An audio analogue to Hawking blackhole radiation

Rate this topic

Recommended Posts

This is a nice summary of a paper that appears in today's Nature




Briefly, the experimentalists created a Bose (integer spin particle, not the headphone/speaker fraudsters) condensate sonic blackhole analogue that allowed demonstration of Hawking radiation with phonons.




Do facts matter?

This is something. 

Should we be afraid of sonic black holes aka dumb holes ?


The man that hath no music in himself, nor is not moved with concord of sweet sounds, is fit for treasons, stratagems, and spoils. The motions of his spirit are dull as night, and his affections dark as Erebus. Let no such man be trusted. Mark the music.

Interesting.  Not sure what you can do with the analogous sonic system to prove things tho...

"The overwhelming majority [of audiophiles] have very little knowledge, if any, about the most basic principles and operating characteristics of audio equipment. They often base their purchasing decisions on hearsay, and the preaching of media sages. Unfortunately, because of commercial considerations, much information is rooted in increasing revenue, not in assisting the audiophile. It seems as if the only requirements for becoming an "authority" in the world of audio is a keyboard."

-- Bruce Rozenblit of Transcendent Sound
