However, the local subtropical climate characterized by high temperatures and heavy rainfall accelerates void reduction in porous asphalt roads. Previous studies have primarily investigated how void clogging affects pavement’s hydraulic permeability but paid insufficient attention to the influence on acoustic performance. Furthermore, existing research on void reduction has mainly focused on clogging while neglecting the compaction effect caused by traffic loads. This study aims to investigate and compare the acoustic deterioration characteristics in porous asphalt pavement induced by clogging and deformation. Impedance tube tests revealed that clogging changed the sound absorption coefficient spectrum of porous asphalt from a single peak to a dual peak pattern within 0–1,600 Hz, while rutting-induced deformation transformed a multi-peak pattern into a single peak spectrum across 0–6,400 Hz. Rubber ball free fall impact tests further demonstrated that clogging significantly increases airborne noise emissions, particularly in medium-to-high frequencies (500–8,000 Hz), with a pronounced increase at ∼2,500 Hz. Clogging caused the porous asphalt specimen to evolve from a homogeneous acoustic medium to a stratified system with depth-dependent impedance. By contrast, rutting produced an overall structural compaction of the porous asphalt mixture, degrading its noise reduction ability, especially notably at high frequencies (>2,000 Hz). These findings provide critical insights into the acoustic deterioration of porous asphalt pavements, offering a foundation for more durable low-noise pavement design.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"244 ","pages":"Article 111163"},"PeriodicalIF":3.4,"publicationDate":"2026-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145571920","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, the psychophysiological mechanisms behind these effects at different sound pressure levels (SPLs) remain unclear. This study investigated the restorative effects of birdsong at five SPLs—40, 45, 50, 55, and 60 dB(A)—using the Perceived Restorativeness Scale (PRS) and electroencephalography (EEG) with 30 participants. Subjective evaluations identified 45 dB(A) as optimal for stress relief, with PRS total scores increasing by 0.97–1.62 compared to silent (40 dB(A)) and higher (55–60 dB(A)) SPLs. Fascination and compatibility scores declined significantly above 55 dB(A). Physiologically, birdsong at 45–50 dB(A) enhanced alpha wave activity by 14.1 %, relative to the 40 dB(A) condition, indicating mental relaxation. In contrast, 60 dB(A) increased EEG mental stress by 29 %. Event-related potential (ERP) analysis revealed that 40–50 dB(A) range strongly activated the P300 component, with average amplitudes of 0.15–0.29 μV at the Pz channel, reflecting a higher relation. The LPP component attained its average amplitude (0.14 μV) in the Pz channel under 60 dB(A), indicating intensified emotional processing associated with stress. This activation pattern demonstrated that the stress recovery process engaged activity in the brain’s parietal lobe. A Random Forest model using ERP features achieved 71.4 % classification accuracy, confirming the utility of ERP as a physiological indicator. Polynomial regression identified 53.6 dB(A) as the upper SPL threshold for restorative benefits. These findings offer a scientific basis for designing restorative sound environments and highlight ERP analysis as an effective tool for evaluating natural soundscapes.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"243 ","pages":"Article 111155"},"PeriodicalIF":3.4,"publicationDate":"2026-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145528567","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}

The results show that diver echoes primarily arise from scattering by the gas cylinder, diving suit, fins, and respiratory bubbles. Differences in breathing apparatuses lead to distinct echo patterns, including continuous and intermittent echoes, while respiratory bubbles and fin movements exhibit periodic echo features that vary with diver swimming activities.

Normal-hearing participants completed clerical tasks, including reading, note-taking, and writing, in four different auditory conditions combining two speech intelligibility levels and simulated hearing loss. Subjective assessment of workload, fatigue, and noise annoyance were collected alongside task performance metrics. Results indicated that speech intelligibility affects performance equally across both hearing conditions, suggesting that mild hearing loss does not significantly alter susceptibility to distraction in open-plan offices.

Conventional noise control devices inherently face a trade-off between noise attenuation performance and ventilation efficiency. To address this challenge, this study presents a ventilated acoustic metamaterial that combines a massless, stress-free thermoplastic polyurethane (TPU) membrane with cascaded Helmholtz resonator (membrane-cascaded HR). By modulating the membrane’s placement within the membrane-cascaded HR cavity, the structure enables frequency tuning without altering unit dimensions, thus facilitating efficient noise mitigation in confined geometries. Finite element simulations and experimental results validate that the proposed membrane-cascaded HR group achieves a broadband sound transmission loss (STL) exceeding 10 dB in the low frequency range. Remarkably, the compact membrane-cascaded HR group features sub-wavelength dimensions and exceptional parametric stability. Composed of seven units, it maintains robust performance under 30 % variations in TPU membrane Young’s modulus (14–20 MPa). Experimental validations in both straight and curved ducts confirm consistent frequency-selective attenuation performance.

To synthesize new speakers’ speech with only a few minutes of data, adapter-based few-shot learning has been proposed. This approach inserts lightweight modules into a pre-trained multi-speaker backbone, effectively preserving its quality while adding new voices with minimal parameter overhead. However, existing adapter-based few-shot learning methods support only single-speaker adaptation—each new speaker requires its own adapter, leading to increased parameters. To overcome this limitation, we propose Hyper-MoA, which integrates a Hyper-network with a Mixture-of-Adapters framework to enable multi-speaker adaptation within a single module. Hyper-MoA operates in a speaker-specific manner, allowing one module to accommodate any number of new speakers without increasing model size. During adaptation, it learns shared representations through speaker interactions, alleviating performance degradation caused by limited data in few-shot scenarios. Experiments under varied speaker counts, data amounts, and adapter compression settings demonstrate that Hyper-MoA consistently outperforms conventional MoA while delivering significant parameter savings—confirming its effectiveness and efficiency for few-shot multi-speaker TTS adaptation.</div></div>","PeriodicalId":55506,"journal":{"name":"Applied Acoustics","volume":"243 ","pages":"Article 111118"},"PeriodicalIF":3.4,"publicationDate":"2026-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145424919","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}
