Sound Field Control in Surround Screen Speaker Array by WFS and CBT Algorithms

This paper proposes a method to solve the problem that the sound reproduction system cannot work when the movie screen is made by a sound-proof material such as LED. It is demonstrated in an array of 192 speakers to surround a screen for sound reproduction, called surround screen speaker array. The speaker array is built in an actual cinema. The sound field control algorithms are implemented by mixers. In order to improve the uneven sound field distribution and sound field aliasing caused by the speaker array, two algorithms WFS and CBT are used in this paper. A new control algorithm is proposed and demonstrated to improve the uniformity of the sound field distribution and reduce the sound field interference.

Dramaturgia muzyczna

In her paper, Ewa Wąchocka examines the phenomenon of recent dramatic works becoming increasingly more ‘musical’ and the terminological shift it brought about, i.e. the inclusion of the term ‘musical dramaturgy’ in writing for the stage. The author argues that far from being limited to the sounds of speech and language in general, musicality also encompasses a variety of non-musical sounds, the unravelling of the play’s narrative and the psychological makeup of its characters; it also penetrates deeply into the structure of the text. In the analysis of plays by W. Murek, A. Grzegorzewska, and S. Bogacz, the author demonstrates how essential the inspirations sourced from musical culture are for recent dramatic works: the 20th-century experiments with music, the discovery of how potent sound expression can be, or the most technologically advanced methods of sound reproduction. By presenting the many and varied dramatic strategies, the author shows that contemporary playwrights not only use musicality to represent the sound landscape of the world but, first and foremost, to create the ontology of an internally conflicted world.

Introduction

This introduction delineates the three main pillars of the book. Red music is defined within the context of the Vietnamese music industry and compared with propaganda music in other communist countries. The concept of a continuous revolution is described through reference to literature from political thinkers in Vietnam and the wider communist world. Radio and the voice are assessed as key themes in recent anthropological studies. This is followed by a review of the social history of sound reproduction, which is considered in the fields of ethnomusicology, sound studies, radio studies, and related fields. After outlining the research methodology (ethnographic and archival approaches) and structure of the book, the introduction concludes with notes on language, recordings, and musical transcriptions.

Perception of noise from small quadcopter UAVs

This paper presents the results of a study evaluating the human perception of the noise produced by small quadcopter UAVs. The study utilised recordings of the noise produced by several different quadcopter UAVs in hover and in constant-speed flight at a fixed altitude. These recordings were made using an eigenmic system. The recordings were reproduced using a 3D sound reproduction system located in the large anechoic chamber at the University of Auckland. Human subjects were asked to rate the annoyance of the recordings. The responses of the test subjects are presented and these are compared with objective metrics to assess suitable metrics for quantifying the impact of noise from these vehicles on humans.

Phono-stylistic features of small prose by E. Canetti

Linguistics as the science of language, its social nature and functions, the laws of its functioning, historical development includes many sections that consider various aspects of language - first of all, sounds (phonetics, phonology), words (morphology), sentences (syntax) and values (semantics). One of these sections is phono-stylistics, the task of which is to study the sound aspects of speech, the sound organization of the text, and sound effects in a work of art. The phonetic means of stylistics are the frequency of phonemes, sound repetitions, sound reproduction, and rhyme use. The study of a work of art from the point of view of phonetics plays a special role insofar as the analysis of the use of phonetic means (melody, rhythm, tempo, tone, accent, rate of speech, the use of certain sounds) in a text, sound support, stylistic meaning of the subtext helps to reveal the ideological intention of the author and to comprehend the aesthetic and emotional depth of a work. The purpose of this article is to consider the phono-stylistic, or rather rhythmic-intonational, features of Elias Canetti's short prose; for convenience, we will use the term “miniature”, “story” in this article, recognizing certain conventions within this genre modification.
