FCC tells advertisers to CALM down, lowers the volume on commercial breaks
Pretty soon, you won't have to scramble to lower the volume during noisy commercial breaks -- that's if you even watch live TV. After making its way through Capitol Hill, the Commercial Advertisement Loudness Mitigation Act (or CALM) -- which aims to keep the sounds coming out of your flat panel even-keeled -- has just been adopted in a ruling by the FCC. Starting next December, ads and promos will have to remain in-step with the audio levels of scheduled programming. While the affected parties have a full year to get their acts together, the main burden of enforcement lies with broadcasters and MVPDs like Comcast and Verizon FiOS. So, come next holiday season, you'll be able to tune in and tune out without being blown away.
Bionic owners peeved by high-pitched whine, source of the sound still a mystery
Reports have been trickling in for a few days now that Droid Bionic owners were hearing a high-pitched whine when playing media back through headphones. Well, it looks like it's safe to say it's a serious issue. The Motorola support forums are rife with tales of a piercing background tone and loud clicks as the audio hardware fires up and shuts down. In fact, you can find recorded examples of the sounds at the source link. So far it's unclear if the issue is hardware or software related, and Motorola hasn't had much to say about it just yet. We're sure they'll move relatively quickly to address the problem though, before Verizon stores are flooded with returned handsets. [Thanks to everyone who sent this in]
Sony MDR-NC200D noise-cancelling headphones review
Anyone who commutes to a big city knows how loud and distracting things can get -- whether it's the whine of a bus engine, a subway car's ca-clank or just that screaming baby seated behind you. Some folks may find cranking jams through their headphones helpful for blocking out the world, while others would prefer a bit more relative silence. Thankfully, in this modern age there exist headphones with noise-cancelling goodness to help you zone out. Sony hasn't been a stranger to such cans, and recently introduced its $200 MDR-NC200D noise-cancelling headphones; a mid-range option for folks wanting similar benefits of its over-ear NC500D in an on-ear package. The claim is that these pups will reduce "98.2 percent of ambient noise" for up to 22 hours on a single AAA, so we sported the MDRs for the past few weeks as our primary set of headphones to hear for ourselves. You'll find all of the rock blockin' deets just after the break. %Gallery-133277%
Logitech unveils Wireless Headset, Boombox for tablets, smartphones and Radio Raheem
Logitech's family of iDevice-friendly accessories got a little larger today, with the addition of the new Wireless Headset and Wireless Boombox. The former (pictured above) allows users to roam up to 33 feet away from their iPad, iPhone, iPod Touch or Bluetooth devices, features a noise-canceling microphone and offers up to six hours of battery life. The boombox, meanwhile, seems to share much of its DNA with that S715i portable audio dock we got our hands on last year. Aside from its similar design (image after the break), Logitech's Bluetooth-enabled system also features eight custom designed drivers (including, like its cousin, a pair of neodymium 3-inchers), boasts a rechargeable battery with six hours of endurance and can function at up to 33 feet away from any iDevice. The headset will be available sometime this month for $70, with the boombox hitting the market in October for $180 $150. For more details, check out the full PR after the break.
Sony launches party pack of noise-cancelling headphones, your personal discotheque awaits
To the joy and delight of babysitters everywhere, Sony announced a boatload of new noise-cancelling headphones and earbuds to keep you sane in loud situations. Leading the pack are the $200, on-ear active / passive MDR-NC200D headphones, which have a 40mm drivers in each ear, 22-hour battery and folding design. For $150, users wanting portability can cop the smaller in-ear MDR-NC100Ds, which have a lower price tag and 13.5mm drivers. Both headphones feature Sony's "Artificial Intelligence Noise-Cancelling" technology, which claims to automatically reduce ambient noise by around 98.2 percent -- because you know, precision matters. Also launching today are two new smartphone headsets -- the $40 in-ear DR-EX14VP and the $60 DR-XB23VP earbuds -- with connectivity to Android, iPhone and BlackBerry phones, as well as Sony Ericsson, Nokia and other phones thanks to an included compatibility cord. Pulling up the rear are the new iPhone control headsets -- the $60 DR-XB22iP in-ear silicone hybrids, the $40 DR-EX61iP earbuds and the $150 "over-the-head" DR-ZX701iP. Currently accepting pre-orders, the headphones will be available for purchase sometime in October -- just in time to tune out the doorbell this Halloween. Check out the full PR after the break.
Curtain lifts, Audience exposed as iPhone 4's noise cancelling wizard
It's hard not to respect good detective work, so we have to give kudos to the good folks at Chipworks for putting a long-lived iPhone mystery to rest. The iPhone 4 has been applauded for its dual-mic noise cancellation, but nobody knew who actually built the voice processor responsible for this "magic and revolutionary" feature. Jobs and Co. white-labelled a certain chipset inside the iPhone 4 -- it asked the manufacturer to scrub all branding off -- so nobody could properly identify it. Was it made by Apple or a third party? Fast-forward nearly eleven months and it turns out the company responsible is none other than Audience, the same lovely folks behind the Nexus One's renowned noise reduction. We're unsure why this was kept under wraps for so long, but we can understand why Apple would want to remain quiet and keep this superb technology all to itself. A little sleuthing can go a long way, however, so follow the links below to learn how this mystery was unraveled.
Acoustic Poetry concept turns ambient noise into verse
Modern society invests a lot of time and money attempting to drown out our surroundings, but the inability to hear ambient noise can rob one of a sense of place, which can be a very real concern amongst the deaf community. The Acoustic Poetry concept device from British designer Michail Vanis won't miraculously cure the deaf, but it does promise to keep them a bit more in touch. The wooden box is used to capture sound and transmit it to an interpreter, who listens and translates it into text, coming out like something of a free form haiku. It's a communication relay not entirely unlike ones we've seen from a number of other companies, and one that doesn't really necessitate its own stand-alone device. Still, it's nice to see text messaging that can actually keep people more in-touch with their surroundings, for a change -- we still don't recommend using it while driving, however.

Sony's NC-13 buds cancel noise, RF865 cans transmit across a football field
Given the one-size-fits-few nature of most audio products, it's good to have choices, and Sony happens to have two new pairs of headphones designed for very particular segments of your life. If, say, you're a traveling music lover who doesn't happen to have the disposable income to obtain Sony's premium $300 MDR-NC300D noise canceling buds (which the company claims filter out 99 percent of noise), you'll find a cheaper alternative in the new $70 MDR-NC13, which only make a estimated 87.4 percent of background distractions go bye-bye. C'est la vie. If, on the other hand, you need to throw sound from one end of your mansion to the other for hours on end, the MDR-RF865RK wireless headphones might be the wide receiver you've been dreaming of -- Sony claims they'll play audio up to 100 meters away from their dock, which provides up to 25 hours of playtime after a 3.5 hour charge. No price or availability for the wireless cans, which were just announced in the UK, but you'll find the NC-13 on sale at Sony's online store right now. PR after the break.
Pioneer's SE-NC31C-K noise-cancelling earbuds are cheap, but are they effective?
Active noise cancellation's the secret sauce that keeps us counting sheep even when surrounded by the cacophony of crying babies and the dull roar of jet engines -- though we often find the bulky form factor of those serenity-inducing cans unwieldy. Luckily for us, Pioneer has released its SE-NC31C-K noise-cancellation earbuds that promise to remove 90 percent of ambient noise at the flip of a switch on its AAA battery-powered in-line module -- all for around a hundred bucks, which is a far more palatable price than its sound-suppressing brethren from Sennheiser ($320) and Sony ($415). Should you run out of juice, fear not, for you can bypass the noise cancellation features to listen to your tunage as you would with a garden variety set of buds. Given its (relatively) bargain-basement price, we aren't sure how well Pioneer's latest nullifies ambient noise, but there's only one way to find out if they can give the best headset ever made a run for its money. Should you not share our skepticism, hit the source link and grab a pair for yourself.
US Army to deploy Individual Gunshot Detector, essentially a radar for bullets
Latest in our series of "when video games turn real," here's the US Army's newest addition to the wargadget arsenal. The Individual Gunshot Detector, produced by QinetiQ, is an acoustic monitor attuned to tracking down the source of gunshots just by their sound. It has four sensors to pick up the noise of incoming fire, and its analysis of those sound waves produces a readout on a small display that lets the soldier know where the deadly projectiles originated from. The entire system weighs just under two pounds, and while it may not be much help in an actual firefight -- there's no way to distinguish between friendly and hostile fire -- we imagine it'll be a pretty handy tool to have if assaulted by well hidden enemies. 13,000 IGD units are being shipped out to Afghanistan later this month, with a view to deploying 1,500 each month going forward and an ultimate ambition of networking their data so that when one soldier's detector picks up a gunfire source, his nearby colleagues can be informed as well.
Yamaha VSP-1 ambient noise generator shields your voice, water cooler gossips
It isn't hard to picture the scenarios -- banks, hospitals, pharmacies, etc. -- where you need to spill out some private (and probably embarrassing) details in public, but on the other hand, it's no good whispering in a noisy environment. The solution? Yamaha thinks adding more noise is the way forward. Announced earlier this month is the VSP-1 noise generator, which is essentially just a speaker box that masks conversations in your desired direction. With its eight specially tuned ambient noise recordings from the seaside, forest, or river, the VSP-1 managed to mask between 47 percent and 89 percent of the conversations in four Japanese pharmacies, and the customers on the other side of the sound wall even enjoyed the soothing sounds. Alas, Yamaha's little box doesn't come cheap -- you'll have to cough up a hefty ¥105,000 ($1,267) for one when it comes out on April 20th.
Nissan Leaf delayed in UK, backup warning signal to blame
Surprise of all wonders, the Nissan Leaf has suffered another delay, but this time there's at least an amusing anecdote to quote while you wait. You see, The Northern Echo quotes a Nissan spokeswoman as saying that the Leaf's backup warning signal emits a loud beep, but UK law requires that such sounds be disabled between the hours of 11PM and 6AM. "The audible system on the Leaf did not allow for that to be done, so the beeping sound is being removed entirely before the cars can be driven on roads in this country," Nissan said, which will result in a "slight delay" in shipping the cars from the company's Japanese plant. Amusingly, US law actually requires electric cars to make noise these days.
Hyundai Sonata Hybrid was delayed into 2011... by 'virtual engine sound' system
Remember how at the end of last year the US legislature decided to make it mandatory for EVs to churn out an audible noise while in motion? It was all in the name of saving pesky pedestrians from getting in the way of your gliding electro-car, but the new law itself has managed to create a bump in the road for at least one company. Hyundai's Sonata Hybrid was all set to launch in late 2010, equipped with a "virtual engine sound" system that the user could toggle on and off, however the government's request that it be kept permanently on required modifications to the vehicle's wiring harnesses, UI software and user manuals, delaying its debut into late January. These tweaks had to be done "amazingly late in the process," according to Hyundai America CEO John Krafcik, but the delay will at least ensure that all of Hyundai's Sonatas will sound the same. Which is something, we guess.
Ask Engadget: best (non-ugly) noise-cancelling Bluetooth headset for drowning out office noise?
We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Simon, who seems to be not-so-secretly hoping to drown out his entire office. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com. "I need a headset which can block out the background from a busy office. I'm talking repetitive noises such as drilling, background chatter, keyboard clattering, computer fan whirring and the endless static from our building's air conditioner. I would love if this headset had a fair to good quality of sound for MP3s, and it would of course have to have a good microphone for IP phone telephony and Skype. If it didn't look like something from Radio Shack that would be a bonus, and if the microphone was a bit discreet for street and airplane use that would be an added benefit. Lastly the connection to a workstation could be both USB and Bluetooth, with a preference for wireless. Thanks!" Bluetooth headsets have evolved quite a bit since the last time we had this discussion, so we're curious what you're currently using to make work a wee bit more bearable? No need in keeping secrets, right? Speak out in comments below!
Senate approves Pedestrian Safety Enhancement Act, ensures a future for noise pollution
If you've been lucky enough to occupy the driver's seat of a hybrid or electric vehicle you've surely enjoyed the bliss that comes from smoothly and silently pulling away from a stoplight. You've also, surely, run over at least a couple of pedestrians while doing it. (We hit at least eight of the poor souls during our latest Volt test drive.) Sadly, here comes John Kerry and the rest of the US Senate to ruin our Carmageddon-esque fun. The Senate has unanimously approved the Pedestrian Safety Enhancement Act, which requires: ...minimum level of sound emitted from a motor vehicle that is necessary to provide blind and other pedestrians with the information needed to reasonably detect a nearby electric or hybrid vehicle operating at or below the cross-over speed How much sound? Well, they haven't figured that out yet, nor have they figured out up to what speed it must be required, nor what sort of noise is required, but by golly there will be noise. Those answers will in theory be found through the course of a study that will take no more than 48 months to complete, leaving us wonder if current noisemaker options on the Volt, Leaf, and Prius will meet the need. Regardless, if you want a quiet car you'd better start your financing.
CALM Act approved by Congress, should make TV commercials slightly less obnoxious
We did say it'd take an Act of Congress to lower the volume on televisual commercials and, shockingly enough, that's exactly what we've got now. The House of Representatives has given its nod of approval to the Commercial Advertisement Loudness Mitigation (CALM) Act, which, having already cleared the Senate, is now on its way to President Obama's desk for final validation. Once signed into effect, the new legislation will require that all advertisers modulate their volume down so it's no higher than that of the program you're watching, and it'll be the FCC's duty to ensure that they all adhere to the new rule. A year's leniency will be allowed for all those who struggle with figuring out how to turn it down from 11, but after that we should all be able to watch the dying medium that is live television without dreading the commercial breaks.
iPhone Awareness! app selectively filters outside noises into your headphones, saves hipster lives
Apps are funny things. They tend to provide narrow utility -- focusing intensely on one specific thing -- but once you get used to them, you wonder how you lived without them. Take this Awareness! app, for example: it gauges environmental noise levels, sets up a threshold, and then pipes in anything louder than that into your skull alongside your music. Reasons why you'd want that to happen include oncoming SUVs, mothers screaming because their babies are in peril (from oncoming SUVs), or something as benign as your teacher yelling at you for not paying attention in class. There's a nice set of options too, such as manually adjusting how loud a sound must be to be allowed entry into your cranium, as well as pausing of the app or of your music. Awareness! is available for five bucks on the iPhone and iPod touch, and will soon jump on to the iPad, Android, Symbian, and even the Mac and PC.
New Xbox 360 gets a proper teardown analysis: power and noise reductions confirmed
Anyone can take a hammer and rib-spreader to a new piece of hardware. But it takes someone like Anand Shimpi, the man behind Anandtech who has personally suffered through four out-of-warranty Xbox 360 failures, to bring sage analysis to a teardown of the new Xbox 360. His reluctant sixth Xbox 360 is the new slimster (codename Valhalla) which, for the first time, combines the CPU, GPU, and eDRAM onto a single chip -- previous Xbox 360 motherboards featured two discrete packages that split the CPU from the ATI designed Xenos GPU and eDRAM. The design allows for a single heatsink to be cooled by a single, larger fan making the new Xbox "noticeably quieter," measured at 45dB when idle or 51dB with the 1.5Gbps SATA Hitachi HTS545025B9SA00 with 8MB buffer spinning at 5400RPM -- that's down from 50dB and 54dB, respectively, as measured on late 2008 through 2010 Jasper-class 360s. Regarding power consumption, Anand measured a 50% reduction from the original 2005 Xbox 360 (25% less than Jasper-class rigs at idle, or 20% to 17% less under load) and pulled just 0.6W when "totally off" compared to the 2W of vampire power pulled by older 360s. Anand speculates that Microsoft might finally be using cheaper 40nm components. However, we shouldn't expect to see a price cut anytime soon as it will take Microsoft awhile to ramp up the material and manufacturing cost savings. Regardless, with Kinect and several new game titles on the horizon, Anand concludes that there's still plenty of life left in the old Xbox 360 platform for those looking to make the jump.
Ask Engadget: Best noise cancelling Bluetooth headset?
We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget question is coming to us from Jonathon, who's currently preparing for a summer of fun with top dropped. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com. "I'm looking for a Bluetooth headset with the best noise reduction. I've got a convertible and would like to be able to have a conversation with the top down (at least around town, highway would be fantastic but probably unrealistic). So, any thoughts and / or suggestions?" BT headsets have come a long way since we first posted a similar question in 2005, so we suspect the answers here will be quite a bit different. Do you have a particular earpiece that you enjoy while cruising under the open skies? Don't hold back on us, now.
Sony's noise-canceling earphones US-bound in February
You didn't have to wait until now to pick up Sony's MDR-NC300D noise-canceling earphones -- after all, they've been imported from Japan since their June debut. Still, now that the 'buds are hitting official status US routes in February, it'll be a heck of a lot easier to make that impulse buy. No price mentioned, but expect at least a few Benjamins to automatically eject from your wallet.
