Feedforward Noise Cancellation: Anticipating and Canceling Noise
Unleash the Power of Proactive Noise Suppression
In the realm of noise-canceling technology, feedforward noise cancellation stands out as a trailblazing approach that anticipates and actively negates unwanted sounds before they reach your ears.
Feedforward noise cancellation is a sophisticated technology that employs external microphones strategically placed on the outside of the headphones or earbuds. These microphones continuously monitor the incoming noise, creating a “mirror image” of its sound waves. The headphones then generate an opposite sound wave that effectively cancels out the original noise before it enters the ear canal.
Principle of Feedforward Noise Cancellation
The principle behind feedforward noise cancellation is phase cancellation. When two sound waves with identical frequencies but opposite phases meet, they cancel each other out, resulting in silence. Feedforward noise cancellation capitalizes on this concept by creating a mirror image of the incoming noise and inverting its phase. When the inverted wave combines with the original noise, they nullify each other, leaving you with a serene and noise-free environment.
Advantages of Feedforward Noise Cancellation

Active noise cancellation (ANC): ANC uses a combination of feedforward and feedback microphones to cancel noise across a broader frequency range, including higher frequencies. However, it can be more power-hungry and bulkier.
-
Passive noise isolation: Passive noise isolation relies on physical barriers, such as eartips or cushions, to block out noise. It is effective at reducing low-frequency noise but less effective at higher frequencies.
-
Hybrid noise cancellation: Hybrid noise cancellation combines feedforward and feedback noise cancellation to achieve optimal noise reduction performance across a wide frequency range.
Feedback Noise Cancellation: A Deeper Dive into the Inner Workings
Feedback Noise Cancellation (FNC) is a sophisticated noise reduction technique that utilizes internal microphones placed within the ear cups or earbuds to detect and counteract unwanted noise.
Imagine this: as sound waves enter the ear cup, the internal microphones pick up the sound signature of the external noise. This information is then processed by the device’s circuitry, which generates an inverted version of the noise. This inverted waveform is then played back through the headphones’ speakers, effectively canceling out the original noise.
The key to FNC’s effectiveness lies in the tight timing and precise control of the inverted waveform. By perfectly matching the amplitude and phase of the original noise, the two waveforms interfere with each other, resulting in near-complete noise cancellation.
