Supplying sufficient early reflections to audience members is an important prerequisite to good acoustic quality in performing arts spaces. However, the relationship between the geometry of a room and its acoustic efficiency in terms of early energy has rarely been investigated using basic geometrical principles. The present study demonstrates the possibility of predicting the average value of ...

The quality of optoacoustic tomographic reconstructions can be severely affected by acoustic reflections or scattering arising at interfaces of highly mismatched organs, such as bones, lungs, or other air-containing cavities. We present a procedure to reduce the associated artefacts based on estimation of the acoustic scatterers distribution within the imaged object. Signals generated by a stro...

Cochlear implant systems translate acoustic information sampled from the acoustic environment into electrical impulses delivered directly to the patient’s auditory nervous system in an attempt to recreate functional hearing. After more than 30 years of intensive development, the efficacy of cochlear implants for the rehabilitation of severe to profound hearing loss has been well established, wi...

The paper analyzes the prosody features, which includes the intonation, speaking rate, intensity, based on classified emotional speech. As an important feature of voice quality, voice source are also deduced for analysis. With the analysis results above, the paper creates both a CART model and a weight decay neural network model to find acoustic importance towards the emotional speech classific...

Foreign accent has been assumed to be closely related to the degree of articulatory, acoustic and perceptual similarity between L1 and L2 sounds. This study examined cross-language acoustic and perceptual similarities between Korean and English sibilant fricatives: Korean [−tense] /s/ and [+tense] /s*/ vs. English alveolar /s/ and palato-alveolar /ʃ/. To determine acoustic similarity, two param...

The ways of increasing the reliability and service life industrial facilities are considered. types hardening technologies methods their control analyzed. An approach that makes it possible to evaluate quality based on registration acoustic emission (AE) is described. results experimental research three strengthening presented effectiveness proposed shown. obtained can be used assess at real in...
