This work investigates the application of coupled annular nanoplates in musical instruments, with enhanced sound absorption and precise harmonic synchronization, using an educational framework. In this approach, the surface couple stress theory has been used in order to investigate controllable in-phase and out-of-phase vibrations by using a viscoelastic substrate between the nanoplates, possibly providing a new degree of freedom for affecting the sound quality and acoustic resonance in instrument design. With the consideration of size-dependen...
