On September 25, Huawei officially launched its flagship TWS headset FreeBuds Pro 3 at the high-profile autumn full-scenario new product launch conference. This headset uses the new StarLight connection core technology (Polar code technology) and Kirin A2 chip, becoming the industry's first "StarLight headset", bringing super CD-level lossless sound quality and excellent noise reduction effect, which is unprecedented
After the National Day holiday, a "hardcore video" of using Huawei FreeBuds Pro 3 to test call noise reduction at a rocket launch base attracted the attention of many netizens.
In order to more intuitively demonstrate the call noise reduction capabilities of FreeBuds Pro 3, the tester chose the rocket launch scene. The media in the video put on Huawei FreeBuds Pro 3 and went to the rocket launch base to test the call noise reduction function while watching the rocket launch
In the video, the rocket was launched into the sky with a loud sound. . Despite the roar of the rocket, FreeBuds Pro 3 is still able to capture the user's voice and transmit it to the other end. This powerful performance amazed the media teachers present
Nowadays, noise reduction has become the standard feature of TWS headset products, but active noise reduction capability alone is far from enough. Call noise reduction is the touchstone of TWS noise reduction capability. The reason why this is so That’s because call noise reduction has always been a difficult problem for the industry to solve.
Noise is everywhere in our lives. For example, there will be roaring sounds when high-speed trains and subways are running, noisy people in amusement parks, shopping malls, and tourist attractions, wind noise during outdoor sports, and ubiquitous signal interference, etc. Therefore, calls have become a common scenario for users wearing TWS headsets. However, in the past, the noise reduction capabilities of some TWS headsets were limited to "isolating external sounds." Once the call function is turned on, the powerful active noise reduction capabilities will "invalidate." In the above-mentioned noisy environment, the noise often overwhelms the other party's voice, and users cannot communicate normally.
is different from "active reduction" Behind the "call noise reduction" is the test of human voice processing, computing power, and comprehensive capabilities of TWS headphones. Only with the support of powerful algorithms and chip computing power can the human voice be accurately "reduced" in noisy environmental sounds. "Refined" to isolate useless environmental noise, allowing users to have a smooth conversation with the other party on the phone in any environment.
Huawei FreeBuds Pro 3 is newly equipped with Silent Call 2.0, which improves the noise immunity of calls by 5 decibels and improves wind resistance by 80%, thus bringing a purer silent call experience. Therefore, facing rocket launch, Huawei FreeBuds Pro 3 can be so calm and relaxed. With Silent Call 2.0, Huawei FreeBuds Pro 3 demonstrates the true definition of "the most powerful call noise-cancelling TWS headset"
So how does Huawei FreeBuds Pro 3 achieve such powerful call noise reduction capabilities? What other big moves support the implementation of Silent Call 2.0?
Huawei’s Kirin A2 chip makes it possible to extract pure human voices in noisy environments. This powerful chip is integrated into the small headphone handle
The Kirin A2 chip integrates an advanced Bluetooth processing unit and powerful dual DSP based on the compact size of 7.27*5.2*1.29mm. Audio processing unit, ultra-low-power application processor and independent power management unit
Kirin A2’s high-performance audio processing unit has up to 2 *300M powerful computing power, the computing power performance is 2 times higher than that of the Kirin A1 chip, making real-time processing of high-fidelity audio possible, and the active noise reduction capability is increased by 50%.
Kirin A2 has more powerful audio computing capabilities, can process larger amounts of data, and uses more complex multi-channel neural network algorithms to process vocal frequency bands and full-band audio signals separately, and then dynamically fuse them , so that users can get an excellent call noise reduction experience in any environment
The "Silent Call 2.0" feature of Huawei FreeBuds Pro 3 is powered by the Kirin A2 chip. To achieve industry-leading call noise reduction effects, in addition to the co-design of hardware architecture, algorithms and anti-wind noise technology, the cooperation of software and hardware is also required
Specifically, in terms of hardware architecture, Huawei FreeBuds Pro 3 Using a high-sensitivity bone conduction pickup microphone, the pickup capability is 2.5 times higher than the previous generation; in terms of software algorithm, Huawei FreeBuds Pro 3 is equipped with Huawei’s self-developed multi-channel deep neural network call noise reduction algorithm, which performs neural network training through frequency bands and combines AI Dynamic fusion technology retains more vocal details; in terms of anti-wind noise design, Huawei FreeBuds Pro 3 adopts a backward-facing wind-proof structure microphone for calls, intelligent anti-wind noise algorithms, and big data learning and modeling for wind noise scenes. , the final call resistance to wind noise is increased by 80%, and even in strong winds of 9m/s, users can still have trouble-free calls.
In the end, through the collaborative efforts of software and hardware, even in noisy and complex scenes such as high-speed trains, subways, airports, or at the beach, riding bicycles, etc. In a scene with strong wind noise such as walking, wearing Huawei FreeBuds Pro 3 for voice calls not only allows you to hear the other party’s voice clearly, but also allows the other party to hear your own voice clearly
Also based on the powerful computing power of Kirin A2, Huawei FreeBuds Pro 3 is no longer limited to a fixed noise reduction mode, but brings The combination of three modes of noise reduction and real-time noise reduction creates a "sound-customized" noise reduction experience for users - Smart Dynamic Noise Reduction 3.0.
Huawei FreeBuds Pro 3 uses real-time adaptive noise reduction function and uses full-time and full-frequency accurate calculation to customize exclusive noise reduction parameters for users according to different noise environments and wearing conditions. Compared with the previous generation, the average noise reduction of Huawei FreeBuds Pro 3 in the main living environment noise frequency band (50Hz-3kHz) has increased by 50%
The noise reduction function of Huawei FreeBuds Pro 3 has been upgraded to Smart Dynamic Noise Cancellation 3.0, which allows every user to enjoy the noise reduction effect like tailor-made exclusive clothing, achieving a true thousand-person, thousand-ear experience.
In addition to "customized" noise reduction, Huawei FreeBuds Pro 3 also supports full-link lossless sound quality - its built-in Kirin A2 chip is the first audio chip equipped with Polar code. It brings 6dB anti-interference capability, which doubles the anti-interference capability of audio Bluetooth transmission, doubles the transmission distance, and saves power consumption by 40%. Relying on Polar code technology, the audio transmission bit rate of FreeBuds Pro 3 stably runs at 1.5Mbps, achieving true full-link super CD-level lossless sound quality.
Huawei FreeBuds Pro 3 has also been upgraded to spatial audio 2.0, using its own high-resolution spatial model algorithm. This upgrade reduces latency by 25%, improves dynamic response flatness by 25%, and improves resolution accuracy by 40°. In this way, the user's spatial perception has been comprehensively upgraded
Finally, there is also a new smart experience brought by HarmonyOS 4, including offline search function, ring search, smart missing reminder and other functions, as well as audio services A series of powerful functions such as cards, full-scenario super terminal, audio connection center, audio sharing, and smart broadcasting.
The above is the detailed content of Huawei FreeBuds Pro 3: Challenge rocket launch noise and become the 'invincible king' of call noise reduction TWS. For more information, please follow other related articles on the PHP Chinese website!
