Determination of the Material Acoustic Impedance
Vozárová, Juliana ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This diploma thesis deals with the determination of the material acoustic absorption in an impedance tube. The aim of the work is to propose a measuring experiment and to design measuring device with the intention of reducing costs. The aim is to carry out a measuring experiment on a manufactured measuring device. The results of the experiment are evaluated in terms of meeting the requirements formeasuring device. The results of the tested materials are compared with the values from the supplier.

Determination of Acoustic Properties of Sound-Absorbing Materials
Ďurica, Matej ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This diploma thesis is focused on experimental determination of acoustic absorption of four different material samples. The aims of the work include: research on the given issue, determination of the procedure for the performance of a technical experiment and modification of the measuring device for the determination of acoustic absorption. The performed experiments were evaluated and the results of the sound absorption coefficient were compared with the values given by the manufacturer. Sensitivity analyzes of the experiments were performed.
