Nevertheless, there is no unied approach that relates these elements to the discrete samples of digitized sound. In this article, each musical element is related by equations and algorithms to the discrete-time samples of sounds, and each of these relations are implemented in scripts within a soware toolbox, referred to as MASS (Music and Audio in Sample Sequences). e fundamental element, the musical note with duration, volume, pitch and timbre, is related quantitatively to characteristics of the digital signal. Internal variations of a note, such as tremolos, vibratos and spectral uctuations, are also considered, which enables the synthesis of notes inspired by real instruments and new sonorities. With this representation of notes, resources are provided for the generation of higher scale musical structures, such as rhythmic meter, pitch intervals and cycles. is framework enables precise and trustful scientic experiments, data sonication and is useful for education and art. e ecacy of MASS is conrmed by the synthesis of small musical pieces using basic notes, elaborated notes and notes in music, which reects the organization of the toolbox and thus of this article.

Where environmental sounds (e.g., outdoor traffic sounds) are often perceived as negative, a soundscape (e.g., containing natural sounds) can also have a positive effect on health and well-being. This supportive effect of a soundscape is getting increasing attention for use in practice. This paper addresses the design of a supportive sonic environment for persons with dementia in nursing homes. Starting from a review of key mechanisms related to sonic perception, cognitive deficits and related behavior, a framework is derived for the composition of a sonic environment for persons with dementia.

  • CAN't GET IT out of MY HEAD: BRAIN DISORDER CAUSES MYSTERIOUS MUSIC HALLUCINATIONS , February 28, 2004 the Sunday Telegraph Maga
    CarlZimmer.com 7/20/05 12:19 PM CAN'T GET IT OUT OF MY HEAD: BRAIN DISORDER CAUSES MYSTERIOUS MUSIC HALLUCINATIONS The Sunday Telegraph Magazine, February 28, 2004 Janet Dilbeck clearly remembers the moment the music started. Two years ago she was lying in bed on the California ranch where she and her husband were caretakers. A mild earthquake woke her up. To Californians, a mild earthquake is about as unusual as a hailstorm, so Dilbeck tried to go back to sleep once it ended. But just then she heard a melody playing on an organ, "very loud, but not deafening," as she recalls. Dilbeck recognized the tune, a sad old song called When You and I Were Young, Maggie. Maggie was her mother's name, and when Dilbeck (now 70) was a girl her father would jokingly play the song on their home organ. Dilbeck is no believer in ghosts, but as she sat up in bed listening to the song, she couldn't help but ask, "Is that you, Daddy?" She got no answer, but the song went on, clear and loud. It began again from the beginning, and continued to repeat itself for hours. "I thought, this is too strange," Dilbeck says. She tried to get back to sleep, but thanks to the music she could only doze off and on. When she got up at dawn, the song continued. In the months to come, Dilbeck would hear other songs. She heard merry-go-round calliopes and Silent Night. For a few weeks, it was The Star-Spangled Banner.

  • The Future Sound of Cities
    Invisible Places 18–20JULY 2014, VISEU, PORTUGAL The Future Sound of Cities Daniel Pope [email protected] Atkins, Bristol, UK Adam Lawrence [email protected] Atkins, Bristol, UK Inan Ekici [email protected] Atkins, Cambridge, UK Abstract More than half of the world’s population already live in cities and this is expected to reach 75 percent by 2050. In the developed world the effect of the growth of cities has often only been considered late in the day. This paper sets out future development scenarios for cities and urban areas, in developed and developing countries, and looks at the potential impact on soundscape. An evolving toolkit for city design is discussed. Proposals are made for great- er protection of humans, wildlife and tranquil areas and for the preservation of important “sound-marks” that identify a place. Keywords: Futures, Cities, Development, Scenario Planning, Noise, Soundscape, Acoustics. provisional version 1. Introduction The Global Health Observatory [1] has stated that as of 2010 more than 50% of the world’s population now lives in cities and predicted that this proportion will reach 75% by 2050. This paper looks out how this growth and changes within our cities may affect our soundscape and presents a toolbox of design tools to help guide the sound of cities. The burden of noise in cities affects our health and as cities grow is likely to affect great- er numbers if development continues as it has done historically. Noise has always been a problem when living in large social groups. Complaints about noise in cities are recorded as far back as Roman times.

  • Involuntary Musical Imagery, As Conditioned by Everyday Music
    Involuntary Musical Imagery, as conditioned by everyday music listening Ioanna Filippidi Submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy. Department of Music The University of Sheffield. September 2018 Abstract Music in one’s head is a very prevalent phenomenon in everyday life, but the aetiology behind it is still unclear. This thesis aimed to investigate the phenomenon of involuntary musical imagery (INMI), and particularly, under the hypothesis that it is a conditioned response from everyday music listening. Music listening can be a highly rewarding experience, and people use it more than ever to accompany their everyday lives: such systematic habits can create a process similar to classical conditioning, where, when two stimuli systematically pair, one will evoke the response that is usually elicited by the other. This premise has been investigated in three studies, designed specifically for this hypothesis: two laboratory-based behavioural experiments and an Experience Sampling (ES) study. The first experiment explored whether the conditioning process could be recreated in a laboratory context, by repeatedly pairing music with an activity. The second experiment explored the already established conditioning by investigating whether INMI would occur in the place of music: a stress induction experiment was designed to assess if individuals who use music to regulate their stress would experience INMI, in the place of music, as a coping mechanism. The third study explored INMI’s relationship to music listening in the everyday lives of individuals in order to assess this premise in a real-life setting. Overall, the findings of this research were encouraging to the hypothesis, suggesting that there is a relationship between uses of music and INMI in the aspects of activities, mood regulation, genre, and valence, and some evidence that INMI can indeed be a conditioned response.

  • Sacks Musicophilia Chapter 29.Pages
    Musicophilia: Tales of Music and the Brain by Oliver Sacks (2007) Chapter 29 Music and Identity: Dementia and Music Therapy Of the five hundred or so neurological patients at my hospital, about half have dementia of various sorts—from multiple strokes, from cerebral hypoxia, from toxic or metabolic abnormalities, from brain injuries or infections, from frontotemporal degeneration, or, most commonly, from Alzheimer’s disease. Some years ago, Donna Cohen, a colleague of mine, after studying our large population of patients with Alzheimer’s, coauthored a book called The Loss of Self. For various reasons, I deplored the title (though it is a very good book as a resource for families and caregivers) and set myself to contradicting it, lecturing here and there on “Alzheimer’s Disease and the Preservation of Self.” And yet, I am not sure that we were in real disagreement. Certainly someone with Alzheimer’s loses many of his powers or faculties as the disease advances (though this process may take many years). The loss of certain forms of memory is often an early indicator of Alzheimer’s, and this may progress to a profound amnesia. Later there may be impairment of language and, with the involvement of the frontal lobes, loss of subtler and deeper powers, like judgment, foresight, and the ability to plan. Eventually a person with Alzheimer’s may lose some fundamental aspects of self-awareness, in particular the awareness of their own incapacities. But does the loss of one’s self-awareness, or some aspects of mind, constitute loss of self? Shakespeare’s Jaques, in As You Like It, considering the seven ages of man, sees the final one as “sans everything.” Yet though one may be profoundly reduced and impaired, one is never sans everything, never a tabula rasa.
