Abstract [en]

Qualities of loudness meters were investigated by running a simulated live broadcast show, mixed by subjects with different degrees of audio engineering experience. The subject-induced fader movements and the resulting output levels were analyzed using a general linear mixed model and then interpreted according to a proposed set of quality criteria for live loudness meters. The results show that, for subparts of the program. meters with slower integration lime caused less dispersion of the resulting output levels and a smaller error to a given target level. The varying integration tunes of the meters did not cause any significant differences in reaction time. It is concluded that this type of data may be used in evaluation of loudness meters and the specific study provides insight into the effect of time scales and meter implementation for EBU R 128-compliant meters.

Abstract [en]

The artistic research project ‘Room for interpretation’ addresses questions concerning the influence of room acoustics on the performance of Western art music from the performers’ perspective. The empirical core of the project is a number of experimental performance sessions carried out in Studio Acusticum, Piteå, a concert hall with mechanically variable acoustics. The authors discuss issues relating to the project’s design and methodology; the focus of the article is thus the research process rather than the results. A presentation of the project, its preconditions, goals, design and methodology is followed by an overview of previous research, mostly in acoustic science, on the same or closely related topics. In the third part of the article, characteristics of the present project are compared to those of the previous studies. In the following part, ’Room for interpretation’ is related to the ongoing discussion on the purposes and means of artistic research. The authors argue that the project, while showing certain similarities to previous studies, differs considerably with respect to aims and important aspects of design, and that its characteristic features agree well with those usually regarded as typical of artistic research. The article concludes with a summary of the most important results concerning: differences between performers’ reactions in the live situation and when listening to their own recordings; differences between chamber ensembles, conducted ensembles and soloists as to the influence of the acoustics on the performance; and the prevalence of sound over other musical parameters in performers’ comments on their recorded performances.

Abstract [en]

In-ear monitors for live performances are commonly considered to give better sound quality than loudspeaker monitors. They are also often assumed to reduce sound exposure. Because of lack of evidence for this, sound exposure for pop/rock/jazz musicians was compared between performances with in-ear and loudspeaker monitors. Equivalent sound pressure levels at the musicians' ears were 94 to 105 dBA with loudspeaker and 86 to 108 dBA with in-ear monitors. Many participants used earplugs when using loudspeaker monitors. Therefore, the recommendation, from a pure hearing protection perspective, is to use loudspeaker monitors and earplugs. However, the large spread in levels between musicians using in-ear monitors suggests that with better training and measurements of sound exposure, in-ear monitors could be used safely.

Abstract [en]

A successful performance of live music is dependent on how well musicians can hear themselves and the other members of the ensemble. Sound reinforcement systems can offer monitoring either by on-stage loudspeakers or in-ear headphones. These two monitoring conditions were compared to search for perceived auditory differences that affect parts of musical performance. Four jazz/pop/rock bands made live performances where monitor sound was provided to the musicians. Each band repeated their performance, changing from one monitoring condition to the other. After every performance, the musicians responded to questionnaires covering musical performance and audio quality. Experts also assessed recordings of the performances. Results show that perceived differences exist in audio quality and musical performance between loudspeaker monitors and in-ear headphone monitors.

Abstract [en]

In natural history filmmaking recording fauna vocalisation often produces difficult challenges especially when recording sound from a distance. The camera in many cases is able to solve these problems due to lens changes, but the microphone cannot do this, which creates major problems when combining sound and picture. This thesis using a multi disciplinary approach, looks at these problems in particular the 'Distance' and 'On-Axis' issues and attempts to solve them using both a theoretical and practical approach. The thesis consists of two parts, part one the theoretical section discusses the idiosyncrasies of natural history sound recording giving examples where the problems of actual situations have been resolved. Part two is an applied method or practical experimentation using technology designed to test certain theories in effectively dealing with the 'Distance' and 'On-Axis' issues. The practical experimentation takes place at various locations using avian subjects to demonstrate the problems and solutions when recording wildlife vocalisation. As a result of the tests, a remote-controlled microphone operating system was developed and tested in the field to ascertain its capabilities. Although still a prototype it has the potential through further development, to be a useful technological instrument for recording wildlife sound.

Abstract [en]

Audio quality is of concern up and down the production chain from content creation to distribution. The technologies employed at each step - equipment, processors like codecs, downmix algorithms and loudspeakers - all are scrutinized for their impact. The now well-established field of audio quality research has developed robust methods for assessments. To form a basis for this work, research has investigated how perceptual dimensions are formed and expressed. The literature includes numerous sonic attributes that may be used to evaluate audio quality. All together, these findings have provided benchmarks and guidelines for improving audio technology, setting standards in the manufacture of sound and recording equipment, and furthering the design of reproduction systems and spaces. They are, however, by comparison rarely used to inform recording and mixing practice. In this paper quality evaluation and mixing practice are compared on selected counts and observations are made on what points these fields may mutually inform one another

Abstract [en]

Concert hall acoustics is an important factor that influences musical performance. Different acoustics lead to different musical results. For a musical performer, the artistic impression of a performance is paramount. Therefore, it is essential to study the relation between concert hall acoustics and musical performance. Such studies might also be relevant for architects and acousticians. A pilot study was devised, enabled by a unique concert hall with mechanically variable acoustics. A musician played the grand piano at four trials, each having a distinctive acoustic condition. The trials were recorded for later analysis. The performances were assessed by experts and the pianist himself. The results show that clear as well as subtle differences in interpretation and performance between the trials existed.
