A simplified and controllable model of mode coupling for addressing nonlinear phenomena in sound synthesis processes

Abstract This paper introduces a simplified and controllable model for mode coupling in the context of modal synthesis.The model employs efficient coupled filters for sound synthesis purposes, intended to emulate the generation of sounds radiated by sources under strongly nonlinear conditions.Such filters generate tonal components in an interdepend

A Phononic Crystal-Based High Frequency Rheometer

Dynamic Mechanical Analysis (DMA) allows for the measurement of the complex shear modulus of an elastomer.Measurements at frequencies above the frequency range of the device can be reached thanks to the Time–Temperature Equivalence principle.Yet, frequencies higher than a TMG few kHz are not attainable.Here, we propose a method exploiting the
