How can I find the sustain time of an electric guitar?

How can I find the sustaining time of an electric guitar? The influence of other components besides the strings can be neglected. I need it for my term paper.

Welcome to PF.

What reading have you been doing about this so far? What do you think the relevant equations would be?

Ummm . . . measure it? There are phone apps for analyzing sound.

It seems to me it must be related to the following formula:

but I don't know how to find the damping time of the damped oscillations. I haven't found the corresponding formulae

I need to find this theoretical

Maybe you could start with a list of the things that dissipate energy from a vibrating mass (a string in this case).

Or an on-line search for "Damping Factor".

Do you have a definition of sustain time?

It seems to me it must be related to the following formula:

Why?
What do you know about oscillating strings?
