Regulation of acoustic properties in nanocomposite porous musical structures by nanoparticles and their application in sound harmony

The role of nanoparticles in improving acoustic properties of materials used in the musical structures based on nanocomposite porous materials is explored in this study. We integrate nanoparticles into a nanocomposite porous framework to investigate their effect on the sound absorption and acoustic properties, on the tonal quality of the sound. Micromechanical model is used to evaluate the effective nanocomposite properties and the structural behavior is analyzed by means of the mathematical modeling. We derive the governing equations of sound propagation and acoustic properties through energy relations. We assess the acoustic performance due to variation of porosity levels, nanoparticle concentration and geometric factors using the numerical method. An increase in the nanoparticle content was found to increase sound absorption and to improve harmonic stability significantly, while controlled porosity can fine tune resonance characteristics. The discovery of these findings suggests ways to design advanced musical structures having higher acoustic harmony and can lead to new developments in the design and construction of instruments.
