From the earliest stages of Greek thought, sound was thought to originate as the result of an impact between two objects. At first it was believed that the swiftness and force of the impact affected both volume and pitch; then it became clear that these were two different parameters.

The Journal of the Acoustical Society of America, 1985
Acoustic cavitation has been found to belong to the class of deterministically chaotic systems [W. Lauterborn and E. Cramer, Phys. Rev. Lett. 47, 1445 (1981); W. Lauterborn and E. Suchla, Phys. Rev. Lett. 53, 2304 (1984)]. Experiments are described in further support of this view by constructing phase spaces from measured data and by determining the ...

Current Treatment Options in Neurology, 2002
Patients with acoustic neuromas have several treatment options that include observation, surgical resection, stereotactic radiosurgery, and fractionated radiotherapy. Resection is indicated for patients with larger tumors that have caused major neurologic deficits from brain compression.

Acoustical barrier with acoustical seal
The Journal of the Acoustical Society of America, 1994An acoustical barrier, an aperture and a pipe or cable passing therethrough wherein the aperture has a number of radially extending slits which define a plurality of radial sectors which also extend from the aperture. One or more grooves are arranged in the sectors concentrically about the aperture to increase the radial flexibility of the sectors so ...

Previous to the development of amplifiers most of the instruments used in acoustical research depended for their operation upon purely mechanical principles. This paper includes a brief survey of such of these instruments as are still of interest in connection with the investigation of technical or research problems in acoustics, but it deals primarily

In the setting of a voice clinic, the voice may be assessed in a number of different ways. As a bare minimum, assessment should include stroboscopic examination, patient self-reported questionnaires, and clinician-reported perceptual evaluation. In addition, recordings of the voice may be analyzed using computer software: several different measures ...

Holographic techniques are fundamental to applications such as volumetric displays, high-density data storage and optical tweezers that require spatial control of intricate optical or acoustic fields within a three-dimensional volume. The basis of holography is spatial storage of the phase and/or amplitude profile of the desired wavefront in a manner ...

Soviet Physics Uspekhi, 1987
The thirtieth anniversary of the discovery of the laser is celebrated in 1990. Modern lasers emit in a wide range of wavelengths and major progress has been made in the development of tunable dye lasers, as well as of gas and solid-state lasers.

The acoustic microscope is a new entry in the field of microscopic imaging. It comes after a delay of many years, but now appears to be well established. At last year's conference of the Royal Microscopical Society in London, for example, the booth traditionally reserved for new instruments was used to introduce commercial versions of acoustic ...
