The Acoustic Parameters Measurement by the Doppler Scanning Acoustic Microscope
2006Doppler continuous wave scanning acoustic microscope was developed for the investigation of the reflectance function at a frequency of 300 MHz. By testing aluminum, steel and fused quartz samples it was shown that the errors of the acoustic parameters estimation are: 9% for density, 7%, 2.5%, 1.4%- for longitudinal, shear and leaky Rayleigh waves ...

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 ...

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.

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

On the uncertainties of calculations of acoustical parameters in room acoustics measurements
2013The evaluation of room acoustics characteristics in rooms has been thoroughly described in several papers since 60-ies. Moreover, the ISO 3382 standard describes several acoustic parameters and their measurements. However, there is only a few information about the methods of pre-processing the impulse responses that are required before calculating ...
