Andy Culpepper -> RE: Objection "Sustained" (Aug. 11 2010 22:51:39)

OK if anybody is interested here is some data I just took. I measured 3 guitars, 2 flamencos and a classical, by striking certain notes or chords and measuring the sustain with a stopwatch. I started the watch when I struck the notes and stopped when all sound died away completely, including fundamentals, overtones, harmonics, etc. I did each test 3 times, trying to strike the string equally hard each time, and averaged the results into the final number. To damp strings I used a piece of sponge inserted under the strings at the 19th fret. Here goes: Guitar #1: Spruce top blanca made by me 1. Low E string, other strings open: 10 seconds 2. Low E string, other strings muted: 11.5 3. All strings open in a chord (none fretted): 12 4. High E string, others open: 8 5. High E string, others muted: 4.5 Guitar #2: Cedar top classical made by me (Indian RW, much heavier) 1. Low E string, other strings open: 10.5 2. Low E string, other strings muted: 11 3. All strings open in a chord (none fretted): 11 4. High E string, others open: 9 5. High E string, others muted: 4.5 Guitar #3: Cedar top blanca, made by my luthery teacher (this is a guitar that I have always thought of as having a lot of sustain, although it's very light) 1. Low E string, other strings open: 12 2. Low E string, other strings muted: 10 3. All strings open in a chord (none fretted): 12 4. High E string, others open: 8.5 5. High E string, others muted: 4.5 The results kind of surprised me. All the guitars are within 1.5 seconds of each other in every category, and my classical appears to have the lowest overall sustain,[:-] although the high E sustains longest ... Another odd thing was that my on my 2 guitars, the low E string actually sustained longer with the other strings MUTED! Although the high E had consistently MUCH less sustain with the others muted.
