Qualcomm presents itself at IFA 2020 introducing a new active noise reduction technology, designed specifically for the true wireless earphone market. It is called Adaptive ANC and can be used as a reference solution by OEMs who want to make use of the technology accompanied by specific APIs for tailor-made design, thus accelerating the development of a product.
What are the benefits of Adaptive ANC? Qualcomm's idea is to guarantee better comfort and constant sound quality, the company claims that the comfort factor is decisive for the purchase of a pair of earphones. The numbers testify to this, Qualcomm has in fact designed Adaptive ANC listening to the opinion of consumers: in a survey 53% of them indicated comfort as a key parameter for the purchase of a pair of earphones.
The performance of an ANC system normally depends on characteristics such as the form factor of the headset, the width of the auricle and its hermetic seal, resulting not always the same and pleasant for everyone. Adaptive ANC will offer an automatic adaptation system in relation to the user's activities, reinforcing or not the active cancellation depending on what we are doing at that moment and where we are. For example, let's think about how Qualcomm's ANC system will dynamically adapt to use during running sessions or even more immediately during a simple movement of the head.
Apparently no particular calibrations will be needed, Adaptive ANC will work transversely in all modes, both in call and listening or while using a voice assistant, adapting to environmental conditions and thus offering a more linear listening experience. All of this will result in a detailed reduction of external noise, which could be mitigated in quiet environments or increased in noisy places. Qualcomm hasn't revealed further details, but does let it be known that Adaptive ANC is now available on the latest premium-level Bluetooth audio SoC, the QCC514x, unveiled in March.
