The latest analog black hole experiment done in Israel has extracted phonic energy as Hawking radiation from the vacuum.

These can be built from things that produce waves, such as fluid and sound waves in a special tank <https://www.youtube.com/watch?v=kOnoYQchHFw>, from Bose-Einstein condensates <https://royalsocietypublishing.org/doi/full/10.1098/rsta.2008.0062>, or from light contained in optical fibre. Does that help?
