Noise Canceling

Trying to get to sleep when there's unwanted noise in the background can be a fruitless and frustrating experience. You could try and block out the noise with earplugs, but sometimes that's just not enough. The new Hush earplugs are controlled by a smartphone and mask noise with soothing sounds.  Read More

When you dive into the app it becomes pretty clear how much effort Parrot has put into its...

Around two years after the release of its Zik headphones, Parrot is again looking to prick up the ears of audiophiles after a wireless listening solution. The Zik 2.0 headphones are to be released next week, and after a little hands on time with its new set of cans, our early observations are they provide an impressive listening experience.  Read More

HALOsonic constantly adapts to the changes in vibrations coming from the tires against the...

As automakers attempt to make vehicles more energy-efficient, they're increasingly turning to lighter building materials. While doing so may indeed result in lightweight cars, these materials generally lack the sound-damping qualities of their heavier counterparts. That's why Harman and Lotus Engineering have developed the HALOsonic system, which cancels out road noise by making noise of its own.  Read More

The Soundsight wireless headphones with video recording capabilities

Walk through just about any Hi-Fi retailer and before too long you're sure to come across a huge section bursting with personal audio gear. There seem to be headphones and earphones for every taste and budget, including wired and wireless units and models that offer just that little bit extra. So how does a newcomer to the headphones game make a splash in what would appear to be a very well stocked marketplace? Say hello to the Soundsight cans, which are billed as the world's first video recording smart headphones.  Read More

A prototype window design that lets air pass through, but attenuates outside sounds by 30-...

There are few things better than lazing around the house on a warm summer day, whose fragrant zephyrs speak of spicy isles and heaven-breathing groves.* At least, until the neighbors start their leaf-blowers and the city needs to tear up the sidewalks. Noise pollution is one of the scourges of urban and suburban life, which can drown out nature's melodies to cause annoyance, stress, and hearing loss. Now, however, a team of South Korean engineers has invented a remarkable window that lets air in while keeping a great deal of noise out.  Read More

Parrot's Zik wireless headphones feature a touch panel on the right earpiece

Parrot certainly has tried to pack as much technology as possible into its first pair of wireless headphones. Alongside the standard Bluetooth connectivity, the company’s new Zik headphones feature active noise cancellation technology, a touch panel on the right earpiece, a head detection sensor, bone conduction sensor, five microphones and, in a headphone first, integrated near field communication (NFC) technology.  Read More

Canadian high-end loudspeaker manufacturer PSB Speakers has announced its first dip into the headphone market with the release of its Music for You (M4U) 2 Active Noise Canceling, over-the-ear headphones. Built for comfort as well as true-to-nature, hi-fidelity sound quality, the closed back, circumaural cans feature 40mm dynamic drivers, audio-enhancing amplifier technology, and an ergonomic four-point gyroscopic ear pad mount that's said to automatically adjust to the precise contours of the wearer's head.  Read More

The Tohoku University design would change shape during flight to adapt to supersonic speed...

A throwback to early 20th Century aviation may hold the key to eliminating the sonic boom - at least according to researchers at MIT and Stanford University. Strongly reminiscent of biplanes still in use today, the researcher's concept supersonic aircraft introduces a second wing which it is claimed cancels the shockwaves generated by objects near or beyond the sound barrier.  Read More

A Japanese team has invented a portable device that painlessly causes people to stop talki...

For those who don't suffer the talkative gladly, a pair of Japanese researchers may have come up with just the thing - a portable device that can painlessly jam a person's speech from up to 30 meters (98 ft) away. Ingeniously dubbed the "SpeechJammer," you aim it like a gun and, if it's anywhere near as effective as the Delayed Auditory Feedback exhibit I tried at my local science museum, it works like a charm.  Read More

The 2011 Chevy Equinox comes with active noise cancelation technology to combat the noise ...

Charged with the task of getting the fuel economy of the 2011 Chevy Equinox down to 32 mpg on the highway and beat out the 28 mpg-rated Honda CR-V, Toyota RAV4 and Ford Escape, GM engineers employed some rather unconventional fuel efficiency technology – active noise cancellation (ANC). By using the same technique used in noise cancelling headphones, the team was able to let the Equinox’s engine run at a more fuel efficient rpm without the associated low frequency noise and achieve what GM claims is segment-leading fuel economy.  Read More
