Measure the speed of sound in the sand

Projects General Guidance

Hello,
I would like to measure the speed of sound in the sand.
To do this, I bought an ultrasound receiver (Waterproof JSN-SR04T) and a transducer that has a power of 60W (I don't know if it will be enough).
Do you think it will be possible to measure the speed of sound?

We did this on my last job. We used geophones to measure the propagation rate of a shockwave in soil. So, yes, it's done every day.

You might find that only a limited frequency range will get much range in sand.

Is this sand wet or dry? Does it contain objects much larger than a grain of sand?

Isn't sand non-Newtonian? Quicksand is.
