Reichmuth, C. 2012. Adventures in Bioacoustics: Sound Reception

Adventures in bioacoustics: Sound reception, production, and perception in amphibious mammals The 2012 Annual Conference of the Canadian Acoustical Association. Banff, Alberta, 10-12 October. Keynote address: Dr. Colleen Reichmuth, Research Scientist, Long Marine Laboratory, University of California Santa Cruz The songs of whales and sonar of dolphins readily come to mind when thinKing of the unique acoustics of marine mammals, but equally curious are the ways in which sea otters, seals, sea lions, and walruses use sound above and below the water's surface. The amphibious lifestyles of these marine mammals present special challenges to their sensory structures and interesting opportunities for comparative study. This talK will present a personal perspective on the bioacoustics of marine carnivores gathered from an assortment of laboratory and field studies conducted over the last 20 years. The methods used for this research include psychoacoustics, cognitive testing, analysis of communicative signaling, playbacK experiments, and in vivo studies of sound production. Dr. Reichmuth is an animal behaviorist with a PhD in Ocean Sciences. Her research program is based at Long Marine Laboratory at the University of California Santa Cruz, and it includes an eclectic group of students from psychology, organismal biology, oceanography, and environmental studies and an equally eclectic group of trained marine mammals that participate in a variety of cognitive, sensory, and behavioral research projects. She has worKed closely with California sea lions, harbor seals, elephant seals, ringed seals, spotted seals, walruses and sea otters, often using operant training methods to explore their perceptual capabilities. A major focus of her current research is using psychoacoustic tools to determine the potential deleterious effects of noise on hearing in marine mammals. .

The physics of sound define the corner stones of this communicative framework, which is employed by animal groups from insects to mammals, of which examples of vocalisations are presented. Recording bioacoustic signals allows reproducible identification and documentation of species’ occurrences, but it requires technical prerequisites and behavioural precautions that are summarized. The storing, visualizing and analysing of sound recordings is illustrated and major software tools are shortly outlined. Finally, different approaches to bioacoustic monitoring are described, tips for setting up an acoustic inventory are compiled and a key for procedural advancement and a checklist to successful recording are given.

Abstract Musical behavior is likely as old as our species with song originating as early as 60 million years ago in the primate order. Early singing likely evolved into the music of modern humans via multiple selective events, but efforts to disentangle these influences have been stifled by challenges to precisely define this behavior in a broadly applicable way. Detailed here is a method to quantify the elaborateness of acoustic displays using published spectrograms (n=832 calls) culled from the literature on primate vocalizations. Each spectrogram was scored by five trained analysts via visual assessments along six musically relevant acoustic parameters: tone, interval, transposition, repetition, rhythm, and syllabic variation.

Moka, Vibha Viswanathanb, Agudemu Borjiginb, Ravinderjit Singhb, Homeira Kafib, and ∗Hari M. Bharadwaja,b aDepartment of Speech, Language, and Hearing Sciences, Purdue University, West Lafayette, IN, United States bWeldon School of Biomedical Engineering, Purdue University, West Lafayette, IN, United States Abstract Anonymous web-based experiments are increasingly and successfully used in many domains of behavioral research. However, online studies of auditory perception, especially of psychoacoustic phe- nomena pertaining to low-level sensory processing, are challenging because of limited available control of the acoustics, and the unknown hearing status of participants. Here, we outline our approach to mitigate these challenges and validate our procedures by comparing web-based measurements to lab- based data on a range of classic psychoacoustic tasks. Individual tasks were created using jsPsych, an open-source javascript front-end library. Dynamic sequences of psychoacoustic tasks were imple- mented using Django, an open-source library for web applications, and combined with consent pages, questionnaires, and debriefing pages. Subjects were recruited via Prolific, a web-based human-subject marketplace. Guided by a meta-analysis of normative data, we developed and validated a screening pro- cedure to select participants for (putative) normal-hearing status; this procedure combined thresholding of scores in a suprathreshold cocktail-party task with filtering based on survey responses.

Psychoacoustics and Its Benefit for the Soundscape
ACTA ACUSTICA UNITED WITH ACUSTICA Vol. 92 (2006) 1 – 1 Psychoacoustics and its Benefit for the Soundscape Approach Klaus Genuit, André Fiebig HEAD acoustics GmbH, Ebertstr. 30a, 52134 Herzogenrath, Germany. [klaus.genuit][andre.fiebig]@head- acoustics.de Summary The increase of complaints about environmental noise shows the unchanged necessity of researching this subject. By only relying on sound pressure levels averaged over long time periods and by suppressing all aspects of quality, the specific acoustic properties of environmental noise situations cannot be identified. Because annoyance caused by environmental noise has a broader linkage with various acoustical properties such as frequency spectrum, duration, impulsive, tonal and low-frequency components, etc. than only with SPL [1]. In many cases these acoustical properties affect the quality of life. The human cognitive signal processing pays attention to further factors than only to the averaged intensity of the acoustical stimulus. Therefore, it appears inevitable to use further hearing-related parameters to improve the description and evaluation of environmental noise. A first step regarding the adequate description of environmental noise would be the extended application of existing measurement tools, as for example level meter with variable integration time and third octave analyzer, which offer valuable clues to disturbing patterns. Moreover, the use of psychoacoustics will allow the improved capturing of soundscape qualities. PACS no. 43.50.Qp, 43.50.Sr, 43.50.Rq 1.

Music Education and Music Psychology: What‟S the Connection? Research Studies in Music Education
Music Psychology and Music Education: What’s the connection? By: Donald A. Hodges Hodges, D. (2003) Music education and music psychology: What‟s the connection? Research Studies in Music Education. 21, 31-44. Made available courtesy of SAGE PUBLICATIONS LTD: http://rsm.sagepub.com/ ***Note: Figures may be missing from this format of the document Abstract: Music psychology is a multidisciplinary and interdisciplinary study of the phenomenon of music. The multidisciplinary nature of the field is found in explorations of the anthropology of music, the sociology of music, the biology of music, the physics of music, the philosophy of music, and the psychology of music. Interdisciplinary aspects are found in such combinatorial studies as psychoacoustics (e.g., music perception), psychobiology (e.g., the effects of music on the immune system), or social psychology (e.g., the role of music in social relationships). The purpose of this article is to explore connections between music psychology and music education. Article: ‘What does music psychology have to do with music education?’ S poken in a harsh, accusatory tone (with several expletives deleted), this was the opening salvo in a job interview I once had. I am happy, many years later, to have the opportunity to respond to that question in a more thoughtful and thorough way than I originally did. Because this special issue of Research Studies in Music Education is directed toward graduate students in music education and their teachers, I will proceed on the assumption that most of the readers of this article are more familiar with music education than music psychology.

Short abstract How did music evolve? We show that prevailing views on the evolution of music — that music is a byproduct of other evolved faculties, that music evolved for social bonding, and that music evolved to signal mate quality — are incomplete or wrong. We argue instead that music evolved as a credible signal in at least two contexts: coalitional interactions and infant care. We suggest that basic features of music, including melody and rhythm, result from adaptations in the proper domain of human music, providing a foundation that cultural evolution shapes into its actual domain. Long abstract Music comprises a diverse category of cognitive phenomena that likely represent both the effects of psycho- logical adaptations that are specific to music (e.g., rhythmic entrainment) and the effects of adaptations for non-musical functions (e.g., auditory scene analysis).
