This work investigates the associations between objectively measured distance metrics and subjective assessments of similarity in HRTF data. For this purpose two different means of matching users to HRTF sets were compared: a simple system computing correlations between personally collected HRTF data and a repository of 111 measured binaural datasets, and an HRTF user-preference study assessing...

This article presents a novel framework to register and fuse heterogeneous sensory data. Our approach is based on geometrically registration of sensory data onto a set of virtual parallel planes and then applying an occupancy grid for each layer. This framework is useful in surveillance applications in presence of multi-modal sensors and can be used specially in tracking and human behavior unde...

How do we describe the exemplary acuity of humans to analyze and respond to sounds, particularly to music? Is our current knowledge sufficient to produce working computational models for such sensations? Has our perspective for the conceptual structure of such models changed and why is this important? This work attempts to provide brief answers to these questions, focusing on a recent comprehen...

| We present a real time DSP implementation of a novel binaural sound synthesis system designed for natural and realistic sound reproduction by means of headphones. The application area is multi media and virtual reality. The processing system is designed such that a sound source can be simulated on several spatial positions around the listener. Also moving sources and binaural reverberation ar...

The human auditory system is known to be able to easily analyze and decompose complex acoustic scenes into its constituent acoustic sources. This requires the integration of a multitude of acoustic cues, a phenomenon that is often referred to as cocktail-party processing. Auditory Scene Analysis, especially the segregation and comprehension of concurrent speakers, is one of the key features in ...

Historically, most of the metrics that have been used to evaluate the effectiveness of military communications systems have focused on measuring the intelligibility of a single talker in the presence of a continuous noise masker. However, many critical military operations involve complex communications tasks that require listeners to monitor, process, and respond to two or more simultaneous spe...

We study a system combining adaptive feedback cancellation and adaptive filtering connecting inputs from both ears for signal enhancement in hearing aids. For the first time, such a binaural system is analyzed in terms of system stability, convergence of the algorithms, and possible interaction effects. As major outcomes of this study, a new stability condition adapted to the considered binaura...

Effective control of the perceived location of virtual sound sources is an important aspect of auditory displays. While room acoustics modelling may be used to produce cues related to the sound source and listener location in a space, in many real-time applications it is more feasible to utilize ready-made room impulse responses. This paper looks at how the perception of distance can be affecte...

When a listener is surrounded by multiple loudspeakers, some of which are located above and/or below him/her, an immersive threedimensional auditory display can be created with vector base amplitude panning (VBAP). In VBAP a complex loudspeaker layout is divided to loudspeaker triplets or pairs (sets). A sound signal is applied to loudspeakers of one set with different gain factors at one time,...

This paper proposes a novel speech-fragment based approach for processing binaural data to improve the estimation of speech source locations in reverberant, multi-speaker recordings. The technique employs two stages. First, a robust multipitch tracking algorithm is used to locate local spectro-temporal ‘speech fragments’ – regions where the energy in the mixture is dominated by a single speech ...
