This paper introduces a novel portable and scalable Active Noise Mitigation (PSANM) system designed to reduce low-frequency noise from construction machinery. The PSANM system cons…
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…
Active Noise Control based on the Momentum Multichannel Normalized Filtered-x Least Mean Square Algorithm
Dongyuan Shi, Woon-Seng Gan, Bhan Lam +2
Multichannel active noise control (MCANC) is widely utilized to achieve significant noise cancellation area in the complicated acoustic field. Meanwhile, the filter-x least mean sq…
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…
Active Noise Control in The New Century: The Role and Prospect of Signal Processing
Dongyuan Shi, Bhan Lam, Woon-Seng Gan +2
Since Paul Leug's 1933 patent application for a system for the active control of sound, the field of active noise control (ANC) has not flourished until the advent of digital signa…
MOV-Modified-FxLMS algorithm with Variable Penalty Factor in a Practical Power Output Constrained Active Control System
Chung Kwan Lai, Dongyuan Shi, Bhan Lam +1
Practical Active Noise Control (ANC) systems typically require a restriction in their maximum output power, to prevent overdriving the loudspeaker and causing system instability. R…
Real-time modelling of observation filter in the Remote Microphone Technique for an Active Noise Control application
Chung Kwan Lai, Bhan Lam, Dongyuan Shi +1
The remote microphone technique (RMT) is often used in active noise control (ANC) applications to overcome design constraints in microphone placements by estimating the acoustic pr…
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
