NXP Semiconductors N.V.has announced a new echo cancellation noise reduction solution (ECNR) that significantly reduces the problem of noisy voice communications and provides carmakers with a consumer pleasing, hands-free calling experience. The cost-effective solution combines innovative ECNR software that can be easily ported onto NXP i.MX processors and NXP’s leading car radio tuners and DSPs. The new NXP ECNR solution is also ITU-T P1110 and CarPlay® pre-certified.

Echo and noise can make communication on the road difficult. Echo occurs when the speakers within a car transmit a voice signal from an incoming call, which subsequently ricochets through the vehicle and returns to the microphone. This causes the caller to hear their own voice, which is distracting and can result in broken communications. Additionally, road noise from fans, exhaust, tires, windows and passengers can infiltrate calls and render them unintelligible, ultimately disrupting the driving experience and causing frustration.
