Lang said the audio is one answer to a question scientists are always asking about the universe.
NASA experts more recently converted the sound into a frequency that could be heard by the human ear for release to the general public.īut the audio isn’t exactly the sound a black hole makes - it’s a representation. Here it's amplified, and mixed with other data, to hear a black hole! /RobcZs7F9eĪccording to reporting from the Washington Post, the sound waves were initially discovered in 2003. A galaxy cluster has so much gas that we've picked up actual sound. The misconception that there is no sound in space originates because most space is a ~vacuum, providing no way for sound waves to travel. “It is shifted by millions and millions and millions of factors to completely very low frequencies.” “The sound is not audible to your ears,” he said. He said the actual sound emitted by the black hole is far too low for the human ear to be able to hear. Rafael Lang is a professor of physics and astronomy at Purdue University. The sound, which has been described as eerie and even haunting, is created through a process called “sonification” – in this case turning X-ray satellite data into audio. The mic was released in 2007.A visualization and sonification of the Perseus galaxy posted to twitter by NASA provided by NASAĮarlier this week, NASA scientists tweeted out sound made by the black hole at the center of the Perseus galaxy cluster roughly 240 million lightyears away. The JZ Microphones BH-1 is also known as: Black Hole, BH1. They have a very open, natural quality, which is achieved by a boost in the high mids and the top end, with a dip in the boxy low midrange. I absolutely love the sound of these mics. Clearly you’d need to exercise the same caution when putting this down near tapes and hard drives as you would with a ribbon microphone. There’s no clasp or lock instead it’s held shut with an immensely powerful magnet, and wrenching it open nearly took my fingernails off.
#Blackhole audio review how to#
It all comes in a beautiful wooden box, but you nearly didn’t get this review as it took two of us to work out how to open it. Ditching the 414 in favour of a U87 Ai showed that my memory wasn’t playing tricks on me and they are quite similar sounding, although the U87 seems to have a slightly more elevated HF response than the Black Hole does.Īll the Black Hole mics are packaged identically: with the original BH-1 spring shockmount, in a padded hardwood box that seals shut magnetically. There is a familiarity to the Black Hole’s sound that suddenly strikes me - it sounds far more like a U87 than a 414, with the same softness in the mid range without the loss of clarity. The mic is a perfect option for anyone looking for a versatile high-end mic that will work well in almost any situation. In fact, in cardioid mode, it produced perhaps the best acoustic guitar sound I’ve ever squeezed out of a mic.Īfter using the mic for several weeks, I think the large price tag is easily justifiable. The Black Hole is truly stunning on acoustic instruments. The dual-capsule design allows switching between Cardioid, Omni, and Figure-of-8 pickup patterns, via a switch inside the “hole” in the body. The ends then clamp onto these nubs to secure the clip to the microphone… In practice though, this seems to be a case of form over function, as a 414 XLS in a more traditional suspension mount proved far more effective in suppressing thumps and mechanical vibrations. Two metal nubs inside this cut-out act as the anchor points for an equally unusual-looking clip - best described as a string of rubber beads that you squeeze together, position in the hole and then release. The hole in the microphone body is designed to reduce unwanted reverberation of sound waves off the front of the microphone body. The mic has two circuit boards, one located in each of the narrow outside tubes. The unique body construction is made from powder-coated aluminum. Note that the capsule is edge-terminated unlike the more common center-terminated design, this approach keeps the lead wires out of the mic’s acoustic field. Current production “Golden Drops” capsules use dots of differing sizes. The picture at right shows an early version of JZ’s “Golden Drops” variable sputtering technique, in which drops of the company’s proprietary gold alloy are applied to the film substrate used in the diaphragm. The capsule design, later named GDC2, incorporates twin single-diaphragm capsules mounted back-to-back.
