A COMSOL–MATLAB Coupled Optimization Framework for Cost-Effective Acoustic Renovation of Educational Buildings Using Wood-Based Materials

open access: yesBuildings
Poor classroom acoustic conditions can impair speech intelligibility, increase cognitive load, and reduce the quality of learning environments. Simulation-guided optimization provides a promising approach for improving building acoustic performance and ...

Speech Intelligibility Test for Polish Language – Relation to the Acoustic Properties of Classrooms and Comparison to Other Languages

open access: yesArchives of Acoustics, 2018
Numerous studies have shown that teachers often speak louder in classrooms because of the acoustic properties of the spaces. To improve the acoustics in classrooms, it is necessary to develop relevant acoustic criteria.

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

open access: yesAdvanced 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,

The influence of discrete arriving reflections on perceived intelligibility and speech transmission index measurements

open access: yes, 2016
The most widely used objective intelligibility measurement method, the Speech Transmission Index (STI), does not completely match the highly complex auditory perception and human hearing system.

An experimental study of a time-frame implementation of the Speech Transmission Index in fluctuating speech-like noise conditions

open access: yes, 2019
Everyday communication takes place in the combined presence of reverberation and background noise, the latter having in some cases fluctuating characteristics and speech-like spectrum. To predict the speech intelligibility for fluctuating maskers, a time-

Logatome and Sentence Recognition Related to Acoustic Parameters of Enclosures

open access: yesArchives of Acoustics, 2017
The paper deals with relationship between speech recognition and objective parameters of enclosures. Six enclosures were chosen: a church, an assembly hall of a music school, two courtrooms of different volumes, a typical auditorium and a university ...

Crowd noise spectra for the calculation of the speech transmission index for public address systems [PDF]

open access: yes
Knowledge of interfering noise is necessary for the correct design of a public address system. Noise sound levels can be obtained, for example, from BS 5389-1.

Speech intelligibility in halls with Reverberation Enhancement Systems

open access: yesActa Acustica
Speech intelligibility is one of the most important aspects of room acoustics and is commonly evaluated in relation to objective parameters such as Reverberation Time (RT), Early Decay Time (EDT), and Clarity for speech (C50).

Deciphering the Photopolymerization‐Induced Nanostructures and Interface Formation for Submicrometer Additive Manufacturing

open access: yesAdvanced Functional Materials, EarlyView.
This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...
