15.03 Soundscapes in Urban Planning and Architecture

An interdisciplinary sound classification framework for environmental sound design
Time: 12:00 pm

Author: Kivanc Kitapci

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.

Basic study on the methods of noise countermeasures for safeguard-ing intangible cultural properties such as Japanese festivals
Time: 11:00 am

Author: Mari Ueda

Abstract ID: 2651

In the Ogino area of ??Atsugi City, where the Kanagawa Institute of Technology is located, Japanese drums are being practiced and the arts are inherited in order to perform at events such as Japanese festivals. It may be reported. Therefore, in Atsugi City, when the main purpose is to practice Japanese drums, the practice place is restricted, such as not being able to obtain permission to use the facilities of the city. In order to solve such a problem, we performed acoustic measurement of Japanese drums and clarified their acoustic characteristics. It was confirmed that the sound near the drum due to the repellent impact of the Nagado daiko has a lot of energy even in the low frequency component of 200 Hz or less, and the magnitude of the radiated sound SEL increases as the sound is hit harder. It is also difficult for local governments to take physical noise countermeasures for membranophones from a cost perspective. Therefore, the ultimate goal of this research was to obtain a solution to the noise problem by social measures to continue the succession activities of traditional musical instruments such as Japanese drums, which are difficult to take measures against physical noise. Launched and operated a website to understand the current state of noise complaints and to collect the voices of local residents regarding the sound of drums according to the lifestyle and situation of each individual as part of the Noise Compatibility Planning attempt. We built the system.

The relevance of psychoacoustic percentiles for the description of morphological characteristics in urban areas
Time: 11:40 am

Author: Daniel de la Prida

Abstract ID: 2789

Research over the last decade has explored the relevance of psychoacoustic indicators such as Loudness (N), Sharpness (S), Roughness (R) and Fluctuation Strength (FS) for the description of the perceptual construct of soundscapes. Furthermore, the recent ISO 12913-2 standard, published in 2018, recommends their use for the quantitative assessment of soundscapes. However, usually, investigations on soundscapes are using averages of the psychoacoustic indicators, and little research has evaluated the relevance of percentiles for the perceptual description of physical environments in terms of geometrical features, prevailing noise sources, temporal and meteorological variables, etc. This study aims to verify whether psychoacoustic percentiles can representatively describe the geometrical features of different urban sonic environments. For this purpose, recordings were taken in Aachen and Madrid in different days and seasons, at 14 certain locations in each town. In addition, morphological data was collected of the sites. A Principal Component Analysis (PCA), conducted on psychoacoustic percentiles (i.e., P1, P5, P10, P50, P90, P95, P99) of N, S, R and FS and geometrical features (road, pedestrian sidewalk and propagation path widths, as well as building heights), showed well-defined components, highlighting the fact that some percentiles can describe specific geometrical features of the urban sonic environments.

Influence of soundscape on emotional arousal in monumental open spaces in China
Time: 11:20 am

Author: Wei Zhao

Abstract ID: 2998

As a type of landscape with special cultural connotation and symbolic significance, commemorative places carry people's emotional sustenance for the memorial subject. Based on the special cultural and spiritual connotation of commemorative landscape, it is different from other landscape types in terms of soundscape perception. This paper takes Nanjing Sun Yat-sen Mausoleum and the square in front of Yuhuatai Martyrs Cemetery as examples to conduct a comparative study. Through field questionnaire surveys, data such as basic information, environmental evaluation, and emotional arousal evaluation of subjects are obtained. The results show that (1) the matching degree of the audiovisual landscape affects the acoustic environment satisfaction and environmental satisfaction, and shows a positive correlation. (2) The sound environment evaluation such as the sense of ritual and solemnity is positively correlated with the satisfaction of the soundscape. (3) The degree of arousal of voice and emotion is positively correlated with the sense of ritual, solemnity, mission, responsibility, admiration, and meaning. Researching the soundscape perception of commemorative places from the perspective of emotional arousal will help build a soundscape environment with a more memorable atmosphere, arouse individual emotions, and achieve better memorial and educational significance, so as to expand the related research of soundscape.

Relationships between soundscape and landscape evaluation at a historical block in the Central Street in Harbin of China
Time: 8:40 pm

Author: Qingxuan Rui

Abstract ID: 3150

Historical blocks are important material and cultural heritages in the city, and the inheritance of urban culture is affected by its acoustic environment. This article selects Central Street as the research object to study the relationship between its acoustic environment perception and landscape evaluation. The method of field investigation combined with questionnaire survey was adopted. The results show that the pleasure and richness of the soundscape have a positive impact on the satisfaction of the landscape. Under a certain sound intensity, music and broadcast sounds can increase the pleasure of the soundscape, but at excessively high sound intensity, it reduces the pleasure of the soundscape; traffic sounds and construction sounds have a negative impact on the pleasure of the soundscape . At the same time, the elderly have a higher evaluation of the soundscape and landscape perception. This research can be used in the soundscape construction of historic districts and provide a certain reference value for the subsequent renovation and reconstruction of historic districts and improving their integrity.

An initiation to revive the unique sound of Indonesian cities
Time: 8:00 pm

Author: Christina Eviutami Mediastika

Abstract ID: 3261

As a large country with thousands of ethnic groups and cultures, it is hoped that every city in Indonesia will have its uniqueness. However, preliminary data collected from 10 major cities in Indonesia shows no uniqueness. The most visited public places in these cities, i.e. parks and squares, which are generally associated with natural sounds, are dominated by human and traffic noise. Surprisingly, a noisy acoustic environment is not considered a nuisance. The study reported here looks for reasons why people ignore the noise. An online questionnaire developed using a 5-point Likert scale was distributed to collect data due to the Covid-19 pandemic. Five hundred and ninety-five respondents participated in the survey. ANOVA and Kruskal Wallis test were run to identify differences between soundscape dimensions and differences in soundscape attribute ratings, respectively. The data shows that Indonesians visit public places for communal or social activities, which are triggered by the attractiveness of the places and the types of activities they can participate in. It is the reason why noise is not considered a nuisance. Pleasantness and eventfulness are the two dominant soundscape dimensions found in this study. In the Indonesian context, pleasure correlates with events. Eventfulness is associated with the number of people and their activities in public places. However, in most of the cities surveyed, eventfulness scores were low when they were unable to engage in the events held in public places. They visit public places based on the attractiveness of the place and the activities, and they feel comfortable in noisy public places when they can be involved in the activity. Once people become attached to communal activities in public places, the pleasantness dimension also exists. Thus, two things need to be considered to improve the acoustic environment of cities in Indonesia. First is by reducing traffic noise to increase the dimensions of eventfulness by using attractive attractions in public places. Second is to investigate the types of attractions that are of interest, if possible, is to restore local culture with its unique sound to build a unique city soundscape. In this study, participants identified the uniqueness of sounds in public places by using sounds that could not be classified as unique such as the voice of and the music played by street vendors.
