The Science Behind ANC
Obviously, ANC stands for Active Noise Cancellation – a technology used in headphones to reduce ambient noise. But what exactly is the science behind ANC and how does it work?
Sound Waves and How They’re Cancelled
To understand ANC, we need to first understand how sound waves work. When a sound wave reaches your ear, it creates vibrations that are interpreted as sound. ANC works by using microphones to pick up these incoming sound waves and then producing an opposite sound wave to cancel them out. This process effectively eliminates the unwanted noise, leaving you with only the music or audio you want to hear.
Types of Noise Cancellation
There are two main types of noise cancellation: feedforward and feedback. Feedforward ANC uses microphones on the outside of the headphones to pick up external sound and generate the opposite sound wave, while feedback ANC uses microphones inside the ear cups to pick up the sound produced by the headphones themselves. Recognizing the differences between these types of ANC can help you determine which is better suited to your needs.

Key Components of ANC Headphones
Not all headphones are created equal, and when it comes to ANC (active noise cancellation) headphones, there are key components that make them stand out from the rest. Understanding these components can help you make an informed decision when purchasing ANC headphones.
Microphones: The Ears of the System
One of the most crucial components of ANC headphones are the microphones. These microphones act as the ears of the system, picking up external sounds and analyzing them to produce anti-noise signals. By strategically placing multiple microphones on the headphones, the system can effectively capture and cancel out a wide range of ambient noises, from low-frequency rumblings to higher-pitched sounds.
Digital Signal Processing (DSP): The Brain Behind ANC
Any ANC headphone worth its salt relies heavily on digital signal processing (DSP) to process the signals from the microphones and generate the anti-noise signals. The DSP is essentially the brain behind ANC, as it needs to be fast and accurate in its processing to effectively cancel out unwanted noises. This sophisticated technology allows ANC headphones to create a sound wave with the exact opposite amplitude of the incoming noise, effectively neutralizing it and providing a quieter listening experience.
Components like microphones and DSP play a crucial role in making ANC headphones stand out from regular headphones. Understanding how they work together can help you appreciate the technology behind ANC and make an informed decision when selecting the right ANC headphones for your needs.
