Imaging Acoustics and Acoustic Imaging

2002
This paper provides a brief overview of some of the techniques for imaging acoustic waves inside and on the surface of solids. Optical methods show the influence of material anisotropy on acoustical wave propagation in transparent solids. Multiple-pulse holography images waves on the surface of materials without the necessity of scanning.

Acoustic Neuromas and the Acoustic Impedance of the Ear

Journal of Speech and Hearing Disorders, 1973
The acoustic impedance at the tympanic membrane was measured at frequencies in the range 100–1000 Hz and found to be abnormal on the affected side in four patients with acoustic neuroma. In all four the resistance was abnormally high at low frequencies on the affected side, and in three the reactance of the affected ear was raised relative to that of ...

Acoustic cavitation and implosion acoustics

The Journal of the Acoustical Society of America, 1996
The ubiquitous cavitation bubble always seems to be around whenever one propagates an acoustic field of moderate amplitude through a liquid. The implosive collapse is a marvelously efficient concentrator of acoustic energy and can result in exotic mechanical and chemical effects. Examples of some of the many ways this acoustic energy can be utilized to

Nonlinear Acoustics and Acoustic Chaos

2002
The very basic standard elements of nonlinear acoustics are presented: The origin of nonlinearity, equations of state, simple nonlinear waves and shock wave formation. Sonoluminescence is chosen as a modern example of nonlinear acoustics. Some notations from nonlinear dynamics are introduced needed for understanding chaotic dynamics and acoustic ...

Acoustical standards in engineering acoustics

The Journal of the Acoustical Society of America, 2004
The Engineering Acoustics Technical Committee is concerned with the evolution and improvement of acoustical techniques and apparatus, and with the promotion of new applications of acoustics. As cited in the Membership Directory and Handbook (2002), the interest areas include transducers and arrays; underwater acoustic systems; acoustical ...

Acoustics of the Intonarumori

The Journal of the Acoustical Society of America, 2005
The Intonarumori were a family of musical instruments invented by the Italian futurist composer and painter Luigi Russolo. Each Intonarumori was made of a wooden parallelepiped sound box, inside which a wheel of different sizes and materials was setting into vibration a catgut or metal string.

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 ...
