Evaluation of Head Movements in Short-term Measurements and Recordings with Human Subjects using Head-Tracking Sensors

Authors: György Wersényi, J. Wilson in: Acta Technica Jaurinensis, Vol. 8, No.3, pp. 218-229, 2015 Abstract: Measurements for spatial hearing research, binaural recordings, virtual reality techniques etc. often rely on Head-Related Transfer Functions of human subjects and head-tracking techniques. Individually measured HRTFs and recordings on human heads may result in more accurate localization and sound… Continue Reading Evaluation of Head Movements in Short-term Measurements and Recordings with Human Subjects using Head-Tracking Sensors

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
