Soundscape in the Project Activity of Schoolchildren in the Context of Electronic Music Creativity [PDF]

open access: yesМузыкальное искусство и образование, 2021
Soundscape is a multidimensional concept that means both a corpus of environmental sounds, which is claimed by a significant range of sciences, and a musical genre that is widely used in the creative practices of contemporary art. There is a method of

Estimating the parameters of the seabed using the spatial characteristics of ocean ambient noise [PDF]

open access: yesMATEC Web of Conferences, 2019
When solving traditional underwater problems, the boundary condition is always used to calculate the sound field. In practice, however, it is hard to get the boundary conditions of the seabed. So geoacoustics inversion is needed to acquire the parameters

The Importance of Reverberation for the Design of Neonatal Incubators

open access: yesFrontiers in Pediatrics, 2021
Low frequency noises are predominant in neonatal intensive care units (NICUs). Some studies affirm that neonates can perceive noises from 113 Hz, and can therefore be affected by sound sources with high spectral content at low frequencies (e.g ...

Neural network-based selective noise control with sound source separation

open access: yesNihon Kikai Gakkai ronbunshu, 2023
In noisy environments such as factories or construction sites, noise should be reduced and the speech of workers moving in the environments should be recognized.

Analysis of the Effects and Causes of Driver Horn Use on the Acoustic Environment at Urban Intersections in Taiwan

open access: yesApplied Sciences, 2022
Car horns were originally installed in vehicles for safety. However, many urban areas in several countries face noise problems related to the use of car and motorbike horns. To propose measures to suppress the use of horns, relationships between horn use

A multi-task neural network for source localization in shallow-water environment with depth classification [PDF]

open access: yesJASA Express Letters
Limited high-quality training data can cause overfitting and weak generalization in deep-learning-based source localization, leading to degraded performance in realistic environments. In this study, a multi-task neural network with a depth-classification
