Acoustic properties of textile materials enabling bel canto singing Application Research on sound insulation and sound quality optimization

Bel canto singing has strict requirements for the sound insulation effect and sound quality performance of the sound field environment, and textile materials with the advantages of light weight, flexibility and strong designability have become the ideal candidate materials for optimizing the singing sound field. This paper systematically explores the application value of acoustic characteristics of textile materials in Bel canto singing, focusing on the two core objectives of sound insulation and noise reduction and sound quality optimization, and constructs a complete research framework of "material selection - structural design - performance verification - scene application". Firstly, based on the acoustic theory and the acoustic requirements of bel canto singing, the key acoustic indicators (sound insulation loss, sound absorption coefficient, sound diffusion coefficient, etc.) are defined; Secondly, typical textile materials such as cotton, hemp, wool and polyester fiber were selected, and multiple groups of samples were prepared and their acoustic properties were tested by changing the fiber type, fabric structure, thickness and other parameters; Moreover, combining with the range of bel canto singing (200hz-1500hz), the matching law between the acoustic characteristics of the material and the singing sound quality is analyzed; Finally, the application effect of textile materials in concert hall, recording studio, family practice room and other scenes is verified through simulated singing scenes and field experiments.
