The freedom that comes with small form factor, ultra-lightweight wireless
hearables is fantastic. However, despite improvements in environmental
microphone noise reduction how often have you said or heard,
“I’ll have to call you back when there’s less
noise.” Or how about, “It’s too windy, I can’t
hear you” or “I have no idea what you said, just text me
instead.” Sound familiar? Well these statements are among the most
common interruptions to phone calls made while wearing wireless earbuds.
Picking up on the Power of the Spoken Word
Imagine earbuds that can truly eliminate wind noise on a stormy day. Tune out
background chatter in bars and restaurants. Effectively create a zone of
tranquility around you at loud parties and sports events, so you can easily be
heard with perfect clarity.
While other environmental noise-reduction technologies have improved over the
last few years, NXP’s ultra-low-power
MiGLO
technology really does solve the noise-isolating challenge. It does this by
combining a compact near field magnetic induction (NFMI) single-chip audio solution with two mics in each earbud and our Smart Ear software.
At the heart of any noise-isolating challenge is the ability to accurately
tune into only what is being said or heard. This is where 2+2 beamforming
comes into play. The two microphones located in each earbud allow NXP’s
Smart Ear software to precisely center in on the voice of the wearer while
simultaneously picking up surrounding extraneous noise and filtering it out.
NFMI Brings Robustness and Efficiency
MiGLO is based on NFMI technology. With a proven track record in hearables,
NFMI supports high-quality audio and data streaming across small distances
(less than 1m) while boasting ultra-low power consumption. It delivers a
stable connection between the left and right earbud, while also increasing
privacy and reducing issues with interference compared to other wireless
technologies.
NFMI technology first came into use in the world of hearing aids, enabling
users to focus in on the speech of the person in front of them, rather than
amplifying the sounds of an entire room. It has since been developed to
maximize the reliability and ease-of-use for voice-related applications such
as voice assistance, translation and calling. And thanks to our tightly
controlled left/right audio synchronization ensures an outstanding stereo
image for your music.
Setting the Noise-reduction Standard
Already in use by a number of earbud and hearable manufacturers, the days of
complaining about poor call quality and clogged audio are over. MiGLO brings
hands-free, noiseless calls, true wireless stability and crystal-clear voice
amplification. So you will never again hear or say, “I’ll have
to call you back when there’s less noise.”
