Evaluation and Surgical Treatment of Acoustic Neuroma
New England Journal of Medicine, 1972Abstract In 46 consecutive patients treated surgically for acoustic neuroma and followed for a minimum of two years, there was no operative mortality; 90 per cent returned to their previous level of activity, and all were able to care for themselves. Total removal of tumor was possible in 70 per cent, and radical subtotal removal in another 10 per cent.

Apparatus for attentuating noise emitted from an inlet port to a centrifugal fan comprises a panel member which is mounted in spaced confronting relationship to the inlet port and includes a rigid backing member, a facing mounted in spaced disposition from the rigid backing member, partitions dividing the space between the rigid backing member and the ...

Tumor treatment by time-reversal acoustics
1999 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings. ICASSP99 (Cat. No.99CH36258), 1999There has been a great deal of work in ocean science over the last 10 years in using acoustic channel models in the signal processing. The goal has been to compensate for the "barbershop" effect in which a sonar system confuses the true source with its reflections in the acoustic mirrors formed by the ocean surface and bottom.

We call building materials “acoustic treatment” when they change the response of a room to sounds that occur in it. Absorption reduces the reverberation time of a room as well as strength. Reverberant chambers increase the cubic volume of the room and increase the reverberation time without significantly changing the strength.

On the surgical treatment of bilateral acoustic neurinomas
Acta Neurochirurgica, 1964The frequency of bilateral acoustic tumours is about 2.5% of all acoustic neurinomas. In different series in the literature and in our personal material we found altogether 25 examples of such bilateral lesions; 15 of them presented signs of von Recklinghausen's disease.

History of the Diagnosis and Treatment of Acoustic Neuroma
Archives of Otolaryngology - Head and Neck Surgery, 1968THE DEVELOPMENT of acoustic neuroma diagnosis and surgery is one of the most fascinating sagas of medical history. This story will be traced from the first recorded postmortem description of these tumors until the present time. Development and diagnostic tests, general supportive care, and surgical techniques are to be emphasized from time to time.

Acoustics Treatment for University Halls
2018This paper aims to solve one important problem while designing halls with domes in universities such as a central lobby of Architectural Engineering Department at the University of Sharjah. Most architects consider aspects/factors of esthetics, form, function, and to some extent sustainability besides illumination, but in general they drop issues of ...

What Acoustical Treatment Will and Will Not Do
The Journal of the Acoustical Society of America, 1940It is sometimes found that acoustical materials, installed for the purpose of correcting auditorium acoustics or quieting noise, produce results which either exceed or fall short of expectations. A number of typical examples are described and explained in terms of the physical and psychological factors involved.
