This paper studies a novel personal listening device, HUMU Augmented Audio Cushion™, in the context of spatial audio. The case study explored ways to reproduce binaural audio with this device, which in normal use is located behind the listener. Several techniques were applied to binaural signals to render spatial sound, but none of them worked perfectly and bring the sound image in front of the listener. The device, which also provides tactile information for a user, is really close to the listener’s head, thus traditional far-field techniques failed to perform cross-talk cancellation. However, two listening tests revealed that the implemented techniques worked to some extent, however, many open research questions were left for future research.
