Detection of string vibrations using home equipment

  1. Nov 25, 2009 #1

    I have a problem in detecting whether string is vibrating or not. I'm going to conduct experiment which will investigate impact of different factors on time of decaying of guitar's string oscillations but I have no idea how to measure when oscillations stopped. Acoustic method doesn't work well, I can detect sound using microphone only for ~6 sec, while string is vibrating ~20sec. Any other ideas?

    Perhaps you can try using a video camera and a strobe light (of known frequency) to detect the vibrations.
