AB1595 - The Flagship AI Audio Platform

Significant Enhancement in "Speech Noise Reduction" Performance with Up to 10 Microphones: the flagship AB1595 chip from Airoha Technology brings the stringent speech quality standards of professional-grade boom microphones with Microsoft Teams Open Office certification to consumer-grade boomless, omnidirectional headsets. By collaborating with up to 10 microphones for ambient sound capture and using AI algorithms to accurately identify and distinguish user voice and environmental sounds, it achieves professional-grade speech quality. Compared to consumer-grade headsets, the AB1595 can enhance "voice noise suppression" from 10 dB to as low as 40 dB, especially in noisy environments like offices and cafes, significantly optimizing speech quality and bringing professional-grade teleconference functionality to consumer headsets.

  • The AB1595 chips feature real-time adaptive ANC significantly enhancing the depth and bandwidth of environmental noise attenuation. They can further detect the user's wearing condition (i.e., good fit or loose with leakage), performing adaptive compensation. The internal filter settings automatically adjust based on the user's wearing conditions and different environmental noise types, balancing the best noise cancelling effect with the comfort of reduced ear pressure, providing the most comfortable wearing, and listening experience.

  • Even in noisy environments, users can clearly hear the speech from the audience they are speaking to while wearing the headset, such as on airplanes, in stadiums, or on subways.
