Acoustic Testing Model - Perceived Spatial Quality of Sound Processing and Reproducing Equipment
Summary Current models of audio testing measure `basic audio quality', using subjects to judge any difference. This leads to a perceived magnitude of distortions and a subjective acceptability. The QESTRAL acoustic testing model looks at any and all difference in the spatial attributes. Benefits Reduce the number of listening tests, which...

3D Soundscaping
Researchers at WSU have developed a 3D Soundscaping technology that enables one to take sound measurements to a new level by locating sound sources, visualize their resultant sound pressure fields in 3D space. In traditional sound sensing applications, sound is measured using microphones and sound pressure levels and spectra are measured at survey locations....
