What is the Adaptive Active Noise Cancellation function and how does it work?


Bang & Olufsen offers noise cancellation capabilities that focus on sound aesthetics, letting you hear every detail in noisy environments without compromising on the quality of the sound. Our advanced noise cancellation technology is expertly tuned by Bang & Olufsen sound engineers in close collaboration with our partners to reproduce the original sound material as authentically as possible, effectively blocking out ambient noise without adding unwanted effects to your music.

Beoplay HX feature a new generation of digital Adaptive Active Noise Cancellation (ANC) technology. The noise cancellation is processed through a hybrid ANC system which is a combination of a feed-forward ANC and a feedback ANC. The outside microphone employs the feed-forward technology, which measures incoming, ambient noise and suppresses the mid to upper frequencies – an example being the main part of human voices. The inside microphones utilise feedback technology. It senses the music from the speaker as well as the lower to mid frequencies of the ambient noise. It then separates the two and generates an anti-noise signal that blocks out humming noise from e.g. aeroplanes, trains and buses. When the adaptive feature is activated in the Bang & Olufsen app, the headphones will analyze the surrounding sounds and automatically select the most suitable noise cancellation algorithm. If the background noise changes, the ANC will adapt.

Thanks to the memory foam and the genuine soft leather of the ear pads, Beoplay HX seal out unwanted noise, blocking out high frequency sounds through passive noise cancellation. Combined with the Adaptive Active Noise Cancellation technology, Beoplay HX allow you to immerse yourself completely in the listening experience, and these features also make it possible to enjoy music without raising the volume excessively.
