Ackermann, David ; Ilse, Maximilan ; Grigoriev, Dmitry ; Lepa, Steffen ; Pelzer, Sönke ; Vorländer, Michael ; Weinzierl, Stefan (2018-05)

A database of 35 virtual room models was created that can serve as a ground truth for the future development of room acoustical parameters beyond ISO 3382-1. Some of the room models are based on existing performance venues, however without yielding a perfect match of measured and simulated acoustical parameters. Others are artificial designs which were made to systematically cover a wide variet...

On the epistemic potential of virtual realities for the historical sciences. A methodological framework

Weinzierl, Stefan ; Lepa, Steffen (2017)

Virtual or augmented audio-visual environments can be employed not only for the impartment of knowledge to a wider audience, but also for the generation of knowledge within the historical sciences. In this context, the transformation of numerical models of historical circumstances into an immediate sensual experience may be used both in an exploratory manner as well as for testing specific hypo...

Kokabi, Omid ; Brinkmann, Fabian ; Weinzierl, Stefan (2018-03-14)

This document is supplement to "Assessment of speech perception based on binaural room impulse responses", a master thesis realized at the audio communication group at Technische Universität Berlin. In this thesis, the prediction accuracy with a binaural intelligibility model with an extension to model the influence of reverberation was tested for four different virtual rooms. Therefore, speech...

Extending the closed-form image source model for source directivity (Digital appendix)

Erbes, Vera ; Brinkmann, Fabian (2018-03-12)

The image source model (ISM) is a widespread tool in geometrical room acoustic simulation for the generation of early reflections, which can take into account the source and receiver directivity, as well as the absorption properties of the acoustic environment. A downside of the ISM is the increase in computational effort with increasing image source order caused by costly visibility checks tha...

Hearing a shakkei: The semiotics of the audible in a Japanese stroll garden

Fowler, Michael (2013)

Though there has been some interest in the semiotics of Japanese gardens (Casalis 1983; van Tonder and Lyons 2005) as pure visual articulations of landscape elements, attention to what Schafer (1977) and Truax (2001) identify as a garden's soundscape has been lacking. This paper investigates the gardening technique of shakkei (borrowed scenery) in the Tokyo garden Kyu Furukawa Teien. Utilizing ...

Alvin Lucier's Music for Solo Performer: Experimental music beyond sonification

Straebel, Volker ; Thoben, Wilm (2014)

Alvin Lucier's Music for Solo Performer (1965), often referred to as the ‘brain wave piece’, has become a key work of experimental music. Its setup, in which the brain waves of a solo performer are made to excite percussion instruments, has given the work a central place in the discourse on artistic sonification. However, only a small number of the authors making reference to the work seem to h...

Sound, materiality and embodiment challenges for the concept of 'musical expertise' in the age of digital mediatization

Lepa, Steffen ; Hoklas, Anne-Kathrin ; Egermann, Hauke ; Weinzierl, Stefan (2015)

Within academic music research, 'musical expertise' is often employed as a 'moderator variable' when conducting empirical studies on music listening. Prevalent conceptualizations typically conceive of it as a bundle of cognitive skills acquired through formal musical education. By implicitly drawing on the paradigm of the Western classical live concert, this ignores that for most people nowaday...

The Repeated Recording Illusion

Anglada-Tort, Manuel ; Müllensiefen, Daniel (2017-09)

The repeated recording illusion refers to the phenomenon in which listeners believe to hear different musical stimuli while they are in fact identical. The present paper aims to construct an experimental paradigm to enable the systematic measurement of this phenomenon, investigating potentially related extrinsic and individual difference factors. Participants were told to listen to ‘‘different’...

Predicting musical meaning in audio branding scenarios

Herzog, Martin ; Lepa, Steffen ; Steffens, Jochen ; Schoenrock, Andreas ; Egermann, Hauke (2017)

This paper describes the concept of applying automatic music recommendation to the audio branding domain. We describe our approach of developing a prediction model for the perceived expressive content of music which is based on a large-scale listening experiment. We present an orthogonal 4-factor model for measuring musical expression as outcome variable, whereas audio- and music features as we...

Towards automatic music recommendation for audio branding scenarios

Herzog, Martin ; Lepa, Steffen ; Egermann, Hauke (2016)

Within the MIR community, most prediction models of musical impact on listeners focus on mood or emotional effects (perceived or induced). The ABC_DJ project investigates the associative impact of music on listeners from the specific perspective of music branding that surrounds us in our everyday lives. We pre-sent a general concept for applying automatic music rec-ommendation within this domai...
