Yes, I think it might have been more straightforward to say “Researchers observe stationary Hawking radiation in ‘acoustic black hole’” or something to clarify to laypeople that this is a mathematically analogous but physically very different experiment. I don’t think it’s too difficult to conceptualize that sound waves behave similarly to light waves and that properties of black holes can be “simulated” with sound.
