 1 Satoshi Ishikawa, Ataru Matsuo, Yuta Akayama, Shinya Kijimoto, Coupled analysis of two-dimensional acoustic and membrane vibration by concentrated mass modelProposal of spurious mode elimination model, Advances in Mechanical Engineering, https://doi.org/10.1177/1687814017746512, 9, 12, 2017.12, When using the finite element method for structural–acoustic coupled analysis, the mass and stiffness matrices are not symmetric because the acoustic space is described by sound pressure and the structure is described by displacement. Therefore, eigenvalue analysis requires a long computational time. In this article, we proposed concentrated mass models for performing structural–acoustic coupled analysis. The advantage of this model is that the mass and stiffness matrices become symmetric because both the acoustic space and the membrane are described by the displacement of the mass points. Furthermore, our models do not generate spurious modes and zero eigenvalues that arise in finite element method whose variable is displacement in acoustic space. To validate the proposed models, the natural frequency obtained using the concentrated mass models is compared with the natural frequency found using finite element method. These results are in good agreement, and spurious modes and zero eigenvalues are not generated in the proposed model whose variables are sound pressure. Furthermore, we compare the proposed model with finite element method in terms of the calculation time required for the eigenvalue analysis. Because the matrices of the proposed models are symmetric, these eigenvalue analyses are faster than that of finite element method, whose matrices are asymmetric. Therefore, we conclude that the proposed model is valid for coupled analysis of a two-dimensional acoustic space and membrane vibration and that it is superior to finite element method in terms of calculation time.. 2 Xun Wang, Yousuke Koba, Satoshi Ishikawa, Shinya Kijimoto, Hybrid active noise barrier with sound masking in open-plan offices, Noise Control Engineering Journal, https://doi.org/10.3397/1/376389, 64, 3, 403-415, 2016.05, This paper presents a small-typed active noise barrier (ANB) with sound masking techniques for alleviating the noise problem and protecting the speech privacy in open-plan offices. This soundproof system reduces and masks the undesired sound simultaneously so that lower level of the masker is required to achieve the sound masking effect, comparing with the conventional sound masking systems. First, a real-time experiment to verify the noise attenuation performance of the proposed system for practical application has been conducted in a real office room. In the experiment, the influence of background noise on the system performance has also been investigated. The experiment results show that 3-8 dB active noise attenuation can be achieved behind the ANB in an office room. Moreover, in order to select an appropriate masker for the sound masking part of the system, several maskers have been compared and investigated by listening experiments. The results suggest that the stationary maskers are more suitable for the sound masking in offices by considering the sound masking performance and the annoyance of the maskers comprehensively.. 3 Xun Wang, Takayuki Satake, Yosuke Koba, Satoshi Ishikawa, Shinya Kijimoto, Active reduction of the two-way diffraction from a noise barrier by using feedforward control, 45th International Congress and Exposition on Noise Control Engineering: Towards a Quieter Future, INTER-NOISE 2016Proceedings of the INTER-NOISE 2016 - 45th International Congress and Exposition on Noise Control Engineering: Towards a Quieter Future, 576-586, 2016.08, This paper develops a feedforward (FF) structure based active noise control (ANC) system that reduces the two-way diffraction from an office partition with the aim of actively creating isolated acoustic domains in open-plan offices. The FF-ANC system can only reduce the noise downstream of the reference sensor due to the causality requirement. Therefore, a coupled FF control structure is proposed to realize the reduction of two-way diffraction. This system applies a two-source loudspeaker array as the control source, and two microphones as the reference and error sensors. The directivity of the loudspeaker array is controlled to emit the control sound only into the corresponding control area. In comparison with the preceding active diffraction reducing systems, using a directivity controlled loudspeaker array can generate an absorptive acoustic boundary rather than a reflective boundary on the diffracting edge, which can isolate the acoustic environment without adding reverberation in a room. The effectiveness of the proposed system is verified by computer simulations.. 4 王循, 木庭洋介, 石川 諭, 雉本 信哉, ハイブリッドANCシステムを用いた能動的遮音壁(ロバスト性能を確保できる適応型フィードバックANCシステムの提案及び適用), 日本機械学会, http://doi.org/10.1299/transjsme.15-00532, Vol. 82, No. 835, p. 15-00532, 2016.02. 5 KIJIMOTO Shinya, ISHIKAWA Satoshi, WANG Xun, KOBA Yosuke, An adaptive method for designing a robust IMC structured feedback active noise controller, Noise Control Engineering Journal, http://dx.doi.org/10.3397/1/376344, Vol. 63, No. 6, ４９６-５０７, 2015.11. 6 王循, 木庭洋介, 石川 諭, 雉本 信哉, ハイブリッドANCシステムを用いた能動的遮音壁(ウォーターベッド効果による増音の抑制及び各種音場における減音効果の考察), 日本機械学会, http://doi.org/10.1299/transjsme.15-00064, Vol. 81, No. 827, p. 15-00064, 2015.07. 7 石川 諭, 雉本 信哉, 木庭洋介, 藤原 圭佑, 集中系モデルを用いた押込試験による生体柔軟性計測技術の開発, 日本機械学会論文集, http://doi.org/10.1299/transjsme.14-00480, 81, 823, 2015.03. 8 久野翔太郎, 石川 諭, 雉本 信哉, 木庭洋介, 集中系モデルを用いた状態フィードバックに基づく能動騒音制御（音響機器を含む1次元音響空間のモデルベース制御）, 日本機械学会論文集, http://doi.org/10.1299/transjsme.14-00485, 81, 822, 2015.02. 9 王循, 木庭洋介, 石川 諭, 雉本 信哉, ハイブリッドANCシステムを用いた能動的遮音壁, 日本機械学会論文集C編, http://doi.org/10.1299/transjsme.2014dr0165, 80, 814, 2014.06. 10 WANG Xun, KOBA Yosuke, ISHIKAWA Satoshi, KIJIMOTO Shinya, Hybrid active noise barrier with sound masking, Inter Noise 2014, 2014.11. 11 石川 諭, 雉本 信哉, 木庭洋介, 大脇 亮磨, 森 裕樹, 集中系モデルによる2次元音響解析, 日本機械学会論文集B編, 79, 801, 744-748, 2013.05. 12 SUGIKI Shohei, ISHIKAWA Satoshi, KIJIMOTO Shinya, KOBA Yosuke, Simulation of Speech Production by Concentrated Mass Model, Inter Noise 2013, Paper No. 1122, 2013.09. 13 ISHIKAWA Satoshi, KIJIMOTO Shinya, KOBA Yosuke, OWAKI Ryoma, MORI Yuki, Two-Dimensional Acoustic Analysis by Concentrated Mass Model, Inter Noise 2013, Paper No. 1116, 2013.09. 14 嘉村俊一, 木庭洋介, 松田 浩一, 雉本 信哉, 周波数領域適応アルゴリズムを用いた衝撃音の能動制御, 日本機械学会論文集C編, 78, 789, 1655-1662, 2012.05. 15 大野佳子, 池田生馬, 木庭洋介, 松田 浩一, 雉本 信哉, ステップサイズベクトルを用いた評価点移動時の能動音響制御, 日本機械学会論文集C編, 78, 789, 1670-1679, 2012.05. 16 Yoshiko Ohno, Yosuke Koba, ISHIKAWA Satoshi, Shinya Kijimoto, ACTIVE NOISE CONTROL FOR A MOVING EVALUATION POINT USING STEPSIZE VECTOR AND SECONDARY PATH INTERPOLATION, MJIIT-JUC Joint Symposium 2012, 2012.11. 17 Yasuhiro Shimada, ISHIKAWA Satoshi, Shinya Kijimoto, DEVELOPMENT IN MEASUREMENT METHOD AND ANALYSIS MODEL OF LIVING BODY, MJIIT-JUC Joint Symposium 2012, 2012.11. 18 Xun WANG, Shinya KIJIMOTO, Yosuke KOBA and Koichi MATSUDA, Noise Barrier Using Feedback Active Noise Control, The 40th International Congress and Exposition on Noise Control Engineering (INTER-NOISE 2011), TS-6, SS33, 2011.09. 19 Koichi MATSUDA and Shinya KIJIMOTO, Reaction Disturbance Cancellation for a Magnetically Levitated Ladder Arm of Clean-Room Robot, Proc. of the 36th Annual Conference of the IEEE Industrial Electronics Society, pp. 1590-1596, 2010., pp. 1590-1596, 2010., 2010.01. 20 Koichi MATSUDA and Shinya KIJIMOTO, Reaction Disturbance Cancellation for a Magnetically Levitated Ladder Arm of Clean-Room Robot, Proc. of the 36th Annual Conference of the IEEE Industrial Electronics Society, pp. 1590-1596, 2010., pp. 1590-1596, 2010., 2010.01. 21 池田生馬，雉本信哉，松田浩一, 空間の音響モード特性を考慮した広帯域能動的音響制御, 日本機械学会論文集C編, 76, 765, 1265-1270, 2010.05. 22 Ikuma IKEDA, Shinya KIJIMOTO, Koichi MATSUDA, Yosuke KOBA and Keitaro KAGEYAMA, Active Noise Control Using Position of Evaluation Point, Journal of System Design and Dynamics, 4, 753, 1421--1427, Special Issue on D&D2008, Paper No. T2-08-0860, 2009.05. 23 池田生馬，雉本信哉，松田浩一，木庭洋介，景山慶太郎, 評価点の位置情報を利用した3 次元能動的音響制御, 日本機械学会論文集C編, 75, 753, 1421--1427, 2009.05. 24 大窪貴宏，雉本信哉，松田浩一，木庭洋介, 音響信号を利用した水素漏洩検出法, 日本機械学会論文集, C編，75巻，752号，pp.912 -
