Error microphones were located over the indoor window opening, while the cancelling sound sources along the periphery of the window void started from the lower corner of the outdoor window opening to the overlapping region of the window. The analysis was done using experimentally measured transfer functions of all related sound transmission paths. In general, the active control performance is better when more error microphones are adopted. The best sound reduction improvement reaches 6.80 dB over the frequency range from 100 Hz to 1 kHz when the reference microphone was mounted midway on the external window vertical frame. The control performance is weakened at a reduced number of error microphones in general. However, it is found that a simple system with three error microphones and two cancelling sources can achieve an average 5.2 dB broadband sound reduction improvement, when the reference microphone was located at the top of the outdoor window opening. While the former reference microphone position performs better when more error microphones and cancelling sources are adopted in a control system, the latter works better with simpler systems. Also, the present results suggest that it is better to keep the number of microphones larger than that of the cancelling sources and indicate the possibility of a coherence-based approach for locating reference microphone.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"245 ","pages":"Article 111220"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145884081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional prediction models often neglect the influence of hydrostatic pressure on wave propagation and energy dissipation, leading to limited accuracy. This study proposes an enhanced stiffness matrix method (E-SMM) that incorporates pre-stress effects into guided wave analysis to address this limitation. The approach first employs nonlinear static analysis to evaluate the initial stress-induced geometric stiffness under various hydrostatic pressures. This updated stiffness is then integrated into the stable stiffness matrix method (SMM) to derive pressure-dependent dispersion curves and wave attenuation coefficients. Using these coefficients, a modified transmission loss model is developed to quantify acoustic transmission across different laminate thicknesses, pressures, and frequencies. The model is validated against experimental data obtained from traveling wave tube measurements. The experimental results show that E-SMM captures key acoustic-structure interaction mechanisms—particularly pressure-dependent guided wave behaviour-leading to improved numerical stability and predictive accuracy. This makes it a valuable tool for designing high-performance underwater acoustic composite structures.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"245 ","pages":"Article 111202"},"PeriodicalIF":3.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145749024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To test this hypothesis, this research explored the effects of various sonic environments in ventilated classrooms while students were engaged in school tasks. Five sound conditions were compared, namely, quiet, three natural ventilation sounds coming from playground, birdsongs, and traffic respectively, and finally mechanical ventilation sound. Their effects on cognitive performance in calculation and reading comprehension, as well as on participants’ soundscape evaluations were assessed. A total of 229 students aged 11–14 years were tested in their own classrooms. The results (n of participants = 158) indicated that none of the sound conditions exerted a significant effect on reading comprehension, nor did they influence calculation accuracy. However, response times in calculation tasks improved in the presence of playground noise and deteriorate under mechanical ventilation noise. In terms of soundscape assessments, playground was rated as chaotic, mechanical ventilation as monotonous, whereas birdsongs is generally perceived as pleasant. The effects observed on cognitive performance were interpreted by resorting to arousal theory. In particular higher eventfulness seems to improve performance on the selected tasks.

This study presents a methodology to enable analysis of the spectral characteristics of the transient processes of room sound fields. The energy spectra appearing during the decay and growth processes for sinusoidal and white noise excitations are formulated by redefining energy-time functions in reference to previous findings. The derived formulae present a unified approach for the interrupted sine and noise methods. The energy spectrum is used to examine the spectral shift and broadening induced by out-of-band modes during transient processes. Frequency statistics, spectral bandwidth, and band energy ratios are introduced as physical indices. The proposed method was applied to analyze the decay process of actual room sound fields following preliminary examinations using room impulse responses generated by numerical simulations. The results indicate that the effect of out-of-band modes was insignificant when the product of the excitation bandwidth and reverberation time exceeded 18 and 36, respectively, in cases with and without acoustic modal overlap. Band limiting of the received signal may not always be necessary under these conditions. In concert halls, this condition was satisfied even when the excitation bandwidth was a 1/12 octave.

This class of materials results from the combination of multiscale sorptive porous materials, which possess characteristic sizes ranging from nanometres up to millimetres, a mesopore fluid network, and local acoustic resonators. The two-scale asymptotic homogenisation method is used to establish the macroscopic equations that describe sound propagation through the investigated class of materials. The upscaling process unveils the key role of internal mass sources, activated by pressure, on the macroscopic mass balance, while the macroscopic fluid flow constitutive law remains classical. Phenomena such as inner acoustic resonances, multiple types of diffusion, visco-thermal dissipation across scales, and sorption at the nanoscale, are shown to determine the atypical effective compressibility of the fluid equivalent to the metamaterial. The dynamic permeability behaves classically, however, and is determined by the most permeable local constituent. We develop an analytical model for a material with a specific microstructure and successfully validate it against numerical pore-scale simulations and experimental data from a prototype sample whose key building-block elements are granular activated carbon and 3D-printed acoustic resonators.

Therefore, bio-based materials draw increasing attention in research literature, especially when utilized as thermal and acoustic insulation. Traditional materials predominantly used as acoustic materials, such as mineral wools, incur substantial energy consumption during production, primarily through the melting of sand. In contrast, bio-based materials offer promising alternatives to current market leaders potentially achieving negative carbon footprints due to their low embodied energy and high carbon content. When sourced from industrial by-products, these materials have the ability to store carbon in buildings for decades. It is crucial to investigate the porous structures of these bio-fibrous materials to unlock their full potential. Therefore, this study focuses on the prediction and characterization of foam-formed softwood-based fibers and their acoustic properties. By evaluating analytical models, semi-phenomenological models, and experimental measurements, the prediction of sound absorption based on fiber diameter and density is assessed. Moreover, the material synthesis process and characterization are adapted to achieve a wider range of densities while taking elastic properties into account.

Recent studies have explored graph Fourier transform (GFT)-based features and graph frequency cepstral coefficients for replay speech detection. However, these methods often suffer from unstable graph spectral differences between genuine and replayed speech, caused by sensitivity in the graph Fourier basis (i.e., GFT with eigenvalue decomposition). This instability limits the effectiveness of graph frequency cepstral coefficient features for reliable replay attack detection. To address this, we propose constructing robust undirected graph topologies using an exponential function and graph shift operator. Based on these graph topologies, we derive stable graph Laplacian matrices with singular value decomposition to define the logarithmic graph Fourier transform and logarithmic joint graph Fourier transform. These enable extraction of enhanced (joint) graph frequency cepstral coefficient features for replay attack detection. Experimental results on the ASVspoof dataset show that ASV systems utilizing our (joint) graph frequency cepstral coefficient features significantly outperform current state-of-the-art methods on the ASVspoof datasets.
