A new approach to computer music instruments is described. Rather than sense control parameters from acoustic instruments (or non-acoustic instrument controllers), the sound of an acoustic instrument is used directly by a synthesis algorithm, usually replacing an oscillator. Parameters such as amplitude and pitch can control other aspects of the synthesis. This approach gives the player more co...

The prediction of the acoustic field evolution on a day to week frame, in a given oceanic area, is an important issue in sonar performance modeling. It relies primarily on acoustic propagation models, which convert water column and geometric/geoacoustic parameters to ‘instantaneous’ acoustic field estimates. In practice, to model the acoustic field, even the most accurate acoustic models have t...

This report provides data of the automatic acoustic synthesis of basic German vowel phoneme allophones with the use of one channel fonnant synthesizer; analyzed herein are the acoustic parameters of natural German vowels obtained from sonagrammes of sounds produced by a native speaker; provided are the data on formant characteristics of the synthesized vowel sound-types suggestive of their perc...

the quality of the communication between teachers and students and ultimately, of classroom education itself, is closely linked to the acoustic quality of the auditorium. this acoustic quality can be characterized based on the reverberation time (rt), speech transmission index (sti) and the sound insulation. in this context, an acoustic study was conducted in an auditorium located in the higher...

The purpose of this study was to evaluate quantitatively the parameters of the video laryngostroboscopy (VLS) and determine correlations between the VLS parameters and acoustic vocal function parameters. Digital VLS recordings, acoustic voice assessment, calculation of dysphonia severity index (DSI) and registration of voice range profile (VRP) were performed for 206 individuals: 50 healthy and...

This paper presents a two-stage procedure, based on the Fisher criterion and automatic classi cation trees, for designing acoustic parameters (APs) that target phonetic features in the speech signal. This procedure and a subset of the TIMIT training set were used to develop acoustic parameters for the phonetic features: sonorant, syllabic, strident, palatal, alveolar, labial and velar. Results ...

We present an acoustic rendering approach visualizing the listener-specific contribution of frequency-dependent pressure fields on a scene geometry with acoustic reflection and scattering properties. Our method facilitates the evaluation of simulated acoustics showing the effect of simulation parameters like absorption and scattering. The image-based spatial localization of acoustic properties ...
