Conventional Systems

Recently, with the development of video technology, 3-D sound field reproduction systems that can provide a high presence have attracted attention. Conventional systems with electro-dynamic loudspeakers have a problem that the sound image lacks sharpness when constructing a narrow sound image. To solve this problem, we utilize a parametric array loudspeaker which has sharp directivity by the straightness of ultrasounds. Parametric array loudspeakers can produce sharper sound images due to the sharper directivity and lower reverberation compared with electro-dynamic loudspeakers. However, it is difficult to represent reverberation by parametric array loudspeakers. In this paper, we propose a method for 3-D sound field reproduction to achieve both the sharp images and reverberation presence by combing parametric array loudspeakers and electro-dynamic loudspeakers in surround sound system. In the proposed method, sharp sound images are rendered by parametric array loudspeakers and the reverberation presence is provided by electro-dynamic loudspeakers, emitting reverberation signals synthesized with a reverberation control filter. The reverberation control filter is adaptively designed to reproduce the reverberation time and the direct-to-reverberation ratio of the target sound field in other environments. The experimental results show that the proposed method can achieve the reproducing the sharp sound image with some reverberation presence.

The Aesthetic

Primer is a very low budget science-fiction film that deals with the subject of time travel; however, it looks and sounds quite distinctively different from other films associated with the genre. While Hollywood blockbuster sci-fi relies on “sound spectacle” as a key attraction, in contrast Primer sounds “lo-fi” and screen-centred, mixed to two channel stereo rather than the now industry-standard 5.1 surround sound. Although this is partly a consequence of the economics of its production, the aesthetic approach to the soundtrack is what makes Primer formally distinctive. Including a brief exploration of the role of sound design in science-fiction cinema more broadly, I analyse aspects of Primer’s soundtrack and sound-image relations to demonstrate how the soundplays around with time rather than space, substituting the spatial playfulness of big-budget Hollywood sci-fi blockbuster sound with temporal playfulness, in keeping with its time-travel theme. I argue that Primer’s aesthetic approach to the soundtrack is “anti-spectacle”, working with its mise-en-scène to emphasise the mundane and everyday instead of the fantastical, in an attempt to lend credibility and “realism” to its time-travel conceit. Finally, with reference to scholarship on American independent cinema, I will demonstrate how Primer’s stylistic approach to the soundtrack is configured as a marketable identifier of its “indie”-ness.

Art Pedagogy

The proposed material examines the creative task of students majoring in Social Pedagogy at the University „Prof. Dr. Assen Zlatarov“ in Burgas, and studying the discipline Art Pedagogy – Part 1 – Music. In the course of the lecture course students get acquainted with the elements of musical expression, as a means of figurative representations and impact of music, with different techniques concerning individual musical activities, with the endless and diverse opportunities that music provides in the use of art pedagogy for social work teachers.Verbal interpretation of music is a necessary component when working with children with special educational needs, at risk and in the norm. Looking at Tchaikovsky’s short and extremely figurative piano piece „The Sick Doll“ from his charming „Children’s Album“, in the form of a short story, tale or essay, students express their personal vision, feeling and transformation of the musical image. The aim of the task is to transcribe the sound image into a verbal one. This requires speed, flexibility and logic in thinking, through imagination and creativity in its manifestation. Children love to listen, especially when they are involved. In search of the right way to solve problems and situations, future social educators could successfully benefit from the conversion of sound into words, according to the needs and deficits of the individual or group.
