Acoustic emission parameters and their interpretation
NDT International, 1977Abstract The need for improved methods of analysing acoustic emission signals and relating observed data to the original failure events is identified. The potential and limitations of current methods of frequency and amplitude analysis are discussed and some suggestions made.

Simulation of acoustical parameters of churches in a virtual acoustics laboratory
The Journal of the Acoustical Society of AmericaCurrent ISO standards for acoustical assessment limit the use of traditional mono-dimensional microphones for measuring equipment. However, microphone arrays offer more accurate spatial information compared to traditional microphones. This presents an opportunity to enhance research on architectural acoustics and preserve the acoustics of cultural ...

Parameter Identification of Acoustic Systems
2019There are many situations where it is desirable to estimate values of a finite set of complex parameters to describe devices and systems in acoustics. Methods for the identification of the essential parameters of dynamic systems have been pursued for numerous decades and many review articles and excellent dissertations are available on this subject [1,

Acoustical Analysis and Physiological Parameters
1987Speech is produced by complex movements of the articulators, which are known to be extremely complex structures themselves. Moreover, many articulators are not accessible for direct observation of their behavior. Some articulators can be monitored in principle, but only by means of invasive recording techniques like photoglottography or hooked wire EMG
