Processing of emotional words in bilinguals: Testing the effects of word concreteness, task type and language status

Ferré, Pilar ; Anglada-Tort, Manuel ; Guasch, Marc (2017-12-19)

The present study investigates whether the emotional content of words has the same effect in the different languages of bilinguals by testing the effects of word concreteness, the type of task used, and language status. Highly proficient bilinguals of Catalan and Spanish who learned Catalan and Spanish in early childhood in a bilingual immersion context, and who still live in such a context, pe...

Room Acoustical Parameters as Predictors of Room Acoustical Impression: What Do We Know and What Would We Like to Know?

Weinzierl, Stefan ; Vorländer, Michael (2015-02-26)

Room acoustical parameters are audio features, usually extracted from monaural or binaural measurements of room acoustical environments, and used to predict different aspects of the ‘room acoustical impression’. The paper takes a closer look at the nature of this perceptional construct and at different approaches to develop a psychological measuring instrument for the multidimensional perceptio...

Generation and analysis of an acoustic radiation pattern database for forty-one musical instruments

Shabtai, Noam R. ; Behler, Gottfried ; Vorländer, Michael ; Weinzierl, Stefan (2017-02-28)

A database of acoustic radiation patterns was recorded, modeled, and analyzed for 41 modern or authentic orchestral musical instruments. The generation of this database included recordings of each instrument over the entire chromatic tone range in an anechoic chamber using a surrounding spherical microphone array. Acoustic source centering was applied in order to align the acoustic center of th...

Instruments for Spatial Sound Control in Real Time Music Performances. A Review

Pysiewicz, Andreas ; Weinzierl, Stefan (2016-12-10)

The systematic arrangement of sound in space is widely considered as one important compositional design category of Western art music and acoustic media art in the 20th century. A lot of attention has been paid to the artistic concepts of sound in space and its reproduction through loudspeaker systems. Much less attention has been attracted by live-interactive practices and tools for spatialisa...

Mixed Analytical-Numerical Filter Design for Optimized Electronic Control of Line Source Arrays

Straube, Florian ; Schultz, Frank ; Makarski, Michael ; Weinzierl, Stefan (2018-09-16)

Line source arrays (LSAs) are used for large-scale sound reinforcement that synthesizes homogeneous sound fields over the full audio bandwidth. The deployed loudspeaker cabinets are rigged with different tilt angles and are electronically controlled to provide the intended coverage of the audience zones and to avoid radiation toward the ceiling, reflective walls, or residential areas. In this a...

Prediction of speech intelligibility using pseudo-binaural room impulse responses

Kokabi, Omid ; Brinkmann, Fabian ; Weinzierl, Stefan (2019-04-29)

Head orientation (HO) affects better-ear-listening and spatial-release-from-masking, which are two key aspects in binaural speech intelligibility. To incorporate HO in speech intelligibility prediction, binaural room impulse responses (BRIRs) for every HO of interest could be used. Due to the limited spectral bandwidth of speech, however, approximate representations might be sufficient, which c...

Segmentation of binaural room impulse responses for speech intelligibility prediction

Kokabi, Omid ; Brinkmann, Fabian ; Weinzierl, Stefan (2018-11-16)

The two most important aspects in binaural speech perception—better-ear-listening and spatial-release-from-masking—can be predicted well with current binaural modeling frameworks operating on head-related impulse responses, i.e., anechoic binaural signals. To incorporate effects of reverberation, a model extension was proposed, splitting binaural room impulse responses into an early, useful, an...

Audibility and Interpolation of Head-Above-Torso Orientation in Binaural Technology

Brinkmann, Fabian ; Roden, Reinhild ; Lindau, Alexander ; Weinzierl, Stefan (2015-03-20)

Head-related transfer functions (HRTFs) incorporate fundamental cues required for human spatial hearing and are often applied to auralize results obtained from room acoustic simulations. HRTFs are typically available for various directions of sound incidence and a fixed head-above-torso orientation (HATO). If-in interactive auralizations-HRTFs are exchanged according to the head rotations of a ...

A Virtual-Reality Reconstruction of Poème Électronique Based on Philological Research

Lombardo, Vincenzo ; Valle, Andrea ; Fitch, John ; Tazelaar, Kees ; Weinzierl, Stefan ; Borczyk, Wojciech (2009-05-20)


Binaural processing for the evaluation of acoustical environments

Brinkmann, Fabian (2019)

The main concern of this work is binaural processing for acoustical environments, and the evaluation of room acoustical simulations against the corresponding real sound fields. For this purpose the real sound fields and the simulations were virtualized by means of binaural synthesis - a method that aims at reproducing the sound pressure signals at the listener's ear drums. Before the compariso...

Discovering and interpreting audio media generation units: A typological-praxeological approach to the mediatization of everyday music listening

Lepa, Steffen ; Hoklas, Anne-Kathrin ; Weinzierl, Stefan (2014-11)

To deal with methodological challenges, which confront current mediatization research due to the ongoing digitalization of media, we suggest a mixed methods approach that is an adopted form of media repertoire analysis based on the generation unit concept of Karl Mannheim. Essentially, we propose that discovery and life cycle analysis of culturally meaningful media generation units may be achie...

A High Resolution and Full-Spherical Head-Related Transfer Function Database for Different Head-Above-Torso Orientations

Brinkmann, Fabian ; Lindau, Alexander ; Weinzierl, Stefan ; van de Par, Steven ; Müller-Trapet, Markus ; Opdam, Rob ; Vorländer, Michael (2017-10)

Head-related transfer functions (HRTFs) capture the free-field sound transmission from a sound source to the listeners ears, incorporating all the cues for sound localization, such as interaural time and level differences as well as the spectral cues that originate from scattering, diffraction, and reflection on the human pinnae, head, and body. In this study, HRTFs were acoustically measured a...

A Mobile App for Geolocalized, Dynamic Binaural Synthesis

Hädrich, Markus ; Lindau, Alexander ; Weinzierl, Stefan (2016)

Today, technical evolution and dissemination of smartphones have reached a point where powerful mobile computing has become virtually ubiquitous. Additionally, devices are equipped with a multitude of sensors and interfaces allowing for a – potentially continuous – acquisition of optical and acoustical data, the continued determination of bearing and position, and mobile network connectivity. T...
