"\nImagine that you are waiting for your next flight at the airport, and suddenly, an important business call comes on your phone. Tons of background noise float on the sound scene around you, chatter and conversations of hundreds of people, the never-ending sound of airplanes, and possibly an announcement of the arrival of a flight from Sydney. You must answer this important call and make your voice clear.\n\n\n\nWell, this is a somewhat fictional scenario, especially at the moment and most of the flights have stopped, and work from home, but let's assume that it is real, or you may replace the airport and planes with any place to ride transportation in Cairo, for example, the important thing is that the background noise is really annoying, and it will not allow you Make that important call, or any other call!\n\n\n\n\n\n\n\nNow imagine that when you get that call and talk, that noise will magically disappear, and all that gets to the person on the other end is just your voice, that noise won't pass. Simply put, this is Noise-Canceling Technology.\n\n\n\nFirst, it should be noted that when we talk about noise cancellation, we will mean suppressing the environmental noise next to the caller, which can be transmitted to the caller on the other end. It is different from the term Active Noise Cancellation, which is the suppression of unwanted noise that comes into your ears from the external environment around you, which usually needs a headphone.\n\n\n\nSecond, the word “noise cancellation” itself is a strong word, and the word “suppress” or “blank out” may be more technically correct, but the term “noise cancellation” is more commonly used today, and more widespread.\n\n\n\nWhat is noise canceling technology?\n\n\n\nDo you remember trying cell phone calls 10 years ago, especially when you were talking in a noisy, noisy environment? Certainly, it was a very bad experience, and you will need to shout at the top of your voice in order to hear whoever is speaking on the other end, this still exists of course with some current phones, but most modern phones are equipped with multiple microphones that help in the process of canceling noise in calls.\n\n\n\nModern phones usually have two or more microphones, the first microphone is placed in front of or at the bottom of the phone where the mouth is located, so it picks up the user's voice directly. While the second microphone is placed as far away from the first microphone as possible, and is usually at the top or the back of the phone, where they both pick up ambient sounds. But since the former is closer to the mouth, it picks up more of the sound energy generated by the person's speaking, and the second picks up more noise. And when you subtract these sounds from each other, you get a fairly clean, noise-free sound.\n\n\n\nThis might sound easy, but it isn't. There are several situations in which this technique may fail. For example, imagine that the person is not speaking and all of the microphones pick up the noise, or that the person shakes or turns the phone a lot while speaking, while running, for example. Dealing with these situations is difficult, as engineers have to search for many solutions to support such situations. But despite these difficulties, we can certainly say that the solution to placing more than one microphone works well at the present time, as modern phones suppress noise with great success in most situations.\n\n\n\nFor this solution to work successfully, the distance between the first and second microphones must meet the minimum requirements. For example, in the case of a phone when the user puts it on his ear and mouth to speak, it works fine, unlike, for example, if he talks by opening the speaker.\n\n\n\nHowever, this is just one form factor and it will disappear in the long run. In the world of wearable devices, such as smart watches, and even in today's world of laptops, tablets and smart aids like “Alexa”, there is no form factor here, where users talk. To their devices from different angles and from different distances, and in all of these situations we do not have a workable viable noise cancellation solution.\n\n\n\nAsus AI noise canceling technologies\n\n\n\n\n\n\n\nWith recent advances in artificial intelligence and machine learning techniques, voice technologies have received a huge boost, as different types of those technologies, such as speech recognition, have been able to bypass the point of quality and start usability in real life.\n\n\n\nThe field of noise cancellation is also a promising area within those technologies that rely on artificial intelligence, and Asus recently launched noise cancellation technology in the microphone through artificial intelligence. It suppresses background noise in the microphone for pure audio communication, and comes in its ASUS AI Noise-Canceling Mic Adapter, in the ROG Strix Go gaming headset microphone and in the ROG Theta 7.1 as well.\n\n\n\nThe technology should intelligently eliminate unwanted background noise for clear audio communication during business calls or in games. The new technology uses a processor that works through machine learning to filter and remove other human voices and surrounding sounds such as wind or street noise.\n\n\n\nASUS AI Noise-Canceling Microphone Adapter is the first USB Type-C to 3.5mm headphone jack that comes with a built-in AI noise canceling microphone. The adapter uses AI noise cancellation technology to provide clear audio communication when used with any 3.5mm headphone with microphone. Weighing just 8g, the mini switch includes a digital to analog converter (DAC) and includes exclusive ASUS Hyper-Grounding Technology to prevent electromagnetic interference, giving you noise-free sound.\n\n\n\nIn order to operate it, you only need to connect it to your device, whether it is a PC, laptop or phone, using the USB port, which comes with a small connection that converts from Type C to USB Type A. Then after that, you can connect it to the headphone through the 3.5 connection Mm. Asus recommends using a microphone adapter with headphones that have a built-in microphone.\n\n\n\nWhen connected to a laptop and using a regular speaker, the device works fine, but it is important to note here that the device does not convert simple earphones into headphones with noise canceling technology. There is only environmental noise cancellation for the microphone here, which means it simply suppresses the background noise in your environment so that your voice is transmitted as clearly as possible to the listener.\n"
