Personal computer and frequency analyzer measure reverberation time
View through CrossRef
This paper shows how a frequency analyzer (such as Brüel and Kjaer’s Model 2144) can be used to perform reverberation time measurements with the help of some extra software. Although a particular solution is presented, the concept can be applied to any frequency analyzer that has a programmable interface. Brüel and Kjaer’s Model 2144 is a powerful frequency analyzer, but it does not measure reverberation time. On the other hand, the analyzer has a programmable interface (GPIB) that permits us to control the instrument from a personal computer. This paper shows how a software application has been developed that gives the B&K2144 connected to a computer, the capacity of measuring reverberation time. The application has been developed using LabVIEW and it makes reverberation time measurements easy and reproducible.
