Acoustic analogs for the characterization room electromagnetics
The Journal of the Acoustical Society of America, 2017In indoor wireless communication the radio channel is comprised of the direct and diffuse multipath components. As in the acoustics case these diffuse components are the result of non-specular and random scattering. This state-of-affairs is particularly problematic for short-range millimeter wavelength radio system.

Analog acoustic expression in speech communication
Journal of Memory and Language, 2006Abstract We present the first experimental evidence of a phenomenon in speech communication we call “analog acoustic expression.” Speech is generally thought of as conveying information in two distinct ways: discrete linguistic-symbolic units such as words and sentences represent linguistic meaning, and continuous prosodic forms convey information ...

Quantum logic gate analogies in nonlinear acoustics
The Journal of the Acoustical Society of AmericaThis study introduces a framework using acoustic phase bits (phibits) as classical analogs to quantum bits for realizing quantum-like gates. These phibits are realized on a metastructure composed of aluminum rods glued with epoxy. First, we realize a single phibit gate in a general form for a Bloch sphere representation, providing a foundation for ...

Moiré Fringe Analogs in Underwater Acoustics
The Journal of the Acoustical Society of America, 1961Recently, the writer described a moiré fringe analog for underwater sound modes. Now, attention is given to the work of Pohl and Shubnikov with moiré patterns from circular grids which are of possible use in underwater array design and underwater sound propagation investigations.

An Analog Electronic Correlator for Acoustic Measurements
The Journal of the Acoustical Society of America, 1955A study has been made of the applicability of correlation techniques to the field of acoustic measurements. The development of an analog electronic correlator for this study is reported here while the application of the correlation technique to some acoustic measurements is reported in a companion paper.

Acoustic Surface Wave Analog Filters
1972 IEEE GMTT International Microwave Symposium, 1972While the basic principles of surface wave device operation have been described previously, this paper describes the unification of this modeling information into a design synthesis procedure. Also, the excellent performance of the resulting devices is discussed. Emphasis is given to bandpass filters.

Acoustical analogs of condensed-matter problems
Reviews of Modern Physics, 2001As a result of advances in experimental and theoretical physics, many interesting problems have arisen in condensed-matter physics, typically as a result of the quantum-mechanical nature of a system. Areas of interest include Anderson localization, universal conductance fluctuations, normal electron persistent currents, and the properties of ...
