Soundscape in city and built environment: current developments and design potentials

City and Built Environment, Journal Year: 2023, Volume and Issue: 1(1)

Published: Jan. 12, 2023

Abstract In the field of environmental acoustics, conventional approach reducing ‘sound level’ does not always deliver required improvements in quality life. Soundscape, defined by ISO as ‘acoustic environment perceived or experienced and/or understood a person people, context’, promotes holistic approach, regarding sounds ‘resources’ rather than just ‘wastes’. The first part this review/position paper, mainly using works author and teams/collaborators examples, discusses current developments soundscape, terms soundscape understating exchanging, collecting documenting, harmonising standardising, creating designing, outreaching, showing that while considerable have been carried out, much work is still needed, basic research, more importantly, research towards practice. second paper then explores urban sound design/planning process. With proposed framework for designing open public spaces, considering four key components, including characteristics each source, acoustic effects space, social/demographic aspect users, other physical conditions, design potentials are demonstrated.

The period of home confinement during the COVID-19 pandemic made importance a high-quality surrounding environment even more evident than before. Several studies have been carried out to assess (negative) impacts noise on annoyance, particularly whilst working from (WFH). present study takes step further by (1) investigating positive and negative "actual" acoustic range activities, i.e., WFH, relaxation, physical, sexual (2) identifying characteristics an "ideal" indoor soundscape. is based qualitative analysis verbal descriptions collected open-ended questions included in survey administered January 2021 464 respondents living London, lockdown. actual scenario varied no effect task execution, disruption, distraction, concern disturbing others or being heard.

Soundscape diversity: Evaluation indices of the sound environment in urban green spaces – Effectiveness, role, and interpretation

Ecological Indicators, Journal Year: 2023, Volume and Issue: 154, P. 110725 - 110725

Published: July 28, 2023

Urban green space sound sources play an important role in providing people with high quality recreation experiences. However, the evaluation index for urban is still limited. The main purpose of this study to propose indices soundscape diversity spaces, compare acoustic diversity, and understand spaces. In our field investigation, 30 sample sites were recorded over a five-minute period, (SDI), richness (SRI), dominance (SDO), evenness (SEI) calculated. results showed that are more suitable than indices. There significant correlation between landscape patterns, there varied relationship perception different Soundscape can be explained by existing objective indicators, which explain 55% SDI model variations, 71% SRI 43% SDO 32% SEI variations. applied future planning environment design.

DMFF: Deep multimodel feature fusion for building occupancy detection

Building and Environment, Journal Year: 2024, Volume and Issue: 253, P. 111355 - 111355

Published: Feb. 27, 2024

The 2022 Global Status Report for Buildings and Construction (Buildings-GSR) indicates that construction activities have returned to pre-pandemic levels in most major economies, alongside more building energy consumption. To achieve the Net Zero emissions target by 2050, particularly post-pandemic era, accurate occupancy information is important enhance efficiency improve comfort. While remarkable progress has been made existing studies, they struggle make full use of multi-sensor data high accuracy. Furthermore, there a expectation multimodel multi-temporary fusion Transformer. In this study, we present Transformer-based multimodal, multi-temporal feature method (DMFF) detection. transfer domain knowledge from artificial intelligence into area, DMFF includes pretrain-finetune pipeline leverages pre-trained visual sound models. Multiple Transformer encoders are employed extract features different modalities. Then, propose self-attention mechanism modality learn relationships among various sensors. Our demonstrates superior performance on real dataset, outperforming machine deep learning methods (e.g., Convolutional Neural Networks, Random Forest, Multilayer Perceptrons). Applied room setting, shows promising potential savings. code demo accessible at https://github.com/kailaisun/multimodel_occupancy.
