Thanks! could it be that sound wave is faster in cement than in wood? how about their intensities?

I'm not sure what kind of metal it is but it is mostly used in constructions and the wood is the one used in making furnitures, for the cement ordinary cement only. How could i measure their speed? thanks :>

Which one do you think does a sound wave travel faster ?How can I experiment on this? Thanks :)
