Foetal Acoustic Simulator

2019 11th International Conference on Communication Systems & Networks (COMSNETS), 2019
Foetal phonocardiography is the passive recording of foetal heart sounds. It is a valuable alternative to existing expensive technologies like foetal electrocardiography, cardiotochography etc. for ensuring the wellbeing of the foetus. To test and validate foetal heart monitoring system based on phonocardiography, a foetal acoustic simulator model was ...

Acoustic Simulations of Combined Electric and Acoustic Hearing (EAS)

Ear and Hearing, 2005
Our aim was to explore the consequences for speech understanding of leaving a gap in frequency between a region of acoustic hearing and a region stimulated electrically. Our studies were conducted with normal-hearing listeners, using an acoustic simulation of combined electric and acoustic (EAS) stimulation.Simulations of EAS were created by low-pass ...

Simulating an acoustic recognizer

ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
In this paper we describe a speech recognition simulator whose input is phonemic transcriptions and which produces scores that simulate the scores generated by a real acoustic recognizer. We used a phonemic distance metric to approximate acoustic distances. A dynamic programming algorithm was used to find the optimum match between phoneme strings based

Simulating acoustic waves in acoustic black hole analogues

The Journal of the Acoustical Society of America, 2022
We present a physical model and a numerical method to simulate nonlinear acoustic waves emitted from moving boundaries in a moving background flow field with transition from subsonic to supersonic flow speeds. The physical model is based on a convective form of the Westervelt equation and accounts for the motion of the background medium and the ...

Web-based geometric acoustic simulator

Proceedings of the 23rd International ACM Conference on 3D Web Technology, 2018
Geometric acoustics is one of the most commonly used techniques for exploring what a virtual environment sounds like. These methods allow the user to place a sound source and receiver in a space and compute how the space influences what the receiver hears. These simulation methods are well-known, but most are proprietary or difficult to implement.
