15.04 Soundscape Preservation

Soundscape composition analysis combined with acoustics and musicology: a case study on the music piece of Daybreaking

Abstract ID: 1654

With its own unique musical vocabulary oundscape composition has been unprecedently developed all over the world. The analysis of music s from the perspective of acoustics has its own advantages that cannot be replaced by the traditional musicology. Based on  music  named Dayb for a hope to overcome COVID-19, this paper analyzes the acoustic elements of , frequency spectrum and waveform. Combined with the traditional musicology, it can show that the undulation of waveform has associated with the formal structure and the visualization of music. The frequency spectrum shows that as the climax of the piece, the sound has a high energy in the range of 300-1000Hz, which is one of the extremely sensitive frequency ranges for human. The composer not only skillfully integrates the chanting of monks with the complex environmental sounds, but also reflects the innovative composition skills. The change of  from weak to strong or contrarily is also in line with the emotional expression, that is, the core idea of moving from nature to nature. Since soundscape c retains more information, it is easier to immerse the audience in the listening process and appreciate the beautiful hope rather than the difficulty of understanding it.

Vibroacoustics in Science and Music
Time: 8:00 pm

Abstract ID: 3020

In 2001 the band Cornucopia  (Puerto Rican musicians Jorge Castro and Claudio Chea) released an album called “Vibroacústica”. The title refers to a disease that allegedly afflicts people who have been exposed to loud noise over long periods of time. The vibrations thicken the walls of the heart, so the theory goes, and damage the immune, gastrointestinal, and neurological systems. This is noise as toxin, entering and sickening the body. The album takes the disease as its point of departure, and using location recordings of the coast of Puerto Rico, analog synthetic manipulations and digital processing, both recreates and protests the noise and its impact on human beings in Vieques, Puerto Rico, which was the target of bombing practice for over sixty years. This paper argues that the album subverts the idea of the preservation of a soundscape and instead reinterprets the sonic violence of occupation with the tweets, chirps and burbles of its soundtracks.

Relational analysis in soundscape preservation
Time: 6:40 am

Abstract ID: 3120

Given the musical origins of soundscape studies, soundscape preservation might suggest the need to protect specific features—such as prominent soundmarks or long-standing natural sounds—to maintain a sonic environment’s composition. However, the identification of a soundscape primarily by its discrete elements misses the importance of relational longevity. A relational lens of identification can distinguish a soundscape’s effects on visitors rather than simply the presence of specific components, placing human perception candidly at the center of consideration. For instance, an urban courtyard might no longer echo with hand-drawn carts from the street, yet visitors continue to experience a distanced connection with evolving traffic sounds – here the sonic-spatial relationship persists rather than sonic elements being frozen in time. This paper will discuss longevity in the relationships connecting use, architectural space, and sonic character. The discussion draws from architectural analysis, soundwalking, and psychoacoustic research in exploring soundscape preservation within the orbit of heritage conservation more broadly. Case studies focus on a variety of historic contexts, including a military installation, medieval church, and factory landscape, highlighting the limitations of a compositional soundscape reading, the fundamental role of transit through a soundscape for visitors, and the potentials for relational analysis in soundscape preservation efforts.
