The software option 3PASS reverb extends these two software solutions (3PASS lab and 3PASS flex) with the ability to realistically and reproducibly simulate room reverberation of a single talker at the position of the device under test in a laboratory.
While an artificial head plays back the direct sound signal, the background noise system covers playback of the reverberation components based on the impulse response from the original room. 3PASS reverb operates with available equalized setups from 3PASS lab and 3PASS flex.
