Qualcommin kehittämä mukautuva ja aktiivinen vastamelutekniikka kasvattaa langattomien nappikuulokkeiden käyttömukavuutta ja äänenlaatua

Berliini, 3. syyskuuta 2020 – Qualcomm Technologies on julkaissut tänään uuden Qualcomm Adaptive Active Noise Cancellation (ANC) -teknologian, joka parantaa vastameluominaisuuksilla varustettujen nappikuulokkeiden käyttökokemusta. Qualcommin mukautuva vastamelutoiminto (ANC) on suunniteltu parantamaan käyttömukavuutta sekä tarjoamaan tasaisen laadukasta ääntä langattomiin kuulokkeisiin mukauttaen äänentoiston korvanappien fyysisen sopivuuden mukaan – myös reaaliajassa käytön aikana, jolloin nappien istuvuus voi vaihdella käyttäjän liikkeiden myötä.

”Meidän 2020 State of Play -raportti osoittaa, että kuluttajien vaatimus aktiiviselle vastamelutekniikalle on kasvanut vuosi vuodelta, ja on nykyään neljänneksi halutuin ominaisuus nappikuulokkeissa. OEM-valmistajille voi olla haastavaa tarjota laadukas vastamelusuorituskyky, koska nappikuulokkeet eivät aina istu yhtä hyvin. Myös laitteiden käyttötapa- ja paikka vaihtelee suuresti. Suunnittelimme mukautuvan ANC:n, jotta asiakkaamme voivat tarjota tasaista äänenlaatua mahdollisimman suurelle kuluttajajoukolle”, sanoo Qualcommin Voice, Music & Wearables -yksikön johtaja James Chapman.

Qualcommin 2020 State of Play -raportti paljasti, että langattomien nappikuulokkeiden käyttömukavuus on keskeinen ostokriteeri peräti 53 prosentille kuluttajista. Vastamelutoiminnon suorituskyky on usein riippuvainen siitä, miten syvälle korvaan nappikuuloke työnnetään, ja useiden käyttäjien mielestä tiukasti korvassa istuva nappi on epämukava. Mukautuva ANC vähentää ominaisuuden riippuvuutta nappikuulokkeiden istuvuudesta, jolloin nappien ei tarvitse olla niin tiukasti korvassa. Nappien istuvuus vaihtelee useissa käyttötilanteissa, kuten juostessa tai päätä kääntäessä. Mukautuva ANC muokkaa ääntä reaaliajassa nappien istuvuuden sekä läpivuodon määrän mukaan, riippumatta käyttäjän aktiivisuudesta tai kuulokkeiden käyttöympäristöstä.

Qualcomm’s Breakthrough Adaptive Active Noise Canceling Technology is Designed to Deliver Increased Comfort, Consistent Performance and Improved Sound Quality for True Wireless Earbuds

3. syyskuuta 2020 – Qualcomm Technologies International, Ltd., a subsidiary of Qualcomm Incorporated, today launched Qualcomm® Adaptive Active Noise Cancellation (ANC) a new technology designed to deliver an improved user experience for earbuds with integrated ANC. The Adaptive ANC is designed to enhance user comfort and provide consistent sound quality for true wireless earbuds by adapting its performance to meet variations in how an earbud fits in a user’s ear, and adapt in real-time to changes in fit as the earbuds are in use.

“Our 2020 State of Play report found that consumer demand for active noise cancellation has increased year on year and it is now the fourth most wanted feature for earbuds. This makes it a key differentiator for manufacturers,” said James Chapman, vice president and general manager, Voice, Music & Wearables, Qualcomm Technologies, International, Ltd. “However, it can sometimes be difficult for OEMs to deliver consistent ANC performance because earbuds will not always have the same fit or be placed in the ear in the same way, and both how and where a consumer uses these devices can vary greatly. We have designed our Adaptive ANC to help customers deliver consistent performance levels and great sound for the largest possible number of consumers.”

Enhanced Comfort and Consistent Sound Quality

Our 2020 State of Play report also showed that in-ear comfort for true wireless earbuds is a key purchase criterion for 53% of consumers surveyed. Effective ANC performance is usually dependent on creating a tight seal once the earbud is placed into the ear which can cause discomfort and be difficult to achieve. The Adaptive ANC is designed to reduce the dependency on forming a tight seal so a user doesn’t need to push or twist the earbud into the ear. Variation in fit can also occur depending on user activity, for example as a user is running, walking, or even moving their head. Adaptive ANC is designed to dynamically adapt performance in real-time according to the tightness of fit and the level of leak-through no matter how or where the earbuds are being used.

Designed for a Seamless User Experience

The Adaptive ANC is designed to help make the user experience as seamless as possible from the moment a user takes the earbuds out of the box, with no need to conduct a fit test, self-calibration or to try out multiple sets of eartips. The technology is also designed to operate across virtually all modes and works concurrently as a user transitions from one mode to another. For example, the technology is designed to allow a user to switch from taking a call, to listening to music, to using a digital assistant to asking a question – all with no interruption to the ANC. Adaptive ANC is also designed to support automatic adjustment to environmental conditions, by ramping down the ANC strength for quiet spaces or conversely ramping up for noisier environments.

Developer Choice and Flexibility

Adaptive ANC can be used as Qualcomm Reference Design solution to help those OEMs who want to develop their product faster, and for those customers who want to add further differentiation an API is provided to customize the solution to provide a very unique Adaptive ANC experience. The technology also provides developers with freedom of choice of form factor, from fully occluded, semi-occluded and non-occluded earbuds.

Adaptive ANC is now available on our latest premium tier Bluetooth Audio SoC – QCC514x. Designed to meet the demands of a truly wireless sound experience, the QCC514x integrates support for Voice Assistants, premium wireless audio quality, and extended battery life, among other features, and now Adaptive ANC that further improves the overall true wireless sound experience.
