Catholic electroacoustical difficulties
ICASSP '85. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1985Electroacoustical difficulties are catholic, i.e. universal, in that 99.44% of the installed public address systems degrade speech intelligibility. We explain the causes for degradation in transportation terminals, hotel ballrooms, and churches. Severe difficulties are cited in the Memphis Air Terminal, St. Patrick's Cathedral in New York and all large

SEAT ELECTROACOUSTICAL TRANSDUCING
The Journal of the Acoustical Society of America, 2010An acoustic device, including an acoustic enclosure and a first electroacoustical transducing apparatus comprising a motor structure providing mechanical vibration, the vibration having a direction of vibration, mounted in the acoustic enclosure. The acoustic device is constructed and arranged so that first pressure waves are radiated from a first ...

Reciprocal relations in electroacoustics
The Journal of Chemical Physics, 2014In a colloidal suspension, one can generate sound waves by the application of an alternating electric field (Electrokinetic Sonic Amplitude, i.e., ESA). Another phenomenon is electrophoresis (Electrophoretic Mobility, i.e., EM) where a colloidal particle moves relative to the solvent in an electric field.

Electroacoustic characterization of trimmed hairy nanocelluloses.
Journal of Colloid and Interface Science, 2019OBJECTIVE A cellulose-derived nano-toolbox has been developed via the chemical nano-trimming of electrosterically stabilized nanocrystalline celluloses (ENCCs). ENCC is a member of the class of hairy nanocellulose (HNC). The objective of this study is to

This article introduces research on the influence of teaching on the change of inexperienced listeners’ appreciation of electroacoustic music. A curriculum was developed to make Key Stage 3 students (11–14 years old)1 familiar with electroacoustic music. The curriculum introduced music using concepts, such as music with real-world sounds and music with

Feasibility of Electroacoustic Tomography: A Simulation Study
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2019The feasibility of electroacoustic tomography (EAT) was investigated for in situ monitoring the electric field distribution in soft tissue. EAT exploits the phenomenon that the amplitude of acoustic emission generated by an electric field is proportional
