Abstract
The present work investigates the influence of different open headphone models on the perception of real sound sources in augmented audio reality applications. A set of binaural room impulse responses was measured with a dummy head wearing eight different open headphone configurations. A spectral error analysis showed strong deviations between the physical distortions in the real sound field caused by the different headphone models. The resulting perceptual effects were evaluated in a MUSHRA-like psychoacoustic experiment. The results show that all headphones introduce audible distortions. The extra-aural BK211 was found to be the one with the least audible corruption. In contrast, for some of the circumaural headphones strong coloration occurred and the spatial cues of the real sound sources were seriously affected.
