Earth's radio signals may be protecting it from space radiation
The Earth's atmosphere bears precious little resemblance to what it looked like at the start of the Industrial Revolution. As radio technology has advanced and spread, the signals that transmitters produce -- specifically the Very Low Frequency (VLF) variety -- have changed the way that the upper atmosphere and the Van Allen Radiation Belts interact, according to a study recently published in the journal Space Science Reviews. In effect, these radio waves may be enveloping the globe like an electromagnetic comforter, protecting it from satellite-frying space radiation.
Creative's new Bluetooth speakers sound vaguely familiar
Creative's family of Bluetooth speakers got a few more additions today. The company unveiled the wireless one-piece D80, which for most intents and purposes, is identical to its colorful sibling the D100, save for a lower price tag at $50 and a loss of battery power. The $300 ZiiSound D5x, meanwhile, looks an awful lot like 2010's D5, though this one plays nice with the newly announced D3x modular speaker and DSx modular subwoofer, both of which are priced at $150 a pop. The D80 is hitting this month and the ZiiSound's various components will be arriving this summer, so don't throw out last year's models just yet. Press info after the break.
Onkyo TX-NR807 and TX-SR707 receivers keep the updates rolling
More than a few people have been interested in Onkyo's x07 receiver updates, and now the newness has come to the TX-SR707 and TX-NR807 models. The outgoing TX-SR706 and TX-SR806 models are well-specced to begin with, and thankfully Onkyo didn't mess with that formula. As you can guess from the "NR" designation, the $1,099 TX-NR807 adds in network streaming (including Pandora, Rhapsody, DLNA and Windows 7) to the 135-Watt/channel output. If you can do without the networking and only need 100-Watts, the TX-SR707 will save you a couple hundred bucks. Both models are THX Select2 badged, Faroudja scaling, and let you pick how to use your rear surround outputs by including both Dolby ProLogic IIz and Audyssey DSX processing. Like we said, Onkyo knows how to fill up the spec list, so head past the break for the full PR details.
Audyssey DSX surround sound takes the speaker-count war to 11
You might think the future of surround audio lies in sophisticated DSP-driven single-box soundbars or even crazy wireless headphones, but Audyssey Labs knows the truth: what you really need is more speakers. Up to 11 of 'em, to be exact, as part of the company's new Dynamic Surround Expansion system. Like the 9.1 channel Dolby Pro Logic IIz, DSX focuses more on the audio in front of you, since that's what your ears are tuned to differentiate the best -- in addition to the left, right, and center channels, DSX includes two speakers mounted up high at a 45-degree angle, and two speakers placed farther out to each side to create width. Add in the two surround back channels from a traditional 7.1 rig and presto -- you're up to 11. Yep, that's a lot of speakers, especially if your loved ones already think a standard 5.1 system is an eyesore. On the other hand -- 11 freaking speakers. DSX-enabled receivers are expected to arrive by summer, just in time to close the shades and spend all day indoors watching movies.[Via Sound and Vision; thanks Will]
