With minor adjustments, the method can also capture slower cortical auditory evoked potentials (CAEPs). CAEPs have not been previously described in bats but are often used in large animals and humans to study cortical signal processing. Here, we describe two late peaks in the bat (Tadarida brasiliensis) auditory evoked potential waveform that appear cortical in origin. The first deflection (P1) peaked at 23 ms and showed the same onset (∼10 ms) and duration (∼20 ms) as ensemble neuronal activity in the auditory cortex under matched conditions. A second, smaller wave (P2) peaked at 37 ms, correlating with evoked activity in a secondary auditory region known as the frontal auditory field. Both peaks varied in amplitude and timing depending on acoustic stimulus properties. Notably, P1 was reduced at presentation rates above 8 Hz, consistent with predicted effects of cortical forward suppression. These findings demonstrate that robust CAEPs can be non-invasively recorded in bats and carry information about stimulus features and underlying neural mechanisms.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 4","pages":"3390-3399"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145355175","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 address the problem, this study has investigated the characteristics of the target echo interference observed on the two-dimensional (frequency and target range) intensity plane, focusing on depth estimation applications in the reliable acoustic path environment. We first establish a ray-based echo interference model integrated with highlight scattering, decomposing the intensity plane into propagation interference (related to target depth), scattering interference (linked to target size), and cross-term components. Second, an f-warping transformation is proposed to resample the intensity plane. By straightening the originally curved propagation interference, it ensures that the inverse Fourier transform of the warped intensity plane exhibits a constant time delay. Finally, a hybrid framework combines time-delay matching with multi-frame stability assessment, utilizing adaptive weighting to suppress scattering interference while preserving propagation-related features. Simulations and experimental data have been used to validate the depth estimation method, and the errors for multiple sets of experimental data are all under 8% of the real target depth.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 4","pages":"3440-3455"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145355183","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}

Non-invasive techniques are essential for monitoring vital signs and indirectly measuring brain activity. This study evaluates an air-ultrasound technique for non-contact measurement of HR and HRV. We designed a system to capture skin motions related to cardiac activity, with displacements in the micrometer range. The study aimed to improve the accuracy of cardiac parameter measurement over previous methods by including respiratory tracking. The air-ultrasound method was tested in four young adult males, showing mean absolute errors in interbeat intervals compared to electrocardiogram R-R intervals, ranging from 1.5 to 11 ms, affected by individual variability and conditions. Incorporating respiratory phase information reduced errors by about 30%. Comparable or superior accuracy to contact methods like pulse oximetry, ballistocardiography, and seismocardiography was achieved with a 0.5-meter stand-off. Despite a limited, homogeneous sample in age, sex, and body mass index, the findings show significant variability in skin motion waveforms, necessitating adaptive strategies. The results indicate that this air-ultrasound technique is promising for neuroscientific, behavioral, and clinical applications, where non-contact cardiac monitoring is advantageous.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 4","pages":"2979-2994"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145301556","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}

During bone conduction (BC) stimulation, these pressures exhibit pronounced variability and similar magnitudes in the two scalae, making their interpretation challenging. These characteristics arise from the vibration of the entire inner ear and interactions between the different BC mechanisms. Using fundamental acoustic principles, we derive characteristics of intracochlear pressure distributions driven by fluid inertial effects from rigid body vibration of the inner ear. Our analysis shows that the vibration at a spatially uniform velocity in a single direction results in (1) proportionality of the pressure to stimulation velocity and frequency, (2) a linear pressure variation along the vibration direction, (3) uniform pressure in planes perpendicular to the motion, and (4) minimum pressure at a plane approximately aligned with the round window centroid. The superposition principle allows the extension of these results to any complex-valued amplitude vector of rigid body translation. The findings provide insights into the variability of experimental intracochlear sound pressure measurements and enhance the understanding of the interactions between the mechanisms involved in BC hearing.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 4","pages":"3006-3016"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145301570","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 long, rambling warble song of male budgerigars is acoustically complex and composed of a number of distinct elements uttered in streams lasting several minutes, usually accompanied by various courtship behaviors, such as head bobbing and beak touching. Recent work has shown that warble song may have a sequential structure, or patterned repetition of elements. This raises questions as to whether budgerigars can detect changes in natural warble streams and to what extent these capabilities are specific to conspecific song. Here, this study examined the perception of long bouts of warble song from male budgerigars. Using operant conditioning and a psychophysical procedure, the study probed the limits of the birds' ability to detect various changes in new and familiar sequences of warble elements. The study shows that budgerigars can detect sequence changes in short unfamiliar sequences of warble and in much longer segments of familiar warble sequences.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 4","pages":"2863-2868"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145280555","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}

Given the importance of the inharmonicity coefficient in tone synthesis and analysis of stringed musical instruments, a precise and automated estimation method is essential across the entire instrument register. To address this, a modification of the partial frequency deviation (PFD) algorithm was proposed, aimed at identifying and excluding phantom partials during inharmonicity estimation. The modified PFD algorithm was evaluated using a set of synthesized signals with systematically varied parameters, as well as a collection of recorded concert harp tones. Experimental results demonstrated that for 64% of real tones, the modified PFD algorithm yielded more accurate inharmonicity coefficient estimates compared to the original PFD algorithm, with improvements reaching up to 88.5% for certain tones. The accuracy of the inharmonicity coefficient estimation was found to depend primarily on the ratio between the number of phantom partials and the total number of partials used for estimation, as well as the spectral position and grouping of these phantom partials.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 4","pages":"3187-3202"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145337166","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}

Sentence recognition was measured in speech-spectrum noise (SSN) and amplitude-modulated noise (AMN) among two groups of normal-hearing listeners. Signals were low-pass filtered and five-channel noise vocoded, presented dichotically for bimodal and monaurally for electric-acoustic stimulation (EAS) simulation. Temporal misalignment was implemented by introducing delays between simulated electric and acoustic signals (0, ±5, ± 10, ±15, ±30 ms), with positive delays (group 1) simulating the electric-leading conditions and vice versa (group 2). A three-way interaction indicated that delay effects depended jointly on the listening condition and noise type. Under AMN, the slope of delay was significantly steeper in the EAS condition compared to the bimodal condition. In the EAS condition, the slope of delay was significantly steeper under AMN than under SSN. In addition, the two-way interaction between the lead-lag relationship and delay indicated that the slope of delay was steeper when the simulated electric signal lagged the acoustic signal. These findings suggest that compensating for temporal misalignment between acoustic and electric signals may help enhance speech recognition, particularly under conditions where the impact of delay is greater.","PeriodicalId":17168,"journal":{"name":"Journal of the Acoustical Society of America","volume":"158 4","pages":"3378-3389"},"PeriodicalIF":2.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145346037","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}
