Linking atmospheric and urban auralization models

Acta Acustica, 2022
In a recent publication, we presented an efficient method to find eigenrays in a stratified, moving medium. The simulation framework is designed to auralize aircraft flyovers. However, the method is restricted to the direct sound and a ground reflection.

Perceptual thresholds for the effects of room modes as a function of modal decay [PDF]

, 2015
Room modes cause audible artefacts in listening environments. Modal control approaches have emerged in scientific literature over the years and, often, their performance is measured by criteria that may be perceptually unfounded.

The KW-boundary hybrid digital waveguide mesh for room acoustics applications [PDF]

, 2007
The digital waveguide mesh is a discrete-time simulation used to model acoustic wave propagation through a bounded medium. It can be applied to the simulation of the acoustics of rooms through the generation of impulse responses suitable for auralization

A study on the auralization system using flexible rendering for virtual reality-based acoustic simulation

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2019
It is not easy for architects to consider the effect of the acoustic environment of a plan in the early design phase because it requires great expertise to properly use acoustic simulation software.

Auralization of electric vehicles for the perceptual evaluation of acoustic vehicle alerting systems

Acta Acustica
Electric vehicles (EVs) typically emit little noise at low driving speeds, which increases the risk of accidents for vulnerable road users such as pedestrians.

Auralization of Amplitude Modulated Helicopter Flyover Noise [PDF]

Rotorcraft noise is an active field of study as the sound produced by these vehicles is often found to be annoying. A means to auralize rotorcraft flyover noise is sought to help understand the factors leading to annoyance.

Interpolation of scheduled simulation results for real-time auralization of moving sources

Acta Acustica
A central part of auralization is the consideration of realistic sound propagation effects. This can be achieved using computationally efficient physics-based simulations based on the principle geometrical acoustics. When considering complex effects, e.g.

Promoting Treg Polarization‐Mediated Anti‐Scar and Appendage Regeneration in Wound Healing

Advanced Science, EarlyView.
This study develops a PLGA@LA‐BMP4‐PG bilayer scaffold to address scar formation and appendage loss in skin repair. The piezoelectric PLA layer enhances cell migration via electric fields, while GelMA delivers LA promoting Tregs polarization and BMP4 inhibiting FBs differentiation.

Virtual Acoustics

Archives of Acoustics, 2014
Virtual Reality (VR) systems are used in engineering, architecture, design and in applications of biomedical research. The component of acoustics in such VR systems enables the creation of audio-visual stimuli for applications in room acoustics, building
