Wrapped into sound: Development of the Immersive Music Experience Inventory (IMEI).

Although virtual reality, video entertainment, and computer games are dependent on the three-dimensional reproduction of sound (including front, rear, and height channels), it remains unclear whether 3D-audio formats actually intensify the emotional listening experience. There is currently no valid inventory for the objective measurement of immersive listening experiences resulting from audio playback formats with increasing degrees of immersion (from mono to stereo, 5.1, and 3D).

Psychoacoustic optimization of a robust feedback active noise controller for headphones.

Broadband time-invariant feedback (FB) controllers can be designed to cancel unwanted noise components with a single error microphone on each side of a headphone. This paper presents an optimization routine based on the genetic algorithm (GA) approach to set the boundaries for a mixed-sensitivity H controller. The FB controllers are designed with the different target functions, sound pressure level (SPL), perceived loudness and perceived sharpness based on test signals with different spectral characteristics.

The Headphone and Loudspeaker Test - Part I: Suggestions for controlling characteristics of playback devices in internet experiments.

In internet experiments on auditory perception, playback devices may be a confounding variable reducing internal validity. A procedure to remotely test multiple characteristics of playback devices does not currently exist. Thus, the main goals of this study were to (i) develop and (ii) evaluate a comprehensive, efficient, and easy-to-handle test procedure for the reliable control and identification of playback device characteristics in online experiments.
