In a recent interview given to Engadgettwo key figures at Apple, Kate Bergeron (vice president of hardware engineering) and Eric Treski (marketing director for AirPods), have revealed interesting details about the technology behind the AirPods 4.
Even though these are earphones with an “open-ear” design, therefore without the classic silicone inserts, Apple has managed to integrate a Active Noise Cancellation (ANC) high-level, making these new devices even more interesting.
One of the main innovations of the AirPods 4 resides in the chip H2which represents the beating heart of the ANC system. Thanks to thecomputational audio advanced, Apple has made a step forward in noise reduction without having to resort to traditional ear tips.
Second Bergeronnoise processing on AirPods 4 is even more complex than on AirPods Pro, due to the challenge of achieving a similar result in an open design. Wooden skis He added that the H2 chip not only manages the quality of the ANC, but also continuously listens to the surrounding environment through the microphones, to attenuate external noise as efficiently as possible.
Apple has changed the shape and theacoustic architecture of AirPods 4 to achieve better noise isolation. This, combined with the optimization offered by the H2 chip, allows for truly amazing active noise cancellation, especially considering that it does not use silicone tips that normally help seal the ear and improve the effectiveness of the ANC.
The AirPods 4 are now available on the market, but only the high-end version includes active noise cancellation. This differentiation allows users to choose the variant that best suits their needs, while maintaining access to advanced features such as ANC in a competitive price range.
