Sony introduced the world ’s first earphone with “ digital engineering for precise noise canceling”- although we ’re not sure precisely what that means - these headphone have three different environmental modes , and a switch to let the outside noise in . Sony claims to block 99 percentage of noise in the 160HZ reach ( which is the same as a jet engine ) . The MDR - NC500D will be usable in February for $ 400 . Update : Since several company deal digital noise scratch headphone , I asked Sony what exactly made these a mankind ’s first .
They admitted that they were n’t certain why there are other headphones advertised as digital noise set off , since they all use an analog mechanism for match out the sound . These do an analog to digital conversion using a digital signal processor with three filter . That should , in possibility , leave in far better sound since the sound gets houseclean up with digital EQ before you get word it .
SONY PRESENTS WORLD ’S FIRST DIGITAL NOISE CANCELING HEADPHONES
Digital Signal Processor supercharge Noise Canceling Accuracy
LAS VEGAS ( CES Booth # 14200 ) , Jan. 6 , 2008 – For anyone who drop more time reclined on an airplane rather than sitting at home in a reclining chair , Sony today unveil the world ’s first digital noise canceling headphones .
The lightweight , MDR - NC500D modelling headphones use digital engineering to more accurately bring down focus - inducing noise from planes , trains and motorbus , while providing a high - quality audio experience .
The headphones can reduce up to 99 percent of ambient noise at 160HZ , which is the peak frequency of a blue jet engine .
“ By going digital , our noise canceling headphones drive home a balanced and rich speech sound , while delivering the highest spirit level of interference cancellation when jaunt or commutation , ” say Andy Bubala , managing director of selling for personal audio accessories at Sony Electronics . “ The power to fetch digital technology to ultra - light earpiece should keep Sony as the industry leader in the earpiece market place . ”
Digital Defeats Analog
The increased rate and accuracy of noise reduction in these six - ounce headphones is due to the usance or a unequalled digital interference canceling software locomotive , a set of digital filters locate in the built - in digital signal mainframe .
To start the disturbance canceling process a mike bump inside the auricle cupful of the earpiece takes an analog audio reading and convert the phone to digital . At the same sentence , the analog audio input signal is converted to a digital sign and sent through a digital equalizer to enhance the mid - range vocals and alleviate the excess bass — two characteristic that can be negatively affect in most noise - scratch earpiece .
The audio signaling is compare to the noise signaling , and the DNC software engine uses a digital filter to slay ambient noise that registers in the desire frequency range . The resulting signal is converted back to analog and get off to the headphone ’ equipment driver for sound replication . Bubala said this digital - based process enable more effective haphazardness cancellation than is possible using analog filter technology .
Sony ’s DNC software system railway locomotive makes it possible for these digital noise canceling earphone to offer three distinguishable interference canceling modes optimized for dissimilar surroundings : plane , train/ bus , or office .
By press an unreal intelligence racket canceling button found on the outside of the veracious capitulum spell , the headphones glance over the ambient noise visibility and intelligently select the good mode to invalidate out the highest amount of undesirable sound .
Each fashion uses a different digital filter in the digital sign mainframe , which has been specifically tuned for effective racket reduction in these different good environments .
Quality , Comfort and Style
Sony grow the MDR - NC500D digital racket cancel headphones with recollective flights and stress relief in mind . They are powered by an national lithium - ion assault and battery that can lock for up to 16 hours on a single charge . They also have an external battery boxful that hold two AA battery for when there is no approach to a rampart nag .
To put up solace during long time of day of habiliment , the new phone feature thick , urethane froth cushioning in the ear piece that foreshorten pressure and pinching on the outer capitulum . To add style to comfort , the auricle cup are finished with black lacquer and have a single - sided cord connection for convenience .
The headphones ’ monitor electrical switch permit you to temporarily set aside the haphazardness cancellation feature of speech and muffle the medicine to listen to flight of steps announcements .
The MDR - NC500D earpiece will be available in February for about $ 400 at sonystyle.com , at Sony Style ® retail stores ( www.sonystyle.com/retail ) , at military base exchanges , and authorise dealer nationwide .
