Harmonic Structure of an Aging Guitar String
Jont B. Allen · The Journal of the Acoustical Society of America · 1974
By application of various signal processing means, namely FFT, linear estimation, and digital filtering, impulse responses of new and old guitar strings were analyzed to determine the important differences. These measurements were compared to the theoretical results derived from the generalized string equation operator ε∇4+∇2+k2, using appropriate boundary conditions. Results are discussed and synthetically generated samples will be played.
