The new RT60 module enables measurement of the reverberation time (signal decay time) and clarity (ratio of early reverberations to late reverberations) of any room or space. This is often necessary for product designers to fully characterize test rooms, for example, for characterizing rooms for voice recognition testing in various environments. Since many such engineers are already using SoundCheck for their tests, it makes sense to include this additional functionality within the same package. This also provides the user the assurance that their room acoustics measurements are performed with calibrated signal paths. SoundCheck offers extremely fast measurements using a continuous sine sweep with the Log TSR algorithm to obtain the impulse response. The reverberation decay curve is calculated from the backwards integrated impulse response. Aside from its speed, this method offers other significant advantages over the traditional direct method – it requires just one measurement at each location, and minimizes the effect of noise and distortion on the measurement. A free test sequence for characterizing the room is available.
