Performance Evaluation of Selective Fixed-filter Active Noise Control based on Different Convolutional Neural Networks
Zhengding Luo, Dongyuan Shi, Woon-Seng Gan
Due to its rapid response time and a high degree of robustness, the selective fixed-filter active noise control (SFANC) method appears to be a viable candidate for widespread use i…
Implementation of Multi-channel Active Noise Control based on Back-propagation Mechanism
Zhengding Luo, Dongyuan Shi, Junwei Ji +1
Active noise control (ANC) systems can efficiently attenuate low-frequency noises by introducing anti-noises to combine with the unwanted noises. In ANC systems, the filtered-x lea…
A Hybrid SFANC-FxNLMS Algorithm for Active Noise Control based on Deep Learning
Zhengding Luo, Dongyuan Shi, Woon-Seng Gan
The selective fixed-filter active noise control (SFANC) method selecting the best pre-trained control filters for various types of noise can achieve a fast response time. However,…
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…
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…
FRCRN: Boosting Feature Representation using Frequency Recurrence for Monaural Speech Enhancement
Shengkui Zhao, Bin Ma, Karn N. Watcharasupat +1
Convolutional recurrent networks (CRN) integrating a convolutional encoder-decoder (CED) structure and a recurrent structure have achieved promising performance for monaural speech…
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…
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…
Improving Contextual Coherence in Variational Personalized and Empathetic Dialogue Agents
Jing Yang Lee, Kong Aik Lee, Woon Seng Gan
In recent years, latent variable models, such as the Conditional Variational Auto Encoder (CVAE), have been applied to both personalized and empathetic dialogue generation. Prior w…
