A theoretical model based on mass-spring-damping parameters is used to analyze the transmission loss of Helmholtz resonators in ducts.

The ‘reactance-to-resistance’ effect is proposed to occur between resonators when placed in parallel. The results indicate that damping in a Helmholtz resonator can be used to achieve a balance between reflection and absorption effects. Resonator spacing influences system mass modification, revealing wavelength-related cyclic patterns.

Distributed acoustic sensing (DAS) has emerged as a powerful acoustic-based technology for monitoring, measurement, and verification, transforming standard fibre-optic cables into dense seismic arrays. This review focuses on DAS deployment strategies and their real-world performance across landmark CO<sub>2</sub> storage projects including Otway (Australia), Aquistore and Quest (Canada), CarbonSAFE (USA), and Minami-Aga (Japan). Case studies illustrate both the promise and limitations of DAS in diverse settings such as cemented vertical wells, retrofitted observation wells, surface-deployed arrays, and offshore telecommunication cables. A critical theme across deployments is the pervasive challenge of noise contamination (thermal fluctuations, mechanical vibrations, hydraulic disturbances, and offshore environmental noise) which degrade signal fidelity and complicate interpretation. These acoustic interferences, compounded by issues of fibre–formation coupling, axial strain sensitivity, and offshore repeatability, highlight why DAS remains underutilized despite its unrivalled spatial density and temporal continuity. By synthesizing lessons from field applications, this review underscores how DAS can advance acoustic monitoring of CO<sub>2</sub> storage while identifying the technical and regulatory barriers that must be overcome for its integration into large-scale, reliable subsurface surveillance frameworks. </p></div>","PeriodicalId":54355,"journal":{"name":"Acoustics Australia","volume":"54 :","pages":"255 - 288"},"PeriodicalIF":1.8,"publicationDate":"2026-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148011906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Unfortunately, UANs operate within a limited acoustic spectrum, where these spectrums often overlap with those used by marine animals for communication, navigation and foraging. Additionally, anthropogenic noise from industrial activities contributes to acoustic pollution, intensifying this problem. This frequency overlap poses significant risks to marine life. Therefore, this review highlights the urgent need to develop environmentally aware UANs that minimize harmful acoustic interference with marine mammals, fish and invertebrates. Further, it focuses on network design challenges, examining their negative impacts, defining the concept of a marine-friendly network and establishing evaluation metrics to assess performance. This paper classifies existing marine-friendly UAN approaches into three main categories: spectrum management methods (including cognitive acoustic technologies), eco-friendly routing protocols, and prediction-based techniques. Each category is analyzed in terms of its strengths and limitations. Lastly, the review identifies current research gaps and outlines future directions to support the development of marine-friendly UANs that can effectively balance communication performance with marine conservation, toward a sustainable network.</p></div>","PeriodicalId":54355,"journal":{"name":"Acoustics Australia","volume":"54 :","pages":"231 - 254"},"PeriodicalIF":1.8,"publicationDate":"2025-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148011905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Predictions from these analytical models are compared with predictions from boundary element and finite element numerical models and also experimental results. The hydroacoustic experiment is conducted in the water tank located at Defence Science and Technology Group, Melbourne. The numerical simulations and experiments demonstrate that the vibro-acoustic coupling of the duct wall with the fluid leads to a change in the effective speed of sound in the duct and consequently the resonant frequency of the system. Therefore, using a rigid duct approximation would lead to an over prediction in the effective speed of sound in the duct and, for the example presented in the paper, an over prediction in the relative gain in sound power from placing a monopole in the duct. The method of images and transmission matrix models are shown to accurately predict the relative gain in sound power for a rigid duct. The current experimental set-up requires a source with greater acoustic power to allow future investigation of duct cross modes and dipole sources.</p></div>","PeriodicalId":54355,"journal":{"name":"Acoustics Australia","volume":"54 :","pages":"47 - 62"},"PeriodicalIF":1.8,"publicationDate":"2025-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148012006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Conventionally, scaled measurements employ a high-frequency impulse source combined with a stepwise rotating turntable. In this approach, 72 impulse responses are recorded at 5° increments and averaged to obtain the specular reflected impulse response. However, for asymmetric specimens, scattering characteristics vary at each angle, and relying solely on fixed angular responses neglects other directional properties. In this study, a “spark train” sound source was introduced to measure scattering coefficients in a 1:10 scaled reverberation chamber using a continuous rotation approach. A high-frequency impulse source was coupled with a continuously rotating turntable. Once the impulse was emitted, the turntable rotated without interruption, and the reflected sound in the nonlinear impulse response represented an integration of scattering contributions from multiple angles. Experimental results demonstrated that the scattering coefficients obtained with this method align more closely with full-scale measurements based on MLS signals. In addition, the effects of turntable rotation status, source emission interval, air absorption correction methods and test specimen sampling geometry on the accuracy of measured scattering coefficients were analyzed in detail.</p></div>","PeriodicalId":54355,"journal":{"name":"Acoustics Australia","volume":"54 :","pages":"145 - 158"},"PeriodicalIF":1.8,"publicationDate":"2025-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148011902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

It recommends that impulsive sound that is suspected of being caused by sources of residual sound is to be excluded from analysis. It is common when conducting a noise survey at receptors which are located some distance from an intrusive noise source using long-term monitoring data that residual sound, such as from traffic, aircraft, birds, and insects, is a significant noise contributor.
