- A structured approach to voice range profile (phonetogram) analysis. Sulter, Arend M.; Wit, Hero P. // Journal of Speech & Hearing Research;Oct94, Vol. 37 Issue 5, p1076
Focuses on phonetogram, a structured approach to voice range profile analysis. Structured analysis based on quantitatively determining the shape, area and `Speaking range' dynamics; Calculation of the parameter sets that describes the features; Establishing normative data for specified groups.
- Simulation and Synthesis of Elastic Wave Absorbers at the Boundary of a Rigid Body: Incidence of Longitudinal Waves. Tyutekin, V. V. // Acoustical Physics;Jul2001, Vol. 47 Issue 4, p461
Results of a computer simulation of an impedance absorber for longitudinal plane elastic waves incident on a free boundary of a rigid body are presented. The absorbing elements are mechanical resonators (of the elasticity-mass type) with two degrees of freedom and, hence, with two resonance...
- SWR by any other name... Kinley, Harold // Mobile Radio Technology;Feb98, Vol. 16 Issue 2, p8
Discusses various aspects of standing wave ratio (SWR), an indication of the degree of match, or mismatch, of load impedance to source impedance. Effects of line loss; Reflection coefficient; Method of converting forward and reflected power measurements into an equivalent SWR figure.
- Acoustic barriers based on periodic arrays of scatterers. Sanchez-Perez, Juan V.; Rubio, Constanza; Martinez-Sala, Rosa; Sanchez-Grandia, Rafael; Gomez, Vicente // Applied Physics Letters;12/30/2002, Vol. 81 Issue 27, p5240
It is well known that certain periodic structures built by repetition of elements produce sound attenuation effects as a consequence of the destructive interference of the scattered waves by these elements. The sound attenuation results that we got from transmission experiments with these kind...
- static acoustic impedance. // Taber's Cyclopedic Medical Dictionary (2009);2009, Issue 21, p2197
A definition of the term "static acoustic impedance," which refers to the opposition to the passage of sound through the external auditory canal, is presented.
- Acoustic Characteristics of a Multichannel Transmission Line of Longitudinal—Flexural Type. Tyutekin, V. V. // Acoustical Physics;Jan2003, Vol. 49 Issue 1, p91
The properties of a multichannel transmission line of longitudinal-flexural type are considered. Analytical formulas are obtained for the principal acoustic characteristics of a symmetric multichannel transmission line, such as the input impedance matrix and the vectors of the reflection and...
- Correlation between bubble repulsion and metal properties. Sekak, Khairunnadim Ahmad; Bidin, Noriah // AIP Conference Proceedings;2000, Vol. 524 Issue 1, p407
One way to protect a parent metal from cavitation impact is by rejecting the bubble from the solid boundary. The repulsion of a bubble can be achieved by employing a low impedance material as a coating. We have carried out an experimental study by coupling the low impedance material with...
- Determination of the conditional association constants from the sound velocity data in binary liquid mixtures. Glinski, Jacek // Journal of Chemical Physics;2/1/2003, Vol. 118 Issue 5, p2301
Two models of calculating the association constants in mixtures of two weakly interacting liquids are proposed and analyzed: one of them assumes additivity of acoustic impedance with the molar fractions of components, and the other assumes additivity of the time of transmission of the acoustic...
- Essential role of impedance in the formation of acoustic band gaps. Kee, Chul-Sik; Kim, Jae-Eun // Journal of Applied Physics;2/15/2000, Vol. 87 Issue 4, p1593
Presents a study which investigated the role of impedance in the formation of acoustic band gaps (ABG). Applications of ABG; Methodology used in the study; Results.
