Several different kinds of "STRESSED RESONATORS" are investigated. With the installation of a sound post a violin’s tone enriched not only in physical amplitude but also the autocorrelation function parameters and inter aural cross correlation parameters are “amplified”. The measurement for a simple model system with single STRESSED RESONATOR shows various possibilities in this direction.

Key words: violin, sound post, stress, resonator, autocorrelation function (ACF), Interaural cross-correlation function (IACF)
