A new approach to the room impulse response simulation
Archives of Acoustics, 2004 The most important problem of room acoustics is the evaluation of the acoustic quality of projected and modernized rooms. To this end it is necessary to work out a calculating impulse response algorithm for a digital room model.

Simulation and experimental study of room acoustics
, 2006 Sound propagation is a complex subject, especially in an enclosure. The study of room acoustics involves not only a research into how sound is propagated in a room, but also a search into how to measure sound under different condition and how to control ...

Advanced 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.

Geometrical room acoustics: ray based simulation for room acoustics
, 2016 Room acoustics is the science devoted to study sound propagation in enclosures where the sound conduction medium is bounded on all sides by walls, ceiling and floor. The acoustic information of any room, the so-called impulse response, is expressed in terms of the acoustic field as a function of space and time.

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

An acoustic paintbrush method for simulated spatial room impulse responses
, 2020 Virtual reality applications require all kinds of methods to create plausible virtual acoustics environments to enhance the user experi- ence. Here, we present an acoustic paintbrush method that modifies the timbre of a simple room acoustics simulation ...

Advanced Science, EarlyView.ZnSb reduces carrier concentration and suppresses Te volatilization, while Se substitution within QLs softens phonons and enhances anharmonicity. Swapped bilayers near twin boundaries strengthen phonon scattering and interlayer bonding. As a result, the optimal sample achieves an ultra‐high zT ∼1.51, cooling temperature difference of ∼70 K, power ...
