This is how Apple has achieved great noise cancellation in the AirPods 4 without using pads

The secret that led Apple to launch the AirPods 4 with active noise cancellation without pads has been revealed, the idea arose from none other than the pandemic

AirPods 4 with active noise cancellation are a marvel of today’s technology

Talking about the origins and foundations that laid what Apple is todaysuch as establishing what Jobs would have in terms of his fortune if he were still alive, the tenth anniversary of the Apple Watch and the secret about its design, It’s time to talk about a great feat. We are referring to the AirPods 4 and the How did they manage to give you active noise cancellation without taking into account that they don’t have pads?The story goes back to the pandemic, a group of the AirPods team proposed it while everything started as a dilemma.

During the pandemic, the AirPods team set out to bring active noise cancellation to regular AirPods

According Engadgetthey obtained Kate Bergeron’s statements What is the Vice President of Hardware Engineering at Apple. They touched a bit on the topic of how the iPod and the headphones that came with it were enough to make a product like AirPods available today. Then, The EarPods seemed like the perfect headphone design but we weren’t ready to see the best version of him yet. AirPods are partly based on those headphones that were shipped with the iPod. but today they have the most technology possible in a pair of such small devices.

The initial challenge was to “learn a little about human physiology” and precisely understand how fit the best shape to the users’ earsThey had no idea how much information they would need to accomplish that challenge. As time went by, Thanks to the EarPods, they were able to collect data more quickly and that is also a fundamental part of continuing the development of future generations of AirPods.

It wasn’t until the pandemic that the group behind AirPods came up with the idea of ​​taking the simplest AirPods to the next level of greatness.The AirPods Pro and AirPods Max already had active noise cancellation but the case was complex because they wanted to preserve the design and essence of the AirPods. Until 2021, after endless tests and a lot of information, the day that everyone wanted was reached.. Kate Begeron and Eric Treski, director of marketing for AirPods, They witnessed the first demonstration that the open dilemma in a pandemic could be a reality.

AirPods 4 are ideal for users who hate ear cushions

We were stunned. We have something really good here, we need to go after this and make it happen.

Active noise cancellation in a comfortable design and fit on AirPods 4

They carried out acoustic and computational work for a long time. in addition to the repetitive testing process regarding the design of the AirPod to make them as comfortable as possible. The secret to the fit of the AirPods 4 basically comes down to the tip of the earbuds which is what helps to provide better comfort.

The H2 chip and built-in microphones themselves allow Apple to monitor this setting. and can offer the best real-time active noise cancellation algorithm. That’s why these headphones don’t have ear pads, technology at its finest has eliminated a physical form factor.

Another point to take into account about active noise cancellation lies directly in what Apple calls “acoustic architecture”. Eric Treski indicates that Adaptive EQ contributes to an ideal and constant adjustment of equalizers which in turn benefit in having better active noise cancellation and audio quality. The H2 chip is supporting this incredible functionality all the time.

If it was thought that the absence of pads was better for transparency mode, we are wrong. Treski indicates that it is much more complicated for themeven more so than active noise cancellation. Finally, they noted that the design refresh on the AirPods 4 also contributed to offering a slimmer case. It’s like “a magical experience” according to Kate Bergeron. Interestingly, The physical button was removed from the case which allowed to eliminate much of the thickness that characterized it and now it’s a capacitive button. The same thing also contributed to the case having an IP54 certification like the AirPods.

There is no doubt that We are facing one of the best generations of AirPods in historyAudiophiles and music lovers, as well as other audio content lovers, will be able to witness what has been revealed in this interview. If a large part of this work is used in the future, Apple could set new milestones with the upcoming AirPods Pro 3.
