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 ...

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.

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, 2010
It is now well understood how coordinate transformations of the Maxwell equations can be interpreted in terms of an electromagnetic material in the original coordinates with transformed values of permittivity and permeability. Through this transformation optics approach, the bending and stretching of electromagnetic fields specified by coordinate ...

The Journal of the Acoustical Society of America, 1935
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

Trends in Biochemical Sciences, 1977
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 ...

The basics of nonlinear acoustics and its application to medical ultrasound imaging are introduced. First, a little historical introduction is given, and next, the coefficient of nonlinearity is introduced, together with a variety of equations, which step by step develop from simple to more sophisticated models.

Physics Today, 1955
AN INTELLECTUALLY VITAL and stimulating field, acoustics is rich in unsolved and intriguing research problems. Its areas of interest are pertinent to the activities of many traditional university departments: mathematics, physics, electrical engineering, mechanical engineering, land and naval architecture, behavioral sciences and even biology, medicine

International Journal of Bifurcation and Chaos, 1991
The history of chaos pertaining to acoustics is briefly reviewed from the first period-doubling experiments reported by Faraday (vibrated liquid layer) and Melde (string oscillations) to today's investigations on chaos in thermoacoustics, musical instruments, the hearing process, and ultrasonics.

Theoretical and Computational Fluid Dynamics, 1998
We discuss two types of acoustic streaming, namely the ``quartz wind'' and Rayleigh streaming. Both are associated with flows that are dominated by their fluctuating components, and owe their origin to the action of Reynolds stresses. In the former, these stresses arise within the main body of the fluid when an ultrasonic beam propagates into it; in ...
