Frequency Estimation of the First Pinna Notch in Head-Related Transfer Functions with a Linear Anthropometric Model

Authors: Simone Spagnol, Federico Avanzini in: 18th International Conference on Digital Audio Effects (DAFx-15), Trondheim, 2015 Abstract: The relation between anthropometric parameters and Head-Related Transfer Function (HRTF) features, especially those due to the pinna, are not fully understood yet. In this paper we apply signal processing techniques to extract the frequencies of the main pinna notches (known as N1,… Continue Reading Frequency Estimation of the First Pinna Notch in Head-Related Transfer Functions with a Linear Anthropometric Model

Relative Auditory Distance Discrimination with Virtual Nearby Sound Sources

Authors: Simone Spagnol, Erica Tavazzi in: 18th International Conference on Digital Audio Effects (DAFx-15), Trondheim, 2015 Abstract: In this paper a psychophysical experiment targeted at exploring relative distance discrimination thresholds with binaurally rendered virtual sound sources in the near field is described. Pairs of virtual sources are spatialized around 6 different spatial locations (2 directions × 3 reference distances)… Continue Reading Relative Auditory Distance Discrimination with Virtual Nearby Sound Sources

Spatial Auditory Representation in the Case of the Visually Impaired People

Authors: Oana Bălan, Alin Moldoveanu, Florica Moldoveanu in: Journal of Information Systems & OperationsManagement, vol. 9, no. 1, May 2015,pp. 1-11 Abstract: Over the years, it has been widely believed that the blind individuals possess enhanced sound localization abilities that help them to navigate and orient in space in the lack of visual stimuli. In addition to this,… Continue Reading Spatial Auditory Representation in the Case of the Visually Impaired People

Introducing Basic Geometric Shapes to Visually Impaired People Using a Mobile App

Authors: Bogdan Troancă, Alexandru Butean, Alin Moldoveanu, Oana Bălan in: 12th National Conference on Human-Computer Interaction, Bucharest, 2015 Abstract: The problem of blindness and other eye diseases is highly important as it affects millions of people on the globe. In the same time, the number of modern touchscreen devices is increasing fast. They are widely spread and becoming accessible for education… Continue Reading Introducing Basic Geometric Shapes to Visually Impaired People Using a Mobile App

Auditory and Haptic Spatial Cognitive Representation in the Case of the Visually Impaired People

Authors: Oana Bălan, Alexandru Butean, Alin Moldoveanu, Florica Moldoveanu in: 22nd International Congress on Sound and Vibration, Florence, 2015 Abstract: Navigating in an unknown environment is a difficult task for the visually impaired people, as they are required to rely primarily on the haptic or auditory cues, in compensation for the lack of sight. However, their orientation and… Continue Reading Auditory and Haptic Spatial Cognitive Representation in the Case of the Visually Impaired People

3D Audio and Haptic Interfaces for Training the Spatial Acoustic Resolution in Virtual Auditory Environments

Authors: Oana Bălan, Alin Moldoveanu, Florica Moldoveanu in: 21st International Conference on Auditory Display (ICAD-2015), Graz, 2015 Abstract: In order to design an effective audio-based assistive device, we have to consider the users’ sound localization performance and spatial auditory resolution. As most of the virtual auditory displays employ 3D binaural sounds synthesized from non-individualized Head Related Transfer Functions… Continue Reading 3D Audio and Haptic Interfaces for Training the Spatial Acoustic Resolution in Virtual Auditory Environments

Haptic-Auditory Perceptual Feedback Based Training for Improving the Spatial Acoustic Resolution of the Visually Impaired People

Authors: Oana Bălan, Alin Moldoveanu, Hunor Nagy, György Wersényi, Nicolae Botezatu, Andrei Stan, Robert-Gabriel Lupu in: 21st International Conference on Auditory Display (ICAD-2015), Graz, 2015 Abstract: 3D binaural sounds play an important role in the development of navigational systems for the blind people. The use of generic HRTFs in virtual auditory displays significantly affects the acoustic spatial resolution and the listener’s… Continue Reading Haptic-Auditory Perceptual Feedback Based Training for Improving the Spatial Acoustic Resolution of the Visually Impaired People
