Detection of string vibrations using home equipment

[DudasPL]

Hi

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.

Hi there,

Thank you for reaching out with your question about detecting string vibrations using home equipment. I can offer some suggestions for how you might approach this problem.

Firstly, you could try using a high-speed camera to visually capture the vibrations of the string. This would allow you to measure the time of decay more accurately than relying on sound detection. Alternatively, you could try using a laser or light sensor to detect the movement of the string.

Another option could be to use a more sensitive microphone or an accelerometer to measure the vibrations. These tools are designed specifically for detecting small movements and may be more effective in capturing the full duration of the string's vibrations.

It's also important to consider any external factors that may be affecting your measurements, such as background noise or interference. You may need to conduct your experiments in a controlled environment to ensure accurate results.

I hope these suggestions are helpful to you in your experiment. Good luck with your research!
