Characteristic analysis emphasizing super- harmonic components of vibrations and radiated sound due to the geometric nonlinearity of curved plates and its application to improving conversational recognition in the elderly
In curved plates, as the vibration amplitude increases, the strain from bending deformation and the strain from in-plane deformation become coupled. This is known to generate vibrations or radiated sound with super-harmonic components different from the input frequency. We report on the generation of super-harmonic components and chaotic vibrations obtained through theoretical analysis of curved plates. We also discuss the prospect of applying this characteristic to improve speech recognition in the elderly by emphasizing consonant frequencies. Furthermore, we consider collaboration with AI.
