Recent advances on active control of sound transmission through ventilation windows

open access: yes, 2017
Windows are often the weakest part in a building in terms of sound transmission loss from outside. Many researchers have applied active noise control to improve the sound transmission loss of windows, which includes distributing an array of loudspeakers ...

Defect Driven Electronic Structure Reconfiguration and Hierarchical Phonon Suppression in Ag2Se Thermoelectrics

open access: yesAdvanced Science, EarlyView.
Indium substitution in Ag2Se nanocrystals simultaneously tailors electronic structure and lattice dynamics. Fermi‐level upshift and band‐gap narrowing enhance electrical transport, while defect‐induced lattice softening intensifies phonon scattering and suppresses lattice thermal conductivity.

THE TRANSMISSION OF SOUND THROUGH SEA WATER [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1932
During the past year experiments have been made by the U. S. Coast and Geodetic Survey to determine the horizontal path of sound through sea water and valuable information has been obtained. Two ships on the Pacific Coast operated in depths of about 1000 fathoms and many oscillograph and chronograph records were made of small bombs fired near the ...

Impedance‐Matched High‐Overtone Thickness‐Shear Bulk Acoustic Resonators With Scalable Mode Volume

open access: yesAdvanced Science, EarlyView.
A bottom‐electrode‐free high‐overtone bulk acoustic resonator is achieved by lateral excitation of antisymmetric thickness‐shear modes on a lithium‐niobate‐on‐silicon platform. Planar electrode geometry eliminates conventional loading along the resonance path and confines acoustic energy within the electrode gap.
