In this master thesis we developed, constructed and analyzed the measurement system with a dynamic pressure generator, which will be used in investigations of frequency characteristics of pressure connecting tubes. The developed dynamic pressure generator consists of one electrodynamic loudspeaker that generates stable and adjustable periodic pressure pulsations inside the air chamber limited with the housing of the system. Dimensions of the pressure measuring ports were determined by taking into account dimensional characteristics of the piezoelectric pressure sensors and other connecting elements. The air chamber was designed with sufficiently large volume in order to minimize its effects on determination of frequency characteristics of the connecting tubes. In the LabVIEW programming environment we prepared a control program for computer supported measurements. We experimentally determined the amplitude and phase frequency characteristics of the dynamic pressure generator with associated pressure measuring system. In the frequency range from 1 to 500 Hz the amplitude and phase dynamic measurement errors of the pressure measure signals do not exceed 1.1 % and 0.6°, respectively.
