Domain Generalization on Efficient Acoustic Scene Classification using Residual Normalization [PDF]
arXiv, 2021 It is a practical research topic how to deal with multi-device audio inputs by a single acoustic scene classification system with efficient design. In this work, we propose Residual Normalization, a novel feature normalization method that uses frequency-wise normalization % instance normalization with a shortcut path to discard unnecessary device ...

Towards Acoustic Justice [PDF]
, 2020 The essay poses acoustics as a critical and creative framework, one that gives entry onto the issues of cultural situatedness and social recognition. In particular, acoustics is underscored not only as a property of architectural space, or as a knowledge

Multi-Temporal Resolution Convolutional Neural Networks for Acoustic Scene Classification [PDF]
arXiv, 2018 In this paper we present a Deep Neural Network architecture for the task of acoustic scene classification which harnesses information from increasing temporal resolutions of Mel-Spectrogram segments. This architecture is composed of separated parallel Convolutional Neural Networks which learn spectral and temporal representations for each input ...

A Novel Temporal Attentive-Pooling based Convolutional Recurrent Architecture for Acoustic Signal Enhancement [PDF]
arXiv, 2022 In acoustic signal processing, the target signals usually carry semantic information, which is encoded in a hierarchal structure of short and long-term contexts. However, the background noise distorts these structures in a nonuniform way. The existing deep acoustic signal enhancement (ASE) architectures ignore this kind of local and global effect.

Anti-sound and Acoustical Cloaks [PDF]
Scientific Bulletin of the ''Petru Maior" University of Tîrgu Mureș, 2016 The principles by which the acoustics can be mimicked in order to reduce or cancel the vibrational field are based on anti-sound concept which can be materialized by acoustic cloaks. Geometric transformations open an elegant way towards the unconstrained

Modeling Bloch Waves in Prestressed Phononic Crystal Plates
Frontiers in Materials, 2019 The study aims at investigating the effect of a generic state of prestress on the passbands and bandgaps of a phononic crystal plate. To this end, an Updated Lagrangian scheme is developed, consisting in a two-step procedure: first, a static ...
