All About Noise Cancellation: Ai ANC, ANC and ENC Explained!!!

Noise cancellation technology has evolved significantly over the years, making it easier for consumers to find the best headphones suited to their needs. Let's dive deep into the journey of noise cancellation, its different types, and how modern advancements have revolutionized this technology.

What is Noise?

Noise is any unwanted sound that disturbs the clarity and quality of the desired audio. For example, if you're having a conversation and a dog barks suddenly, that barking sound is considered noise. Imagine you are speaking into a microphone, and there is an overlapping background disturbance; that disturbance is the noise we aim to eliminate.

History of Noise Cancellation

The inception of noise cancellation dates back to 1978. An engineer traveling from Zurich to Boston experienced a noisy flight which hindered his ability to listen to music peacefully. Frustrated, he began sketching designs on a napkin, which laid the foundation for modern noise-canceling technology.

Dr. Amar Bose, the mind behind this technology, developed the first Bose headphones that implemented environmental noise cancellation (ENC). These headphones used silicone or rubber to physically block external noise. Despite being effective, this method couldn't entirely drown out ambient noise.

Active Noise Cancellation (ANC)

The next significant advancement was the introduction of Active Noise Cancellation (ANC). ANC works by generating an equal but opposite sound wave that cancels out the unwanted noise. This real-time processing makes it highly effective, thus overcoming the limitations of ENC.

Ai-based Noise Cancellation (Ai ANC)

Further innovation led to Ai-based Noise Cancellation (Ai ANC). Modern processors with preloaded noise samples can now reduce noise in real-time. Notable examples include Samsung’s Voice Focus Mode and the Voice Enhancement Mode in iPhone 15. Adobe Podcast is another AI-based web tool that refines recorded audio to studio-quality levels.

Choosing the Best Headphones

Given the advancements in noise-canceling technologies, choosing the right headphones can be challenging. In my opinion, ANC-based headphones and earbuds are the best options. They offer substantial noise cancellation and are more cost-effective.

For those interested in Ai ANC technology, be prepared for a higher price tag and limited availability in the market. Popular options include Apple’s and Samsung’s mid-range devices. If you’re on a tight budget, Realme Airbuds provide excellent MC-based (Mechanical Cancellation) features at an affordable price.

In conclusion, technologies like ENC, ANC, and Ai ANC have come a long way, making noise cancellation more effective and accessible. Choose a model based on your budget, preferences, and noise-canceling needs.

FAQ

Q1: What is the difference between ENC and ANC? A1: ENC (Environmental Noise Cancellation) uses physical materials like silicone or rubber to block noise, whereas ANC (Active Noise Cancellation) generates an opposite sound wave to cancel out unwanted noise.

Q2: How does Ai ANC work? A2: Ai-based Noise Cancellation uses modern processors with preloaded noise samples to reduce noise in real-time.

Q3: Are Ai ANC headphones better than ANC headphones? A3: Ai ANC headphones can provide superior noise cancellation but are generally more expensive and less widely available than traditional ANC headphones.

Q4: What are some examples of Ai ANC technologies? A4: Examples include Samsung’s Voice Focus Mode, iPhone 15’s Voice Enhancement Mode, and Adobe Podcast’s audio refining tool.

Q5: What are cost-effective noise-canceling headphones? A5: ANC-based headphones from Apple, Samsung, and Realme Airbuds offer good noise cancellation at a more affordable price point.
