Acoustic simulations of Mudejar-Gothic churches

Journal of the Acoustical Society of America, 2009
In this paper, an iterative process is used in order to estimate the values of absorption coefficients of those materials of which little is known in the literature, so that an acoustic simulation can be carried out in Mudejar-Gothic churches. The estimation of the scattering coefficients, which is even less developed, is based on the size of the ...

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 ...
