Abstract
The paper presents the concept, structure and properties of a portable analyzer, allowing the study of the sound-profile of enclosed spaces (concert halls, auditorium, religious buildings, etc.) and open facilities (stadiums, concert shells, etc.) The portability of the analyzer allows for analysis of acoustic properties in selected locations of sound-reinforced object. The device performs a spectral analysis of the acoustic signal, which arises after connecting a particular test signal to the sound-reinforcement system, such as pink noise, white or a sinusoidal signal or an arbitrary signal, created by the user and stored on flash memory. In addition, the analyzer carries out the measurement of reverberation time and indoor sets rate speech intelligibility (RASTI).
