Article A Modeling Approach for Designing New Acoustic Materials(Gazi Univ, 2024) Koçyiğit, Filiz Bal; Köse, Ercan; Buluklu, Hatice Mehtap; Bal Kocyigit, FilizIn this study, mathematical modeling design based on Sound Transmission Loss measurement results of new acoustic material samples with natural content was carried out. Using the test samples in question, transfer function of acoustic materials based on electronic filter circuit design and a transition design method for the production of new acoustic materials by utilizing the transfer function is presented. Based on the experimental results of the test samples, it is the most suitable low-pass filter structure for the proposed design. In this study, active Sallen-Key low-pass filter structure is preferred and used. Sound Transmission Losses in dB (decibels) of acoustic samples were obtained experimentally for 500, 1000, 2000 and 4000 Hz. fundamental frequencies in the literature. Based on these data, transfer function simulation suppression gain results were obtained in TINA-TI program, active filter circuit designed, and MATLAB program. When the other results were compared in the experimental results, it was seen that very close values were obtained. It has been demonstrated that the proposed method can be used effectively in the design and examination of new acoustic materials.Article Citation - WoS: 2Citation - Scopus: 3Low-Cost Alpha Cabin Like Test Box Proposal for the Development of New Acoustic Sound Insulation Materials(Gazi Univ, 2023) Koçyiğit, Filiz Bal; Köse, Ercan; Buluklu, Hatice Mehtap; Bal Kocyigit, FilizExperimental criteria for sound insulation material recommendation and design have an important share in indoor acoustic control. Among these criteria, laboratories with devices such as impedance tubes, alpha cabins and reverberation rooms used to measure and analyze parameters such as sound transmission loss and sound absorption coefficient have been investigated. In literature, it has been observed that there are studies on acoustic materials and the tests applied to these materials, but the application is more limited. According to research data, an Alpha Cabin model system design that can be used to develop new types of acoustic sound materials has been proposed. In addition to the fact that a large number of experimental measurements can be performed at lower costs using the designed Alpha Cabin model system, many tests can be performed easily for different material designs in a very short time. To perform these tests, the Alpha Cabin system has been designed based on noise and sound insulation. For example, floating flooring, ribbed connection, and so on. Afterward, different insulation materials were used for insulation purposes and standards were achieved. The Alpha Cabin test system, which was designed and developed, overlaps the experimental and theoretical data for 500, 2000, and 4000 Hz when compared with the values of 29.1 dB for 500 Hz, 38.6 dB for 2000 Hz, and 49 dB for 4000 Hz measured in the Acoustic Facade Panel Test Room, and it has been observed that it can be used in the development of new sound insulation materials.Article Bibliometric Analysis of Publications on Stapedius Muscle(Pera Yayincilik Hizmetleri, 2024) Sever, Sinem Nur; Sen, Esra; Turhan, BegümhanObjective: The clinical importance of the stapedius muscle has been particularly emphasized in several publications. The purpose of this study is to bibliometrically analyze all publications on the stapedius muscle and to determine research trends related to this muscle. Methods: The publications related to the stapedius muscle were identified by the Web of Science database. A total of 548 publications were discovered throughout the literature review. Bibliometric techniques were employed to analyze the identified publications (VOSviewer Version 1.6.13). Results: The first studies were conducted in the 1980s. The highest number of publications related to the stapedius muscle was in 2020 (22 studies), while the lowest was in 1985 (2 studies). Most of the publications (90.11%) were written in English. The USA was the most prolific nation, with John J. Guinan having written the most articles on the stapedius muscle. Harvard University was also the most prolific institution. Conclusion: The findings demonstrated the researchers’ interest in the stapedius muscle and offered quantifiable information regarding the muscle’s position within the scientific domain. Recent years have seen an increase in studies on this topic. To the best of our knowledge, it can be said that this study is the first bibliometric analysis on the stapedius muscle.
