Do neonates hear what we measure? Assessing neonatal ward soundscapes at the neonates ears
Bhan Lam, Peijin Esther Monica Fan, Yih Yann Tay +5
Acoustic guidelines for neonatal intensive care units (NICUs) aim to protect vulnerable neonates from noise-induced physiological harm. However, the lack of recognised internationa…
Extracting Urban Sound Information for Residential Areas in Smart Cities Using an End-to-End IoT System
Ee-Leng Tan, Furi Andi Karnapi, Linus Junjia Ng +2
With rapid urbanization comes the increase of community, construction, and transportation noise in residential areas. The conventional approach of solely relying on sound pressure…
Automating Urban Soundscape Enhancements with AI: In-situ Assessment of Quality and Restorativeness in Traffic-Exposed Residential Areas
Bhan Lam, Zhen-Ting Ong, Kenneth Ooi +10
Formalized in ISO 12913, the "soundscape" approach is a paradigmatic shift towards perception-based urban sound management, aiming to alleviate the substantial socioeconomic costs…
Preliminary investigation of the short-term in situ performance of an automatic masker selection system
Bhan Lam, Zhen-Ting Ong, Kenneth Ooi +4
Soundscape augmentation or "masking" introduces wanted sounds into the acoustic environment to improve acoustic comfort. Usually, the masker selection and playback strategies are e…
Anti-noise window: Subjective perception of active noise reduction and effect of informational masking
Bhan Lam, Kelvin Chee Quan Lim, Kenneth Ooi +3
Reviving natural ventilation (NV) for urban sustainability presents challenges for indoor acoustic comfort. Active control and interference-based noise mitigation strategies, such…
Crossing the Linguistic Causeway: Ethnonational Differences on Soundscape Attributes in Bahasa Melayu
Bhan Lam, Julia Chieng, Kenneth Ooi +4
Despite being neighbouring countries and sharing the language of Bahasa Melayu (ISO 639-3:ZSM), cultural and language education policy differences between Singapore and Malaysia le…
Autonomous Soundscape Augmentation with Multimodal Fusion of Visual and Participant-linked Inputs
Kenneth Ooi, Karn N. Watcharasupat, Bhan Lam +2
Autonomous soundscape augmentation systems typically use trained models to pick optimal maskers to effect a desired perceptual change. While acoustic information is paramount to su…
Assessment of a cost-effective headphone calibration procedure for soundscape evaluations
Bhan Lam, Kenneth Ooi, Zhen-Ting Ong +3
To increase the availability and adoption of the soundscape standard, a low-cost calibration procedure for reproduction of audio stimuli over headphones was proposed as part of the…
Do uHear? Validation of uHear App for Preliminary Screening of Hearing Ability in Soundscape Studies
Zhen-Ting Ong, Bhan Lam, Kenneth Ooi +3
Studies involving soundscape perception often exclude participants with hearing loss to prevent impaired perception from affecting experimental results. Participants are typically…
ARAUS: A Large-Scale Dataset and Baseline Models of Affective Responses to Augmented Urban Soundscapes
Kenneth Ooi, Zhen-Ting Ong, Karn N. Watcharasupat +3
Choosing optimal maskers for existing soundscapes to effect a desired perceptual change via soundscape augmentation is non-trivial due to extensive varieties of maskers and a deart…
Singapore Soundscape Site Selection Survey (S5): Identification of Characteristic Soundscapes of Singapore via Weighted k-means Clustering
Kenneth Ooi, Bhan Lam, Joo Young Hong +3
The ecological validity of soundscape studies usually rests on a choice of soundscapes that are representative of the perceptual space under investigation. For example, a soundscap…
Crossing the Linguistic Causeway: A Binational Approach for Translating Soundscape Attributes to Bahasa Melayu
Bhan Lam, Julia Chieng, Karn N. Watcharasupat +4
Translation of perceptual descriptors such as the perceived affective quality attributes in the soundscape standard (ISO/TS 12913-2:2018) is an inherently intricate task, especiall…
Preliminary assessment of a cost-effective headphone calibration procedure for soundscape evaluations
Bhan Lam, Kenneth Ooi, Karn N. Watcharasupat +4
The introduction of ISO 12913-2:2018 has provided a framework for standardized data collection and reporting procedures for soundscape practitioners. A strong emphasis was placed o…
Deployment of an IoT System for Adaptive In-Situ Soundscape Augmentation
Trevor Wong, Karn N. Watcharasupat, Bhan Lam +4
Soundscape augmentation is an emerging approach for noise mitigation by introducing additional sounds known as "maskers" to increase acoustic comfort. Traditionally, the choice of…
Autonomous In-Situ Soundscape Augmentation via Joint Selection of Masker and Gain
Karn N. Watcharasupat, Kenneth Ooi, Bhan Lam +3
The selection of maskers and playback gain levels in a soundscape augmentation system is crucial to its effectiveness in improving the overall acoustic comfort of a given environme…
Quantitative Evaluation Approach for Translation of Perceptual Soundscape Attributes: Initial Application to the Thai Language
Karn N. Watcharasupat, Sureenate Jaratjarungkiat, Bhan Lam +8
Translation of perceptual soundscape attributes from one language to another remains a challenging task that requires a high degree of fidelity in both psychoacoustic and psycholin…
