Özet:
Bassoon is an instrument with double reed, belonging to the woodwind instruments family. Although it has an approximately 400 years history, it hasn't completed its development due to problems arising in the developmental process. Because producers have developed the instrument individually and a standard instrument didn't come up until the 19th century, it has led to looking for individual solutions. To play a bassoon, bassoon player should blow into bassoon reed and transmit the wind into the instrument. Specifications of bassoon reed directly affect the tone color of the instrument. Therefore, it is important to use a cane manufactured properly. Today, bassoon reed can be manufactured using natural and synthetic materials. Reeds manufactured from the “ArundoDonax” plant are mostly preferred by bassoon players. Organic reeds become unusable within 15-20 days due to the pressure of the lips on bassoon during play, spit, humidity and temperature of the air. The short lifetime of the organic reeds has led to the use of synthetic materials. A lifetime of the reeds manufactured from the synthetic material is 2 years, but it is not sufficient when providing tone and intonation. Therefore, it is a necessity to make a scientific comparison of two reeds for synthetic canes having tone quality of organic reeds. In this study, structural and acoustic differences between organic and synthetic bassoon reeds were analyzed and it was aimed to reveal the differences quantitatively. Within the scope of the study, cane characterization was performed between synthetic reeds obtained from the market, thermoplastic matrix composite reeds manufactured by hot pressing and traditional organic reeds. For this purpose, material specifications such as elastic modulus, density, damping, hardness, surface roughness were determined, and acoustic specifications of the reed were analyzed. In consequence of the matter of the project, researchers from different areas came together. In the research team of the project there will be researchers from conservatory, mechanical engineering and material science and engineering disciplines. This research project (119M49) was funded by Scientific and Technological Research Council of Turkey (TÜBİTAK).
