Acoustic Assessment

2020
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 ...

Acoustic neuromas

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.

acoustics

2016
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.

Transformation acoustics.

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 ...

Acoustical Instruments

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

Acoustic microscopy

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 ...

Classroom Acoustics

The SAGE Encyclopedia of Human Communication Sciences and Disorders, 2019
ore than three-quarters of the teachers in a recent poll gave the acoustics in their classrooms a failing grade. The problem is most commonly a "signal to noise" ratio issue, which results in poor speech intelligibility.
