You are right, but know that it can be hard for someone to judge claims.
And to answer OP: I’d say try to read qualitative, well established newspapers. They often have various overview articles and if you read articles from a couple of them then you should get a diverse view
What you can do, and is probably the best way to get this to work, is tackle this with machine learning. You will need lots sound samples of rocks, with details of the rock, and feed them to some (probably deep learning) model.
Speech mimicking with AI has shown we are able to mimick voices, so I think a similar approach would work for rocks. Probably need some tuning and a bit different architecture for nice results since the application differs a bit.
It will of course be an approximation, but that is any calculation. Since all models are wrong, but some are less wrong than others.
Nah I disagree, people can also send articles to friends
