Distributed Estimation And Equalization Of Room Acoustics In A Wireless Acoustic Sensor Network

, 2012
In this paper, the use of a wireless acoustic sensor network (WASN) for the estimation and equalization of room acoustics is proposed as a flexible and promising alternative to the traditional wired implementations. We consider a multiple-point equalization problem based on a common-acoustical-pole (CAP) room model.

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,
