Physiological Measures Regress onto Acoustic and Perceptual Features of Soundscapes

2013

There is no exact model for the relationship between the autonomic nervous system (ANS) and evoked or perceived emotion. Music has long been a privileged field for exploration, while the contribution of soundscape research is more recent. It is known that health is influenced by the sonic environment, and the study here presented aimed to investigate the nature and strength of relationships between soundscape features and physiological responses linked to relaxation or stress. In a controlled experiment, seventeen healthy volun-teers moved freely inside a physical installation listening to soundscape recordings of nature, urban parks, eateries, and shops, reproduced using 3D ambisonic techn…

Soundscape design through evolutionary engines

2008

Abstract Two implementations of an Evolutionary Sound Synthesis method using the Interaural Time Difference (ITD) and psychoacoustic descriptors are presented here as a way to develop criteria for fitness evaluation. We also explore a relationship between adaptive sound evolution and three soundscape characteristics: keysounds, key-signals and sound-marks. Sonic Localization Field is defined using a sound attenuation factor and ITD azimuth angle, respectively (Ii, Li). These pairs are used to build Spatial Sound Genotypes (SSG) and they are extracted from a waveform population set. An explanation on how our model was initially written in MATLAB is followed by a recent Pure Data (Pd) impleme…

Numerical methods for a nonlinear impact model: A comparative study with closed-form corrections

2011

A physically based impact model-already known and exploited in the field of sound synthesis-is studied using both analytical tools and numerical simulations. It is shown that the Hamiltonian of a physical system composed of a mass impacting on a wall can be expressed analytically as a function of the mass velocity during contact. Moreover, an efficient and accurate approximation for the mass outbound velocity is presented, which allows to estimate the Hamiltonian at the end of the contact. Analytical results are then compared to numerical simulations obtained by discretizing the system with several numerical methods. It is shown that, for some regions of the parameter space, the trajectorie…

Musica a Palermo al tempo dei Chiaromonte: il Liber continens capitula per totum annum (ms. 8) e il Cantus diversi ad usum Panormitanae Ecclesiae (ms…

2020

Dopo aver delineato un quadro generale della musica a Palermo nel Trecento, il contributo si incentra su due codici conservati presso l'Archivio Storico Diocesano di Palermo: il "Liber continens capitula per totum annum" e il "Cantus diversi ad usum Panormitanae Ecclesiae". Dei due codici si esplicitano alcune caratteristiche degne di interesse, in particolare la presenza nel primo dell’antifona "Salve regina" tropata, e nel secondo della sequenza "Victimae paschali laudes" con varianti testuali che permettono di cogliere alcune specificità della tradizione liturgico-musicale siciliana.

When Soundscape Studies Encounter Buddhism : Methodology Development of Soundscape Studies conducted at Chinese Buddhist Temples

2012

The ethnographic ideals of ‘reflectiveness’ and ‘openness’ inspire the researcher to think deeply about how to develop ethnographic soundscape methodology during the research process. This Paper focuses on developing adaptive research methods for soundscape studies on Chinese Buddhist temples. Chinese Buddhist temples are monasteries and dwelling places of monks. They are also the miniature of “pure land”. Temples have been considered as the landmarks of quiet and peace in China for thousands of years. What and how are the soundscapes of Buddhist temples? Have any changes happened in the soundscapes? How does the Buddhist way of thinking about hearing impact the Buddhists’ way of hearing? W…
