Collaborative research led by geologists at Trinity College Dublin has found strong evidence that one of the largest preserved impact structures on Earth was caused by a comet colliding with our planet over 1.8 billion years ago.

By conducting geochemical analyses of the siderophile (iron-loving) elements found in and around the crater fill - and by modelling the impact with computer software - the geologists showed that whatever crashed to Earth was almost completely vaporised on entry.

In a recently published study in the international journal Terra Nova, the Trinity-led geologists explain the rationale behind their assertion that the Sudbury Basin in Ontario, Canada, was caused by a comet - and not a meteorite.

Apart from this other considerations like frequency range, stereo truth sensitivity and other professional parameters should be considered before you purchase the actual selection. With these guidelines, you can be confident of not purchasing a du

The Loudness Wars refers to mixing and mastering techniques that squash music's natural soft-to-loud dynamics. Obviously, you can control the playback volume of your tunes, but once the engineers compress the sound, there's no way to restore the true dynamic range. This problem doesn't just affect obscure records; Grammy Award-winning CDs, like Arcade Fire's "The Suburbs" suffer from loud-all-the-time compression. I love their music, but I find "The Suburbs" hard to listen to. Before we go any further, I'm not referring to MP3 "lossy compression," that's a completely different malady. If you listen to downloaded or streaming music, chances are you're getting the worst sonic effects of dynamic and lossy compression!

Professor of Geology and Mineralogy in the School of Natural Sciences at Trinity, Balz Kamber, said: 'Our findings provide further evidence that some very large terrestrial impact basins were created by comets, which is important and interesting in the context of the early bombardment of our inner Solar System - it might well be that comets were responsible for bringing volatile elements to the young Earth.'

For me, it was the first Led Zeppelin album. The music hit me hard, of course, but it really was the power of the recording; everything else sounded like black-and-white, and Zeppelin's music was in Technicolor. Bonham's drums in particular were so much bigger, more immediate and driving than other records in the late 1960s. Motown and the Beatles records were way up there for me, but Zeppelin's sound was beyond the rest. I wanted to hear that sound more clearly, and that's how I became an audiophile.


In contrast the open-back headphones have perforations over the earpieces which allow the noise and disturbances from the environment to filter in. Because of the noise suppressing qualities, the 'closed-one' designs are definitely recommended over the open one

The Echo Show 5 packs all the usual Alexa-powered voice goodness and adds a 5.5-inch screen, while the Echo Auto is all about delivering Alexa features in your car by connecting to the stereo. While the Echo Auto is an audio-only experience, the ability to access things like navigation and app launchers on your phone is worthwhile. 

n For nobody a pair of headsets assumes the level of importance that it does for a DJ.
Since the common iPods ear buds we own along with our stereophile phones will not cut in a clubbing environment and specialized headphones are required, many brands have launched specialized headphones especially meant for the DJ's. However, it's essential for you to keep some guidelines in mind while purchasing them to lend yourself the best piece to DJ wit

In real life a folk singer isn't as loud as a rock band, but once her recording is compressed she might be as loud as Metallica. Of course, with most types of music the sound isn't turned up to 11 all of the time.

This would give a different outlook to the interior resemblance of the vehicle at the helm. It is strongly adhered to the preamp and amplifier to control it as per the needs and requirements. They are in fact pre-built while purchasing including a complete head unit with utmost connectivity so that you enjoy driving to off-road lanes.

This might be a tough question for a lot of people: defining what good sound is, and separating sound from music isn't easy. It might be impossible to distill it to just one album or song. We tend to like the sound of music we like, and conflate good sound with good music. That's understandable, but when the sound jumps out and draws your attention, take, for example, the sound of Jimi Hendrix's feedback. It was Hendrix's distortion, not his songs, that forever changed the sound of electric guitars.

I recently asked Stereophile magazine's editor, John Atkinson, to name the record that made him take notice of the sound, and without hesitating for a second he said, "Jimi Hendrix, 'Electric Ladyland.'" Good choice!

If you play music in the car through your phone, you should really start thinking about upgrading your vehicle's stereo truth (vivaldiaudio.com) head unit for smartphone integration -- and if you have an iPhone, you want Apple CarPlay. There are perks to using CarPlay beyond access to great music, too: Anyone with an iPhone can use Apple CarPlay for navigation, sending texts, taking calls and more with a simple voice command. You don't need a brand-new ride to experience any of this functionality in a safe, distraction-free way either. Since Apple CarPlay's debut in 2014, aftermarket stereo manufacturers have been designing head units with Apple's automotive OS to fit a variety of vehicle models.
