Twenty years later, the standard has been revised again as ISO 226:2023. One motivation for the revision was to reflect the lowering of the threshold of hearing at 20 Hz by 0.4 dB in ISO 389-7:2019. In addition, the following two points of substance were revised: (1) implementation of the power exponent relating loudness perception to physical intensity formulated in an academic paper published in 2004, which describes the derivation of ELLCs relating to ISO 226:2003, and (2) adoption of mathematical expressions that preserve the appropriate number of significant digits. In this review, the process of the revision and the technical details of the changes are described. The differences from the 2003 edition are only 0.6 dB at most, and the 2023 standard can be regarded as the same as the 2003 edition in terms of practical use.","PeriodicalId":46068,"journal":{"name":"Acoustical Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135158535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yamakawa","doi":"10.1250/ast.43.322","DOIUrl":"https://doi.org/10.1250/ast.43.322","url":null,"abstract":": Several previous studies in speech production obtained a boundary of two phoneme categories by an exhaustive search for the ‘‘optimal boundary’’ that provides the best phoneme classification on an acoustic dimension such as voice onset time. However, they used this method without confirming its accuracy in estimating the true boundary. The present study examined this accuracy by conducting a Monte Carlo simulation under several conditions of the means and variances of two phoneme categories. The results revealed that, compared with the statistically estimated boundary, the ‘‘optimal boundary’’ tended to have bigger root mean square errors from the true category boundary. This finding indicates that the ‘‘optimal boundary’’ is less accurate than the statistically estimated boundary for estimating the true boundary. Our study considers the limitations of the previous method and recommends a statistically estimated boundary in future investigations.","PeriodicalId":46068,"journal":{"name":"Acoustical Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75061777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patitsas","doi":"10.1250/ast.43.297","DOIUrl":"https://doi.org/10.1250/ast.43.297","url":null,"abstract":": It is verified that the source of the acoustic emissions when beach sand or other squeaky grains are stepped on or impacted by a pestle lies in a thin shear band directly under the pestle. The grain layers in this band slide one over another at a slow creepy pace giving rise to energy transfer, via the stick-slip effect, from the impacting pestle to the elastic vibrations in the shear bands at the grain contact areas. In turn, this vibration energy feeds the elastic modes of vibration along the vertical grain columns or equivalently, the elastic modes of vibration in the shear band under the pestle comprising the vibrating columns, with dominant frequency in the range of 1,000 Hz. In search of an explanation of the acoustic emissions when booming dune sand is pushed by a blade or is freely avalanching, we adopt the concept of the collision shear band, where, due to the high degree of fluidity of the sand mass, the grain layers slide one over another at a brisk pace so that the average collision frequency between grains in two adjacent grain layers defines the dominant frequency of the acoustic emission in the range of 100 Hz.","PeriodicalId":46068,"journal":{"name":"Acoustical Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80212942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we developed a vibration source that generates an elliptical locus using a single longitudinal vibration transducer. Although vibration sources with an elliptical locus have been reported previously, they were designed using the equivalent transmission line method. In this paper, we used the finite element method to elliptical vibration source design, and we fabricated a vibration source and measured its characteristics. Bringing the resonance frequencies of the longitudinal and torsional vibration closer together allowed vibration with an elliptical locus to be obtained at a single frequency.","PeriodicalId":46068,"journal":{"name":"Acoustical Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80651116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
