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.

An interdisciplinary sound classification framework for environmental sound design

Abstract ID: 1761
One of the objectives of architectural design is to create multi-sensory environments. The users are under the influence of a wide variety and intense perceptual data flow when users experience a designed space. Architects and environmental designers should not ignore the sense of hearing, one of the most important of the five primitive senses that allow us to experience the physical environment within the framework of creative thinking from the first stage of the design process. Today, auditory analysis of spaces has been studied under architectural acoustics, soundscapes, multi-sensory interactions, and sense of place. However, the current sound design methods implemented in the film and video game industries and industrial design have not been used in architectural design practices. Sound design is the art and application of making soundtracks in various disciplines and it involves recognizing, acquiring, or developing of auditory components. This research aims to establish a holistic architectural sound design framework based on the previous sound classification and taxonomic models found in the literature. The proposed sound design framework will help the architects and environmental designers classify the sound elements in the built environment and provide holistic environmental sound design guidelines depending on the spaces' functions and context.

A research on assessment of soundscape in urban area by means of Caption Evaluation Method: effects of context on evaluation of soundscape

Abstract ID: 2755
Caption Evaluation Method is a technique that was developed in Japan to learn about the reason of evaluation of landscape. The investigative method is a formalized one and can show the element of landscape that a person focused on when he made an evaluation of the landscape, and the reason why he made a good or bad evaluation on it. In the present research, Caption Evaluation Method is applied to the survey of soundscape in urban area. Twenty-one subjects were instructed to walk along the predetermined route, and to take a picture and make evaluation of soundscape when they found out sound that attracted their attention. They rated the sound as good, bad or normal, and they reported the character and impression of it by formalized questionnaire. As a result, one hundred fifty-seven sound elements were obtained. They were classified under the proposed way in the previous research. Results show that traffic noise is assessed bad by almost all the people because of its noisy character, but sound from information display system receives different assessment among people. It is supposed that evaluation of not so noisy sound can be easily affected by the context in a persons mind.

Physiological and psychological responses to soundscapes and their connections using machine learning
Time: 8:40 am
Author: Ming Yang
Abstract ID: 2891
Acoustic environment has significant impacts on humans feelings and emotions, cognitive performance, and behaviours. It evokes both physiological and psychological responses, which in the long term affect physical and mental health. It has been long believed that physiological and psychological responses are interconnected, yet their correlations are complex and may vary among conditions and studies. This present research study explores the physiological and psychological responses at the exposure to acoustic environment in a short period of time, and examines whether the physiological responses are able to predict the psychological responses. In this research, the physiological and psychological responses of subjects to a set of soundscapes are collected in a laboratory setting, by respectively continuous physiological measurements and self-report ratings on subjective experiences. The connections between the physiological and psychological responses are examined using machine learning methods. The results show the connections between physiological and psychological responses to soundscape. To a certain degree, it is able to predict the psychological responses from the measured physiological responses.

Soundscape assessment of non-acoustic factors for effective stakeholder engagement in airport expansion projects in the UK
Time: 8:00 am
Author: Lisa Lavia
Abstract ID: 2976
Effective soundscape planning, in accordance with the ISO soundscape standard series, is predicated on accurately assessing the human response to sound in context. ccurately assess the human response for this purpose requires the identification of context specific non-acoustic factors (NAFs). In particular, the NAF of stakeholders perceived control over sound from developments directly impacts the effectiveness of engagement in planning processes. However, what constitutes perceived control can vary widely, including stakeholders' experiences, perceptions and requirements in context. Perceived control affect quality of life and therefore it is a factor in sustainable planning and development processes. This primarily qualitative constructivist grounded theory study investigates the NAFs comprising stakeholders perceived control and the impact on effective engagement in the context of planning and soundscape management for airport expansion projects in the UK. The initial stages of this research included participant observation and 1:1 interviews. Preliminary findings indicate context specific discrete aspects regarding communication quality (as distinct from quantity) as intrinsic to developing, supporting and maintaining perceived control amongst stakeholders. This research builds on existing soundscape and noise and health findings to develop a conceptual framework for effective stakeholder engagement for standardised soundscape design and planning in the built environment.
