Professional rollerblader Julian Bah is no stranger to Atlanta, so it makes perfect sense that he aims to make music that complements his blading prowess. Why not tell us and our B2B sales team about your specific business needs and expectations? Unfortunately for music lovers, many types of ambient sounds can interfere with or even block the sounds coming through their headphones.
Active noise-canceling headphones can do everything that passive ones can do -- their very structure creates a barrier that blocks high-frequency sound waves.
Using these components, noise-canceling headphones are able to provide an additional reduction in noise of 20 decibels. While noise-canceling headphones do a good job distinguishing between the audio a wearer wants to hear and the background noise he or she wants to keep out, some people say that they compromise sound quality by muffling sounds.
For lots more information on noise-canceling headphones and related topics, check out the links on the next page. Audio-Technica announced the introduction of its ATH-ANC1 QuietPoint® active noise-cancelling on-ear headphones, a compact on-ear model that provides outstanding performance, comfort and value. Like all Audio-Technica QuietPoint headphones, including the recently introduced ATH-ANC7b, winner of a CEA Innovations 2010 Design and Engineering Award, the ATH-ANC1 detects environmental noise using miniature built-in microphones, and applies a corresponding sound-cancelling signal.
Unlike some other noise-cancelling headphones, the ATH-ANC1 (and all Audio-Technica noise-cancelling headphones) work even without batteries or when the noise-cancelling feature is turned off.
The Audio-Technica ATH-ANC1 active noise-cancelling on-ear headphones will be available January 2009 online or at Audio-Technica authorized retailers at a suggested retail price of $129.95.
MWC 2013 will sorely miss the launch of the Samsung Galaxy S4 smartphone – now scheduled for March 22 – but to somewhat compensate for this Samsung has announced it will present the Galaxy Xcover 2, which is a rugged smartphone that meets the IP65 military standard. It’s as if smartphones did not come with too many functions but LG is here to just add one more to its upcoming Optimus Vu 2 smartphone – an infrared universal remote control. NEC intros a new professional IPS monitor from its SpectraView family, which feature hardware calibration and is targeted for colour critical applications. At Maplin, we’re always looking for innovations and technology that can help your business work more efficiently.
If you have ever tried to listen to a CD or MP3 player on a plane, then you know the problem well: The roar of the engines makes it difficult to hear what's being piped through the speakers -- even when those speakers are situated in or on your ear. They also add an extra level of noise reduction by actively erasing lower-frequency sound waves.
Notice that the two waves -- the one coming from the noise-canceling headphone and the one associated with the ambient noise -- have the same amplitude and frequency, but their crests and troughs (compressions and rarefactions) are arranged so that the crests (compressions) of one wave line up with the troughs (rarefactions) of the other wave and vice versa.
That means about 70 percent of ambient noise is effectively blocked, making noise-canceling headphones ideal for airline and train travel, open office environments or any other location with a high level of background noise.


Users can also experience a change in air pressure, although ports built into the ear cup are meant to vent air trapped behind the speakers.
The dB scale is logarithmic, meaning that a change of 10 dB represents a tenfold change in loudness. For the best WordPress experience, please update your browser or learn how to browse happy!
The ATH-ANC1 incorporates Audio-Technica’s acclaimed active noise-cancelling (ANC) technology to block out up to 85% of outside noise, while delivering clear and natural sound. Although compact, the headphones deliver powerful, immersive sound, thanks to their precision high-efficiency full-range drivers and premium internal components. In addition to its travel pouch, the ATH-ANC1 comes with a 1.6-foot extension cord, an airline adapter and an AAA battery. It was originally designed for use by pilots, who have a need for great sound quality and efficient reduction of ambient noise to concentrate on their work.It works by using microphones to capture the sound signature of the noise in the area, then using this signature to generate a wave of the same amplitude but antiphase to the original. With a dedicated business team and special services available only to business customers, you can access our electronics and technology solutions through our wide network of over 200 stores, our website with more than 20,000 products or though your personal account manager over the phone. That's because the materials of the headphones themselves block out some sound waves, especially those at higher frequencies.
In essence, the two waves cancel each other out, a phenomenon known as destructive interference. They also help alleviate fatigue when traveling, which can result from exposure to low-frequency noise for an extended period of time.
They change sound waves into electrical signals, while speakers change electrical signals into sound waves. Its active noise-cancelling circuitry is located in an external module attached to its connecting cord, for extremely lightweight on-ear wear. This new wave is played through the headphones into your ears, they cancel each other out - resulting in silence. The best passive noise-canceling headphones, however, are circum-aural types that are specially constructed to maximize noise-filtering properties.
They actually create their own sound waves that mimic the incoming noise in every respect except one: the headphone's sound waves are 180 degrees out of phase with the intruding waves.
You can even use noise-canceling headphones if you don't want to listen to another audio source but do want to cancel out background noise. The ATH-ANC1 features soft, long wearing ear pads for complete comfort, even on long trips or extended listening sessions.
What devices can I connect to these headphones?As they come with a standard 3.5mm jack connection, you can connect these headphones to a variety of everyday devices.


That means they are packed with layers of high-density foam or other sound-absorbing material, which makes them heavier than normal headphones. Also included is an in-flight adapter, so you can use them on short and long-haul flights to remove unwanted engine and cabin noise. The tradeoff of all that extra weight is a reduction in noise of about 15 to 20 decibels (dB).
But considering jet engines create 75 to 80 dB of noise inside the aircraft cabin, passive models have some serious limitations. We've taken our 40 years of bringing real sound to real people and packed it into our exciting new Music for You (M4U) series of high performance headphones.
You're listening to music more than ever before, but now you can do it in comfort and style with PSB's true-to-nature sound quality.

Super soft ear pads and light weight make the headphones "disappear", leaving only rich, detailed sounds. I loved the PSB's overall physicality and their ability to preserve recorded ambience.""I switched back to ANC and prepared myself for an immersive, thrilling listening experience.
