摘要:

This paper is derived from a “Hot Topics in Animal Bioacoustics” presentation at the 130th meeting of the Acoustical Society of America in St. Louis, Missouri. Six bioacoustics studies on a wide variety of species are discussed. Two of the studies are concerned with insects, the parasitoid fly, and cotton bollworms. The remaining bioacoustics studies are on aquatic animals including the West Indian manatee, elephant seals, and dolphins.

摘要:

An exact solution of the radiation force on a spherical object, when positioned on the acoustic axis of a cylindrical transducer, is provided. The solution is valid for any type of sphere of any size. The radiation force function allows the calibration of high-frequency focused ultrasound fields from radiation force measurements and expands the utility of the elastic sphere radiometer developed by Dunn et al. [Acustica38, 58–61 (1977)]. Numeral results reveal an oscillatory behavior of the radiation force function for small spheres near the transducer surface and this behavior may present an opportunity for particle sorting based on the mechanical properties of the particle and other types of manipulation.

摘要:

Structural acoustics often utilizes Fourier transformation to either reveal a phenomenon that is more directly recognized in one domain than in its Fourier conjugate domain or to employ complementarity in order to decipher a phenomenon. In this paper, a novel computational technique is introduced. This technique advantageously performs this transformation in situations in which specific spatial scales govern aliased factors in the integrand of a Fourier transformation. The technique can factorially save computational steps over corresponding computations that employ discrete Fourier transform procedures.

摘要:

Recently an efficient technique was proposed for performing a Fourier transformation on integrands that are composed of aliased factors. In this paper the proposed technique is utilized to perform Fourier transformations on quantities that pertain to the response of a regularly ribbed cylinder. The computations relate to Fourier transformations from the axial wave-number domain to the axial spatial domain. The phenomena of aliasing and pass bands and stop bands are of particular interest. It is argued that the complementarity of the data, when presented in the two Fourier conjugate domains, may be a useful analytical (and experimental) tool.
