How Exactly Does ANC in Earbuds Work? 

Active Noise Cancelling (ANC) in earbuds, such as those offered by Srhythm, is a technology designed to reduce or eliminate ambient noise to provide a more immersive and uninterrupted listening experience. ANC operates through a combination of hardware and software components. Here’s a general overview of how ANC in earbuds works:

  • Microphones: ANC earbuds are equipped with external microphones, typically placed on the earbud’s outer shell. These microphones pick up the surrounding sounds, including background noise, conversations, and other environmental sounds.
  • Noise Analysis: The captured sound is then analyzed in real time by the earbuds’ internal processing unit. This analysis helps identify the frequency and amplitude characteristics of the incoming noise.
  • Anti-Phase Sound: ANC generates an “anti-phase” sound wave that is the exact opposite of the incoming noise. The goal is to produce sound waves that have the same frequency as the noise but with an inverted phase, meaning the peaks of one wave align with the troughs of the other. This is known as destructive interference.
  • Combining Sound Waves: The anti-phase sound is mixed with the incoming noise within the earbuds, and when they combine, they create a new sound wave. This new wave is designed to cancel out, or at least significantly reduce, the original noise.
  • Feedback Loop: The process doesn’t stop with a single analysis and generation of anti-phase sound. ANC systems continuously adapt to changes in the surrounding environment. They use feedback from the microphones to adjust the anti-phase sound wave as the noise profile changes.
  • Output to Ear: The resulting “anti-noise” is then fed into the earbuds’ speakers along with the audio you want to hear (music, podcasts, etc.). This allows you to listen to your content while the ANC system actively reduces or cancels out background noise.
  • Effective Noise Reduction: The combination of the anti-phase sound and your desired audio makes it seem like the background noise has been significantly reduced or eliminated, providing a quieter listening experience.

It’s important to note that while ANC can be highly effective at reducing continuous, low-frequency sounds like airplane engine noise or the hum of an air conditioner, it may not be as effective at canceling sudden, high-frequency sounds like a loud conversation or a door slamming. Additionally, the quality and effectiveness of ANC can vary between different brands and models of earbuds, including those from Srhythm, like Srhythm s5 Wireless Earbuds. The number and placement of microphones, the quality of noise analysis and processing, and the overall design of the earbuds can all impact the effectiveness of ANC.
