A while ago, I posted a question about musicians with weaponized instruments guarding a palace. I thought it would be interesting if they also had access to some sort of poison that they could use to poison someone (with poison in the drink for instance), if secrecy was more necessary. I came up with this idea of the musicians playing music to the poison-making microorganisms to grow them. Now, I also found [this][1] interesting question, with an answer stating various energy sources (pressure, heat, etc.) that could be transformed to give usable chemical energy to an organism. However, specifically sound energy was not mentioned. **Could sound waves be theoretically transformed into energy for a microorganism for the purpose of cultivating these microorganisms? How would this work?** [1]: https://worldbuilding.stackexchange.com/questions/46564/how-could-non-photosynthetic-non-chemotrophic-autotrophs-create-usable-energy
