However, when identical stimuli are presented to both ears simultaneously, binaural interactions occur, complicating the identification of each ear's true response. Thus, this study applies the spread spectrum technology to ABR testing by employing a random stimulus rate for each ear, enabling simultaneous and independent assessment of bilateral ears (ssBi-ABR). The ssBi-ABR results were compared with traditional unilateral auditory brainstem response (uABR) results to examine the effectiveness of the ssBi-ABR method. No significant difference in the response threshold was observed between the two methods. Although ssBi-ABR showed significantly longer latencies (except wave I) and lower amplitudes than uABR, the average differences were both relatively small (<0.1 ms and <0.1 μV). The testing duration of ssBi-ABR was significantly shorter than that of uABR, on average, requiring only 63% of the time needed for uABR. The findings demonstrate that the application of spread spectrum technology enables effective and simultaneous bilateral ABR testing, which could significantly reduce the testing time without compromising the accuracy of the results.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"1646-1652"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144958616","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}

Acoustic data from a vertical line array in the northern South China Sea, combined with sound speed profiles, seabed properties, and multi-source wind fields (ERA5 reanalysis/Weibull-distributed synthetics), demonstrate: (1) A 20-km spatial noise-energy threshold (>90% energy contribution), challenging conventional near-field assumptions (1-2 km); (2) frequency-dependent distribution: low-frequency (50-200 Hz) directionality depends on near-field sources, while high-frequency (>400 Hz) energy shifts seaward due to modal cutoff variations; (3) model validation shows 0.96 correlation at 100 Hz/100 km (stratified medium accuracy), but seabed interface waves induce 3.8 dB deviation at 50 Hz; (4) wind heterogeneity thresholds: uniform wind approximation causes negligible error (<0.01 dB) under weak gradients (0.36 knots/km) but significant error (1.47 dB at 50 Hz/20 km) under strong gradients (8.23 knots/km); (5) strong wind gradient-frequency coupling yields stable ± 17° grazing-angle biases below 400 Hz versus high-frequency anomalies at large angles.

The parallel broadband Helmholtz FMBEM is used to model each fluid domain, while the elastic inclusion is modelled using either the finite element method, or an analogous elastodynamic FMBEM. The boundary integral equation for each fluid half-space is formulated to account for the transmission and reflection of the incident acoustic field from the planar surface of the interface, and so only the scattered field from the elastic inclusion and/or localised surface scattering features on the interface surface are evaluated. In the absence of specialised methods to absorb the outgoing waves, the scattered field will reflect from the edge of the truncated boundary element mesh representing the fluid-fluid interface. Numerical examples demonstrate that the resulting errors can be minimised when the truncated mesh is made a few times larger than the scattering feature. The boundary-only discretisation of the truncated fluid-fluid interface, O(N log N) computational cost of the FMBEM, and simplified truncation of the boundary mesh yield a computationally efficient model for fully three-dimensional analysis for this type of problem configuration.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"1802-1818"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144992891","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}

Recently, physical-model-based approaches have made significant progress, with higher accuracy and fewer sampling requirements than conventional methods. Nevertheless, it remains a challenge to reconstruct three-dimensional outgoing sound waves in the volume surrounding a sound source due to constraints on existing methods both in mathematical formulation and measurement systems. In this paper, we propose spherical harmonic-domain AOT, a three-dimensional reconstruction of sound fields by combining instantaneous sound-field imaging using parallel phase-shifting interferometry with a physics-based reconstruction using spherical wave function expansions. We formulated two problems: one for the sound field radiated by a transducer and the other for the sound field scattered by an object. Through experiments, we demonstrated the successful reconstruction of the two types of three-dimensional sound fields: one radiated from two ultrasonic transducers and the other scattered by an ellipsoid.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"1688-1699"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144958655","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}

Environmental measurements were obtained using a wave-sensing conductivity, temperature, and depth probe. Seafloor roughness was estimated using stereo imaging techniques on underwater photographs. The measured seafloor scattering strengths were averaged over calm periods between storm events. The overall levels and trends are compared to predictions from the small-slope approximation model.

This study focuses on estimating the range between an acoustic receiver and a transiting ship in an acoustically range-independent shallow water environment. Here, acoustic propagation can be modeled by a set of modes that are determined by the shallow water waveguide and seabed characteristics. These modes are dispersive, with phase and group velocities varying with frequency, and their interference produces striation patterns that depend on range and frequency in single-hydrophone spectrograms. These striation patterns can often be characterized by the waveguide invariant (WI), a single parameter describing the waveguide's properties. This paper presents a statistical model and corresponding WI-based range estimation approach using a single hydrophone, leveraging broadband and tonal sounds from a transiting ship. Using data from the Seabed Characterization Experiment 2017 (SBCEX17), the method was evaluated on two commercial ships under different environmental conditions and frequency bands. Range estimation errors remained below ±4% up to 62 km in the best case, with robust performance demonstrated in the 40-60 Hz band.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2448-2463"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145137818","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}

Ten adult male Japanese speakers produced sustained vowels /a/ and /i/ under quiet and noisy conditions involving three noise types (broadband, low-pass, and high-pass) at 75 and 85 dB. We analyzed vocal intensity and the amplitudes and frequencies of the F1 and F2. Auditory spectral representations, simulated using a loudness model, were used to estimate excitation patterns in the auditory periphery. Most noise conditions significantly increased vocal intensity and the amplitude of both formants. F1 frequency consistently shifted upward under high-intensity broadband noise, while F2 shifts depended on vowel and noise type, shifting upward for /a/ and downward for /i/. Some patterns could not be explained by power spectra alone. Instead, they were better accounted for by frequency-specific masking effects, reflected in overlapping excitation patterns in the auditory spectral representation. These overlaps indicated reduced self-audibility in specific frequency bands, triggering compensatory adjustments. The findings highlight how auditory masking influences speech production, supporting a perceptually grounded model of auditory-motor control in noisy environments.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"1737-1750"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144992481","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}

Listeners judged the perceived distance of a frontal source simulated between 0.5 and 10 m in a room via headphones, with eyes closed in a soundproof booth. All stimuli were equalized in broadband received level. Source signals with different spectra (pink or white noise, speech) were tested. The results indicate similar variations in distance estimates with simulated distance for the three source types. While listeners might have combined different cues for their evaluations, if they were to have used a single cue, the results point to the direct-to-reverberant ratio (DRR) or the spectral balance/centroid. A systematic bias in distance estimates was also observed across source types: Reported distances were on average farthest for pink noise, closer for speech, and closest for white noise. The DRR and spectral balance account reasonably well for the differences between pink and white noises, but not for the differences between speech and noises. Overall, the DRR led to the highest correlation with the distance estimates.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"1947-1961"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030244","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}

Unfamiliar research indicated that the nonlinear interaction between acoustical transmitters plays a crucial role in the acoustic field formation of MPAs, however, the characteristics of such nonlinear interaction remain an underexplored area underlying the beam formation. This study investigates MPAs' acoustic beam using steerable Gaussian beam expansion under paraxial approximation. From the perspective of acoustic field structure, the mechanisms and parameter influence law on nonlinear coupling strength among distinct acoustical transmitters are elucidated. The transmitting array gains (TAGs) of MPAs are derived as a superposition of linear and coupling terms, and the enhancement effect of increasing array elements on TAG is analyzed. Furthermore, generation mechanisms of highly directional beams and vortex beams are explored. Controlling the phase difference at high frequencies as ±π/2 can exploit nonlinear coupling to achieve a narrower beam width than a conventional in-phase array. Adjusting the phase difference with azimuth angle enables the generation of vortex beam with an analysis of the orbital number and transmitters' number impacts. Experimental results validate the theoretical analysis of the nonlinear interaction characteristics, providing a robust physical foundation for the further manipulation of MPAs.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 3","pages":"2111-2129"},"PeriodicalIF":2.3,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145064907","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}
