Noise cancellation technology to transform listening to music

 

ams has recently unveiled new digital noise cancellation technology that will transform the experience of hearing music, having voice calls - and even the world around us - when wearing new, more comfortable true wireless earbuds.

The new audio technology underpins ams’ leading position in the earbud market, which is set to enjoy compound annual growth of 27% in the years to 20231, by which time wireless earbuds are expected to overtake all other wireless and wired product categories to become the most popular type of headphone worldwide.

ams ALC algorithm enables Active Noise Cancellation (ANC) in loose-fit earbud designs Consumer preference today is for loose-fit in-ear wireless earbuds, as they are comfortable when worn for long periods of time. The drawback of the loose-fit earbuds is that more external noise can ‘leak’ into the ear. The new ams digital audio technology platform has enabled the introduction of Automatic Leakage Compensation (ALC) for loose-fit earbuds which adjusts for the air leakage between the earbud and the user’s ear in real time.

This means customers can now also enjoy a great Augmented Hearing and noise cancellation experience while using loose fit earbuds. 

Loose-fit, true-wireless earbuds with ams ALC technology will give wearers a noise-free listening experience similar to that when wearing ANC headphones: ALC-enabled earbuds will produce an almost-silent background to enhance the audio quality of voice calls, music and media content. Their noise attenuation capability of as much as 40dB exceeds that of today’s AS3418 device, which has a noise attenuation rating of 30dB (minimum).

Chris Feige, Executive Vice President for the Ear and Automotive Division at ams, said: “ams’ innovations such as ALC technology are set to usher in a new era of ‘digital augmented hearing’. Building on our new Augmented Hearing Platform, ams is helping customers in the audio industry re-imagine the consumer’s relationship with their listening devices.

"With ALC technology, wearers can have pure silence. The vision for our technology is that earphone and headphone manufacturers will in future let users choose which types and sources of external noise to block out and which to hear.’’

ams Automatic Preset Selection technology to enhance end user experience The Augmented Hearing Engine also provides the platform for the Automatic Preset Selection (APS) feature in ams’s AS3460 Active Noise Cancellation (ANC) product. APS audio technology lets earbud manufacturers develop differentiating features by configuring desired noise cancellation settings optimised for different types of ambient noise. They can develop earbuds which will automatically switch from one mode to another depending on the type of noise it detects, to provide the best noise cancellation performance in all environments.

At a switch-over between preset modes, the AS3460 automatically fades one mode out and the other mode in so that the difference is not noticeable to the user, and so that high noise cancellation performance is maintained con-tinuously. By providing a superior audio experience, the new ams technologies such as ALC and APS help increase the value that consumers attach to the earbuds that they buy either as discrete purchases or as accessories for a mobile phone.
