the developed method and testing device and experiment. On the basis of the measurements, influence of different area density on resonant frequency is evaluated.
