Physical and acoustical properties of zooplankton
The Journal of the Acoustical Society of America, 1982The target strengths of marine zooplankton are often predicted from fluid sphere scattering models. These models require estimation of certain physical properties of the individual zooplankters: radius of the equivalent sphere, mass density, and either sound speed or compressibility.

Acoustic emission properties of callus
Medical & Biological Engineering & Computing, 198111 New Zealand white rabbits with 45 degree midshaft oblique osteotomies were stressed in shear while monitoring acoustic emission events. The ringdown counting method demonstrated a reasonably reproducible pattern when counting events against load; that is, each fracture remained essentially quiet until over 50% of load to failure had been applied ...

Acoustic Properties of the Nasal Tract
Phonetica, 1976Abstract Sweep frequency measurements of the transfer function of nasals and nasalized vowels have been found to show a more complex pole-zero pattern than can be predicted with a traditional model of the nasal tract which consists of two parallel tubes coupled to the oral cavities.

Properties of Acoustic Reflex Adaptation
Annals of Otology, Rhinology & Laryngology, 1977The dynamic behavior of the acoustic reflex to continuous sinusoidal stimuli was investigated. The major purpose was to determine the temporal characteristics of reflex adaptation as frequency (0.5, 1.0, 2.0, 3.0, 4.0 kHz) and suprathreshold level (6, +12, +18 dB re reflex threshold) were systematically varied.

Acoustic properties of gallium selenide
Physical Review B, 1995We investigate the effect of illumination on the velocity of the ${\mathit{L}}_{\mathrm{\ensuremath{\perp}}}$ and ${\mathrm{FT}}_{\mathrm{\ensuremath{\perp}}}$ acoustic-wave propagation along layers of \ensuremath{\varepsilon}-GeSe [in the (0001) plane]. Frequency and temperature dependences and also relative changes of various acoustic-wave velocities

Acoustical properties of the human skull
The Journal of the Acoustical Society of America, 1978The acoustical properties insertion loss, reflection loss, and sound speed were measured on a series of fresh and subsequently formalin immersed human skulls. Measurements were made in the frequency range from 0.25 to 6 MHz. Most studies were restricted to an upper frequency limit of 2.2 MHz.

Alloys with Acoustic Properties
Applied Mechanics and Materials, 2014Considering that, in Accordance with the Laws of Physics, the Sound Travels only through Elastic Bodies, the Main Characteristic of an Acoustic Material is the Elasticity. Classifying the Metallic Materials in this Regard is Quite Difficult, as the Elasticity is Characterized by more than One Component (static Elastic Modulus, Dynamic Elastic Modulus ...

Acoustic Properties of Nanofibers
Noise & Vibration Worldwide, 2014In recent years nanofibers have been used in the field of applied acoustics to improve the acoustic characteristics of traditional materials without increasing their weight and size. In this paper acoustic measurements are reported of the absorption coefficient of porous materials coated with a layer of nanofibers carried out with the impedance tube (“

One of the defining thematic preoccupations in the fiction filmmaking of Philippe Grandrieux, one of the leading figures in French Art Cinema, is that of the politics of property. InSombre, La Vie Nouvelle, andUn Lac, the relationship dynamics between a woman and a variety of agents competing to claim her are mapped out in the overlap between different

Acoustical properties of “FABRASORB” acoustical fabrics
The Journal of the Acoustical Society of America, 1982“FABRASORD” acoustical fabric was developed by CHEMFAB about six years ago to provide a solution to the poor acoustics (U. S. Patent No. 4,152,474) within fabric structures. Based on woven fiberglass and polytetrafluoreotylene (PTFE) resins, it is a natural companion to “SHEERFILL” architectural fabrics which have enabled fabric structures to meet all ...
