What does the sun sound like?

Hang on, I've got a cat in this box; I'll see if he heard anything. |

What does the sun sound like?
Since your original question was "What does the sun sound like?" I think it's fair to exclude sound outside the range of human hearing. After all, most of the sound all around us here on the Earth is similarly outside our hearing range. It's sound, but it doesn't sound like anything at all. That brings up that silly-assed high school English class question: "If a tree in a forest falls over but nobody is around to hear it, did it make a sound?". Answer is in your definition of the word "sound". Some definitions involve a set of human ears... As the "surface" of the Sun is constantly churning over (like as in a pot of boiling water), it probably sounds somewhat like the rushing noise from a smokestack spewing lots of pollution, or like a waterfall. Or a nuke bomb just after it goes off. Probably extremely loud. I probably remember this incorrectly, but doesn't the Sun's corona get superheated from acoustic energy (sound)? |

But by far the most common definition is simply compressional waves traveling in some medium, without regard to human ears, especially in the scientific context I assume given the forums where the question was asked. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

What does the sun sound like?
Just for the fun of it once, a friend and I got a large 10ft spherical dish and
put a microphone at the focus, hook up an amp and a recorder and pointed it at storms approaching. It really was quite a kick. Thunder was unreal! We gave the tape to a guy who was producing a movie and he loved it. One warm summer night we hooked it up and pointed at nearby woods and the grass - have you ever heard crickets at 120 db! ? I swear you could almost hear worms crawling. Try it sometime. (BTW all credit goes to a university public radiostation who supplied the old dish). jerry Radium wrote: Paul Schlyter wrote: In article , Wally wrote: Radium wrote: Hi: If all layers of earths atmosphere had the same thickness of air and the atmosphere somehow grew large enough in diameter to include the sun, would we hear the sounds produced by the sun? If so, what would they sound like? Thanks, Radium Your question deserves a question - what are you looking for? The sound of God? Some sound that has never been heard on Earth before? Some sound humongous? The anger of the Gods? We already have such a natural sound - it's called "thunder"...... The weekday Thursday is the "day of Thor", the "god of thunder".... Whati f the answer was: 'the same sound you hear on Earth listening to the winds etc, which happens to be moving precisely because of Solar activity distributed over the Earth's surface" ??? You tell me! Perhaps he was just curious and wanted to know how we might perceive it? You seem a little provoked by the question itself.... Anyway.... It would most likely be inaudible infra-sound, i.e. sound with frequencies well below 20 Hz. What does distant thunder sound like? Quite low-pitched, like a rumble - right? Wouldn't the extreme heat also produce high-pitched sounds above our hearing range? AFAIK, by the time the sound reaches earth, the frequency and amplitude would probably decrease due to dissapation of energy. And that distant thunder is just only about 10 km away -- the effect would be even more pronounced for a source of sound some 150 million km away!!!! The distance would probably soften the loudness of the sound. However, the sounds generated by the sun would probably be louder [at least at the source] than lightning from the same distance because the sun has so much more power than lightning. Another factor to consider: the sound waves would need some 140 years to propagate from the Sun to the Earth! This is based on the (unrealistic) assumption of a speed-of-sound the same as in out atmosphere. But an atmosphere reaching as far as the Sun would probably consist mostly of hydrogen, and also be much hotter. These two effects would make the sound propagate much faster - but it would still need at least some 10-15 years to propagate from the Sun to the Earth! So if sound waves really could propagate all the way from the Sun to the Earth, the "solar sounds" we would "hear" now (or, more likely, detect with equipment sensitive to infrasound) would have been generated about one sunspot cycle ago! Perhaps the "sounds from the Sun" would be similar to (but maybe weaker than) the changing air pressure when high pressure and low pressure centers pass by us. Since sound is nothing but changes in air pressure, these slow changes in air pressure can be considered a very low-pitched "sound" with a cycle time of several days, i.e. with a frequency of a few micro-Hertz! Would the sounds be similar to the "cosmic noise" we can hear on equipment designed for radio-astronomy? These devices can receiving radio signals produced by the sun and increase the frequency to where it would be audible to the human ear. -- ---------------------------------------------------------------- Paul Schlyter, Grev Turegatan 40, SE-114 38 Stockholm, SWEDEN e-mail: pausch at stockholm dot bostream dot se WWW: http://stjarnhimlen.se/ |

Would the reactions in the sun generate any sound between 20 hz and 20 khz? A source of sound of some wavelength cannot be much larger than the wavelength itself. The wavelength of audible sound varies between some 17 meters and 17 millimeters. The energy producing regious of the Sun is much larger than that. -- ---------------------------------------------------------------- Paul Schlyter, Grev Turegatan 40, SE-114 38 Stockholm, SWEDEN e-mail: pausch at stockholm dot bostream dot se WWW: http://stjarnhimlen.se/ |

So if our ears had an audible range not of 20 Hz to 20 kHz but instead of 0.5 mHz (milli-Hertz) to 0.5 Hz, then that might be what we would hear. -- ---------------------------------------------------------------- Paul Schlyter, Grev Turegatan 40, SE-114 38 Stockholm, SWEDEN e-mail: pausch at stockholm dot bostream dot se WWW: http://stjarnhimlen.se/ |
