- ItemStanovení rezonance nanovlákenné vrstvy v závislosti na jejích parametrech(Technická Univerzita v Liberci, 2007) Hejgrlíková, Zuzana; Kalinová, KláraThis diploma thesis deals with the sound absorption characteristics of nanofibres layer. The first part of this paper contains summary of theoretical knowledges of the principles of sound absorption by different materials in connection with their structure. The second part is devoted to the measurement of sound absorption coefficient in dependence on changing frequency for different sound absorption system containing nanofibres layer with an air-back cavity. On the basis of these measurements, influence of different parameters on measured quantity is evaluated.
