# Measuring distance a sound wave travels

I would like to be able to measure the distance a sound wave travels. This is for a violin bridge and what I would like to do is apply a frequency corresponding to the frequency the string (196 hz for the g string) and determine the distance the wave traveled to get to the foot of the bridge. Is there a method to do this?

How are you generating this frequency?

The answer to your question is: 'with a ruler' between the bridge and the nut or, possibly from the bow to the bridge. But I don't think that's what you actually want to know. Could you elaborate?

No it is not. I want to know how far the vibration travels from the G string ,for example, to the bass foot of the bridge and how far the same vibration travels to the treble foot. it is not as simple as using a ruler as there are incisions and holes in the bridge that are there to slow the vibrations down. The goal here is to get the vibration to the feet at the same time from all strings being played.

paisiello2,
Not sure at this point. Thought that would be the easier of the two problems to solve. Thinking electronic generation, but open to suggestions

It may be that you mean "how fast" and not how far? It seems that you know both where the wave starts and where it ends. So if you really want to know how far, sophiecentaur's answer is it. No holes or incisions matter.
