Acoustic verification of rectangular reverberation chamber using impulse sound source

Popis výsledku v původním jazyce

There are various methods for determining the acoustic quantities of materials, machines, equipment, and their sub-assemblies. A suitable measurement procedure for a given purpose depends on the frequency range of interest and the required precision. Nowadays, most laboratories deal with the effective measurement management system which ensures that the measurement processes are fit for their intended use, and furthermore, it leads to managing the risk of incorrect measurement results. However, this management system is mainly focused on the generic requirements and routine metrological confirmation of measuring equipment. This approach is essential especially in the large organization performing measurements, although it does not ensure the correct measured data. In the case of acoustic laboratories, in addition to the precision of measuring equipment, has equal importance the properties of environment where the measurement takes place. This paper describes an experimental process to identify the acoustic properties of reverberation chamber which proportions, shape and construction material of boundary surfaces are not in compliance with standards in every detail. In the following, the subsequent acoustic treatments to extend the measured frequency range, are discussed.
