Plate reverberators with adjustable features – concept of study and test stand
Abstract:
Mechanical vibration of plates have applications in many fields of science and industry including synthesis of artificial reverberation – one of the most important signal processors in audio engineering. The paper presents a concept for study and measurements of reverberating plates that contains an initial numerical solution with a goal of predicting behaviours of the vibrating plate as its response for physically affecting its vibration. The concept also considers experimental measurements of selected simplified solutions as well as their comparison with numerical simulation. In addition the paper contains evidence for perceptible differences between audio signals obtained from the initial experiments, which suggests the viability of adjustable mechanical reverberation mechanism. Moreover, the paper includes concept for test stand for experimental study of reverberating plates in order to achieve signals differing in perceptually significant way. The test stand and study will allow to increase knowledge of vibrating plates as parts of plate reverberation devices.
