Although the ability tends to wane as we get older, the human auditory system is pretty good at filtering out background noise and making a single voice able to be understood above the general hubbub of a crowded room. But electronic devices, such as smartphones, aren't quite as gifted, which is why getting Siri or Google Now to understand you in crowded environments can be an exercise in futility. But now researchers have developed a prototype sensor that’s not only able to figure out the direction of a particular sound, but can also extract it from background noise.
The world of products competing for your ears these days is incredibly crowded, from the multitude of budget Bluetooth speakers on up to Sonos and others aiming to drag your dad's treasured hi-fi into the 21st century with top-notch wireless sound. The Nano HiFi NH1 falls somewhere toward the latter end of the spectrum, but maintains a notable level of portability and affordability. Gizmag had the opportunity to play part of our northern summer soundtrack over this nifty setup and we came away with this review.
A new device is aiming to do for audio recording what the GoPro did for video recording. The Instamic is a small, self-contained, high-quality sound recorder. It is aimed at musicians, filmmakers, journalists, bloggers and other people who need a simple and effective means of capturing sound.

Doppler Labs' Here Active Listening system, however, takes things a

it lets users filter out or enhance audio frequencies in real-world
ambient sound before it reaches their ears.
The Sound Torch is a portable Bluetooth speaker that adds a unique visual element to your listening experience thanks to a built-in pyro board, which fires up in different formations based on the music being played.
