Studying the frequency spectrum of acoustic emission signals by the infradyne transform method
Известия высших учебных заведений. Поволжский регион: Физико-математические наукиBackground. The process of formation and development of microcracks in the walls of a tank with liquefied hydrocarbons can inevitably lead to a breach of tightness and, as a consequence, to the creation of a fire-hazardous situation and, yes, an ...

Piezoresistive Effect: A New Concept for Hearing Aids
Advanced Science, EarlyView.An MXene/PVA sound sensor utilizing piezoresistive effects has been proposed with a detection limit of 60 dB and a frequency response of 20–4000 Hz, which is comparable to the performance of commercial hearing aids. By combining the sensor with machine learning, the accuracy rate of voiceprint recognition of wildlife conservation can reach up to 99 ...

Advanced Science, EarlyView.A simple to multiscale structure transition happens when a commercial porous foam is filled with multiwall carbon nanotubes with high aspect ratio. For an acoustic absorber with a porous material, the loading of multiwall carbon nanotubes can significantly improve its specific surface area while preserving its thickness and high porosity, thus enables ...
