Conexant Brings Active Noise Cancellation and Ambient Inclusion to USB-C Headsets

At Mobile World Congress Shanghai (29 Jun. - July 1, 2016), Conexant Systems introduced their new CX20888, an Audio Stereo CODEC that is the first single-chip solution to allow USB-C-compliant active noise cancellation (ANC) and ambient noise inclusion in headsets. This new USB-C solution features an integrated ARM Cortex M0+ MCU and Class-H headphone amplifier, enabling new class of features for smartphone, PC and gaming headsets. Its active noise cancellation eliminates up to 30dB of external sound, for a clearer, more enjoyable listening experience.

Hush, successfully funded on Kickstarter, is the world’s first set of connected earplugs that wirelessly connects to a smartphone, to help people live and sleep when it’s noisy. Hush combines noise-masking earplugs with an app to isolate users from distractions that may be keeping them from sleeping, while still letting key notifications in.

Public address systems in public spaces have to clearly inform persons in danger about escape information and directions in case of an emergency. NTi Audio’s XL2 Acoustic Analyzer reliably measures the Speech Transmission Index (STI) and the results can be imported into the STI Reporting Tool which now also assigns the same ambient noise spectrum to multiple speech intelligibility measurement results.

NTi Audio’s XL2-TA Sound Level Meter is the first type approved sound level meter with a certified input keypad for legal noise nuisance assessment. The combination of an XL2-TA Sound Level Meter for Noise Monitoring in combination with the external Input Keypad meets the requirements of the standard IEC 61672 with immediate marking of noise events and annoyance complaints.
