The implementation of simple virtual source models like plane and spherical waves in wave field synthesis employs delays which are applied to the input signals. We present a formal experiment evaluating the perceptual consequences of different accuracies of these delays. Closely related to the question of delay accuracy is the accuracy of the loudspeaker positioning. The second part of the pres...

Auditory stimulation with monaural or binaural auditory beats (i.e. sine waves with nearby frequencies presented either to both ears or to each ear separately) represents a non-invasive approach to influence electrical brain activity. It is still unclear exactly which brain sites are affected by beat stimulation. In particular, an impact of beat stimulation on mediotemporal brain areas could po...

Binaural models attempt to explain binaural phenomena in terms of neural mechanisms that extract binaural information from acoustic stimuli. In this paper, a model setup is presented that can be used to simulate binaural detection tasks. In contrast to the most often used cross correlation between the right and left channel, this model is based on contralateral inhibition. The presented model i...

An audio-visual localisation and tracking system for meeting scenarios is presented which draws its inspiration from neurobiological processing. Meetings are recorded by a KEMAR binaural manikin and a single camera placed directly above the manikin. Source localisation from the binaural audio and face, object and motion locations from the video frames are used as input to two linked neural osci...

While human listening is robust in complex auditory scenes, current speech segregation algorithms do not perform well in noisy and reverberant environments. This paper addresses the robustness in binaural speech segregation by employing binary classification based on deep neural networks (DNNs). We systematically examine DNN generalization to untrained configurations. Evaluations and comparison...

Speech intelligibility can be substantially improved when speech and interfering noise are spatially separated. This spatial unmasking is commonly attributed to effects of head shadow and binaural auditory processing. In reverberant rooms spatial unmasking is generally reduced. In this study spatial unmasking is systematically measured in reverberant conditions for several configurations of bin...

We present an approach to automatically extract and re-render a structured auditory scene from field recordings obtained with a small set of microphones, freely positioned in the environment. From the recordings and the calibrated position of the microphones, the 3D location of various auditory events can be estimated together with their corresponding content. This structured description is rep...

This study examines the effects of background noise, actual source distance, and room reverberation on the perceived distance of a single phrase of recorded speech reproduced at a naturalistic sound pressure level. A simple rectangular room was used for stimulus generation, wherein binaural recordings were made with source-receiver distances between 0.9 m and 5.1 m, reverberation times between ...

Partial tracking in sinusoidal models have been studied for over twenty years now, and have been enhanced, making it precise and useful to analyse noiseless harmonic sounds. However, such tools have always been used in a monophonic (single channel) context. A method is thus proposed to adapt the partial tracking to the case of binaural signals. This gives a tool to perform spectral analysis of ...
