Selective Arcing Electrostatically Eradicates Rice Weevils in Rice Grains
Insects, 2021 We developed an arc discharge exposer (ADE) that kills rice weevils nesting in dried rice. The ADE features multiple identical metal plates, half of these are linked to a voltage generator and the others are grounded.

The Calibration of Heart Sound Intensity [PDF]
Circulation, 1956 There is no standardized method for the calibration of total energy conducted to the surface of the chest caused by the cardiac sounds. Loudness is a subjective term which is dependent upon total energy, frequency of the main components and the specific sensitivity of the human hearing mechanism.

Sound intensity measurement for impulsive sounds [PDF]
The Journal of the Acoustical Society of America, 1988 For the measurement of sound radiation properties caused by structure-borne sound from large structures such as buildings and bridges, impact excitation is much more advantageous and convenient than stationary random excitation. The application of the sound intensity method to such sound radiation measurements was investigated.

The Functional Anatomy of Sound Intensity Discrimination [PDF]
The Journal of Neuroscience, 1998 The human neuroanatomical substrate of sound intensity discrimination was investigated by combining psychoacoustics and functional neuroimaging. Seven normal subjects were trained to detect deviant sounds presented with a slightly higher intensity than a standard harmonic sound, using a Go/No Go paradigm.
