نقاط ضعف: قابلیت Active EQ ممکن است باب میل همه نباشد - طراحی خسته کننده و قدیمی
یکی دیگر از بهترین هدفون های حذف نویز، هدفون بوز QuietComfort 35 II است. هدفونی که تقریبا از همه جهات به جز چندین بروزرسانی جزئی برای سال 2018، شبیه به هدفون محبوب و مطرح QuietComfort 35 است. یکی از مواردی که به این نسخه جدید اضافه شده، دستیار صوتی گوگل است. به این ترتیب با خرید هدفون نویز کنسلینگ کامفورت 35 ‌II می‌توانید از ویژگی حذف صدای مزاحم بوز که یکی از نقاط قوت هدفون‌های این کمپانی است، در کنار صدای با کیفیت به علاوه یک دستیار صوتی برای پاسخ دادن به هر سوالی که هنگام استفاده دارید لذت ببرید.
هدفون QC35 II یک هدفون بسیار عالی برای کسانی است که دائم در حال سفر یا رفت و آمد هستند. بوز در این محصول خود توانسته تعادل خوبی میان ویژگی‌های مختلف ایجاد کند. موضوعی که می‌تواند نظر مثبت بسیاری از کاربران را به خود جلب کند. با وجود اینکه از نظر ما سونی WH-1000XM4 همچنان انتخاب بهتری است، ولی این هدفون هدفون نویز کنسلینگ به دلیل عملکرد تحسین برانگیز خود در حذف صدای مزاحم همچنان یکی از ببهترین هدفون های با قابلیت حذف صدای مزاحم موجود در بازار به شمار می‌آید.

Is Green Tea a Better Alternative to Black Tea?
Most of us have been smitten with black tea throughout our lives. There is something very special about this variety of tea which has gotten us hooked throughout the years. Most people do not know that all the different varieties of teas, i.e., black tea, green tea, oolong tea and white tea are made from the same Camellia sinesis plant which has a Chinese origin. Even though black tea is a favorite of many, slowly but surely green tea seems to be grabbing the spotlight. In the past decade, we have noticed a phenomenal jump in the sale of green tea. Now a lot of this has to be credited to marketing, but green tea does bring a lot to the plate, or should we say, palate, and is definitely worth the hype around it. If you don’t like black tea for some reason, or if you are unappealed by the caffeine kick that it provides with, then, it is time you switch to green tea leaves, as it is a better alternative with more health benefits to offer. Why Green Tea Now many people do not understand the difference between the black and the green brew and we are here to explain. Well, the fact of the matter is that both the brews are derived from the same plant, however, it is the processing which sets them apart. While black tea is fully fermented or oxidized, green tea is unfermented and does not undergo the stages of oxidation. This really helps the green brew in keeping all the health benefitting properties as well as antioxidants intact, making sure that this tea preserves the sanctity of all the nutrients it contains. Organic green tea is often referred to as the weight loss tea because it is a 0 calorie beverage when consumed by itself. However, you can add some lemon, honey and mint leaves into it, to enhance its flavors. What Makes Green Tea Better Than Black Tea? The fact of the matter remains that, believe it or not, agreen tea has a lot of health benefits which black tea doesn’t, as the processing deprives the leaves and rips it off all the nutrients which naturally possess. If you happen to be a black tea lover, then you will definitely realize that chai, made from milk, sugar and tea leaves does nothing to improve your overall well being. Therefore green tea has definitely proven to be an excellent alternative for health freaks and enthusiasts. In case you wish to include the green brew in your daily diet, then be sure to buy green tea online from Teafloor, to lay your hands on unadulterated, good quality green tea. You can bag the brew at an excellent green tea price.

Tips to secure your IOT based development solutions and services
The COVID-19 pandemic and 2020 lockdown put all analyst predictions into confusion, but as the economy begins to recover, IT consumption is predicted to pick up again, including the rise of the Internet of Things(IoT). The Internet of Things is not a single category, but rather a set of sectors and use cases. According to Research healthcare, smart offices, location systems, remote asset management, and emerging networking technology would boost IoT market growth in 2021. The Internet of Things (IoT) has a lot of advantages and risks. Supporters of technology and manufacturers of IoT devices promote the IoT services as an effort to better and simplify our everyday life by connecting billions of “smart” IoT devices  (such as Smart TVs, Smart Refrigerators, Smart Air-Conditioners, Smart Cameras, Smart Doorbells, Smart Police Surveillance & Traffic Systems, Smart Health & Performance Tracking Wearable, etc.) to the Internet. However, because of consumer privacy and data security issues with IoT Devices, IT Security Professionals believe it is unsafe and too dangerous. Secure Connection People benefit from stable cloud technology in a variety of ways, from encryption to other solutions. Other options are: Improving the security of your Internet gateway Before a device boots up, it performs a stable boot, which is a software device check. Keeping the cloud-based provider’s solutions up to date on a regular basis. To protect your private browsing data from possible attacks, use a protected VPN link. Building a Secure Network Access Control should be activated on your network so that only approved devices can connect. You should take the following steps: Build a firewall. Secure your authentication keys. Install the most up-to-date antivirus software to keep your network safe and secure. Here are some IoT security solutions for the most common IoT security issues: Secure the IoT Network To protect and secure the network linking computers to back-end networks on the internet, use standard endpoint security features such as antivirus, intrusion prevention, and control mechanisms. Authenticate the IoT Devices Introduce various user management features for a single IoT device and introduce secure authentication protocols such as two-factor authentication, digital signatures, and biometrics to enable users to authenticate IoT devices. Use IoT Data Encryption Encrypt data at rest and in transit from IoT devices and back-end networks using standard cryptographic algorithms and fully encrypted key lifecycle management procedures to enhance overall protection of user data and privacy and avoid IoT data breaches. Use IoT Security Analytics  Use IoT Security Analytics Tools that can detect IoT-specific threats and intrusions that standard network security solutions such as firewalls can’t detect. Use IoT API security methods Use IoT API Security methods to not only protect the privacy of data flow between IoT devices, back-end systems, and applications using recorded REST-based APIs, but also to ensure that only approved devices, developers, and apps communicate with APIs, as well as to identify possible threats and attacks against specific APIs. Test and IoT Hardware To ensure the security of IoT hardware, set up a robust testing process. This involves detailed testing of the range, power, and latency of the IoT system. Chip manufacturers for IoT devices must also improve processors for improved protection and lower power usage without rendering them too costly for consumers or too impractical to use in existing IoT devices, provided that the majority of IoT devices on the market today are inexpensive and disposable with minimal battery power. Develop Secured IoT Apps Given the immaturity of current IoT technology, IoT application developers must place an emphasis on the security aspect of their applications by integrating any of the above IoT security technologies. Before creating any IoT applications, developers must do complete research into the security of their applications and try to achieve the best possible compromise between the user interface and the security of their IoT software. Be Aware of the Most Recent IoT Security Threats and Breach Conclusion To ensure the security of the IoT devices and applications, the device makers and app developers must beware of the latest IoT security risk and breaches.  Since the Internet of Things is also a new concept, security flaws are likely to happen. As a result, all IoT device manufacturers and IoT app developers must be prepared for security risks and have a proper exit strategy to secure maximum data in case of a security attack or data breach  Finally, all IoT device manufacturers and IoT app developers must take action to inform their staff and customers about the current IoT risks, breaches, and security solutions.

Tone là gì? Cách xác định Tone giọng
Tone là gì? Cách xác định Tone giọng như thế nào? Để có thể cải thiện được giọng hát của bạn hãy cùng chúng tôi tham khảo chi tiết trong bài đọc này nhé! Tone là gì? “Tone” là một từ tiếng anh, dịch sang tiếng việt trong lĩnh vực âm nhạc có nghĩa là “giọng”. Có thể hiểu “tone nhạc” là giọng của bản nhạc. Vậy giọng của bản nhạc là gì? Người ta quy ước có 30 loại giọng khác nhau được xếp theo từng cặp giọng trưởng và giọng thứ song song, bao gồm: Đô Trưởng (C) và La thứ (Am) Sol Trưởng (G) và Mi thứ (Em) Rê Trưởng (D) và Si thứ (Bm) La Trưởng (A) và Fa (thăng) thứ (F#m) Mi Trưởng (E) và Đô (thăng) thứ (C#m) Si Trưởng (B) và Sol (thăng) thứ (G#m) Fa (thăng) trưởng (F#) và Rê (thăng) thứ (D#m) Đô (thăng) Trưởng (C#) và La (thăng) thứ (A#m) Fa Trưởng (F) và Rê thứ (Dm) Si (giáng) Trưởng (Bb) và Sol thứ (Gm) Mi (giáng) Trưởng (Eb) và Đô thứ (Cm) La (giáng) Trưởng (Ab) và Fa thứ (Fm) Rê (giáng) Trưởng (Db) và Si (giáng) thứ (Bbm) Sol (giáng) Trưởng (Gb) và Mi (giáng) thứ (Ebm) Đô (giáng) Trưởng (Cb) và La (giáng) thứ (Abm) Lưu ý: Thứ tự các dấu hóa xuất hiện trên khuông nhạc lần lượt là: + Thăng (#): Fa – Đô – Sol – Rê - La – Mi – Si + Giáng (b): Si – Mi – La – Rê – Sol – Đô - Fa Xem them: https://danamthanhhoitruong.com/cach-chinh-vang-co-hat-nhe/ Vậy làm sao để xác định tone của bài hát chính xác? Xác định tone giọng giúp đệm đàn hay hơn, đây cũng là cách giúp bạn xác định được những nốt chính trong toàn bộ bài hát. Bạn sẽ thực hiện bằng cách nhìn vào số dấu hóa của bài hát để xác định cặp giọng song song có thể là “tone” của bài hát. Ví dụ: Bản nhạc không có dấu hóa nào thì giọng của nó có thể là Đô Trường (C) hoặc La thứ (Am). Còn bản nhạc có 4 dấu giáng (b) thì giọng của nó có thể là La (giáng) Trưởng (Ab) hoặc Fa thứ (Fm). Tiếp theo để xác định giọng của bài hát chuẩn nhất, chúng ta sẽ cần chú ý tới một vài yếu tố sau: - Các dấu hóa bất thường xuất hiện trong bài hát. - Ô nhịp mở đầu (không tính nhịp lấy đà) và ô nhịp kết thúc của bản nhạc. Thông thường, các ô nhịp này chính là âm chủ của giọng trong bài hát. - Nếu bài hát đã có sẵn các hợp âm để đệm hát thì sẽ dễ xác định giọng hơn, vì trong hầu hết các trường hợp, tác phẩm đều được kết thúc bằng hợp âm chủ. Lưu ý: Để xác định được hai giọng Trưởng và thứ song song từ số dấu hóa có trên khuông nhạc một cách dễ dàng hơn bằng cách ghi nhớ quy luật sau đây: Nếu sau khóa nhạc có các dấu thăng, ta lấy dấu thăng cuối cùng tăng lên một bậc sẽ có giọng Trưởng, từ đó suy ra được giọng thứ song song.
