Indications of Vibratory Stress Relief in New Guitars

D.P. Hess

Abstract

This paper presents frequency response measurements from new acoustic guitars before and after a 168-hour exposure to broadband vibration. The data shows changes consistent with that observed and used to indicate effective vibratory stress relief in other applications. These changes occur around the natural frequencies of the response peaks and include increases in magnitude of the peaks and shifts in the peaks to lower frequencies. In addition to presenting this data, a goal of this paper is to increase awareness of the physical mechanisms associated with these changes by referencing and briefly describing the relevant literature.
