This article delves into the world of noise cancellation, exploring its mechanics, benefits, limitations, and the ongoing debate surrounding “true” noise cancelling technology.
Understanding Noise Cancellation: The Basics
Noise cancelling technology primarily falls into two categories: passive noise cancellation and active noise cancellation (ANC).
Passive Noise Cancellation
Passive noise cancellation relies on the physical design of headphones to block out external sounds. Factors contributing to passive noise cancellation include:
- Material Quality: Thick padding or well-designed ear cups can create a seal around the ears, preventing ambient noise from entering.
- Fit and Design: Over-ear headphones tend to offer better passive noise isolation than on-ear or in-ear models.
Active Noise Cancellation
Active noise cancellation is where things get interesting. It uses technology to detect and counteract ambient sounds:
- Microphone Activation: ANC headphones have built-in microphones that pick up surrounding noises.
- Sound Wave Reversal: The headphones create sound waves that are the exact opposite (or inverted) of the external noise. When these waves interact, they cancel each other out, resulting in a quieter environment.
While ANC technology can be incredibly effective, it is important to recognize its limitations and the specific conditions under which it excels.

What are true noise cancelling headphones?
True noise cancelling headphones use advanced technology to reduce unwanted ambient sounds, allowing the listener to enjoy music or peace more effectively. They typically employ active noise cancellation (ANC) techniques that involve microphones detecting external sounds, which are then countered by creating sound waves that are the inverse of the detected noise. This technology is particularly effective for constant sounds like the hum of an airplane or air conditioning.
In addition to ANC, true noise cancelling headphones may also offer passive noise isolation, which physically blocks sound waves through the design and materials used in the ear cups. This combination of active and passive noise cancelling is what most people refer to as “true” noise cancelling. While many headphones claim to have noise-cancelling features, true performance can vary widely based on the technology implemented.
How do noise cancelling headphones work?
Noise cancelling headphones work primarily through two methods: active noise cancellation (ANC) and passive noise isolation. ANC technology employs built-in microphones to pick up external sounds.
