Understanding Noise Cancelling Headphones

Noise cancelling headphones are designed to suppress unwanted ambient sounds by utilizing active noise control. This sets them apart from passive headphones, which rely on techniques like soundproofing to reduce ambient noise, if at all.

The primary benefit of noise cancellation is the ability to listen to audio content without excessively raising the volume. In environments such as airplanes, noise-cancelling headphones significantly improve the signal-to-noise ratio, making it easier to hear important information such as safety announcements. Additionally, noise cancellation can help offset the impact of distracting activities, providing a more immersive listening experience.

To cancel out lower-frequency noise, noise-cancelling headphones employ active noise control (ANC). A microphone captures ambient sounds, while a small amplifier generates sound waves that are exactly out of phase with the undesired noise. When the noise wave's sound pressure is high, the cancelling wave's sound pressure is low (and vice versa). The opposing sound waves collide and effectively cancel each other out through destructive interference. Most consumer-grade noise-cancelling headsets generate the cancelling waveform in real-time using analog technology, while other active noise and vibration control products utilize real-time digital processing. Lightweight earphones have been found to achieve better noise reduction than normal headphones, with in-ear headphones proving more effective than outer-ear headphones.

It is important to note that noise cancellation primarily targets constant droning sounds like road noise, while being less effective against short, sharp sounds like voices or breaking glass. Additionally, it may not be as effective in eliminating higher-frequency noises such as spraying sounds. To maximize sound reduction across the frequency spectrum, noise-cancelling headphones often combine sound isolation techniques with ANC. Noise cancellation can also be utilized without sound isolation to enhance the audibility of desired sounds, such as voices. It's important to understand that noise cancellation requires active circuitry and is never passive, contrary to references of "passive noise cancellation," which actually refers to products featuring sound isolation.

Noise-cancelling headphones are headphones which suppress unwanted ambient sounds using active noise control. This is distinct from passive headphones which, if they reduce ambient sounds at all, use techniques such as soundproofing.

Noise cancellation makes it possible to listen to audio content without raising the volume excessively. In the aviation environment, noise-cancelling headphones increase the signal-to-noise ratio significantly more than passive noise attenuating headphones or no headphones, making hearing important information such as safety announcements easier. Noise-cancelling headphones can improve listening enough to completely offset the effect of a distracting concurrent activity.

To cancel the lower-frequency portions of the noise, noise-cancelling headphones use active noise control or ANC. A microphone captures the targeted ambient sounds, and a small amplifier generates sound waves that are exactly out of phase with the undesired sounds. When the sound pressure of the noise wave is high, the cancelling wave is low (and vice versa). The opposite sound waves collide and are eliminated or "cancelled" (destructive interference). Most noise-cancelling headsets in the consumer market generate the noise-cancelling waveform in real time with analogue technology. In contrast, other active noise and vibration control products use soft real-time digital processing. According to an experiment conducted to test how lightweight earphones reduced noise as compared to commercial headphones and earphones, lightweight headphones achieved better noise reduction than normal headphones. The experiment also supported that in-ear headphones worked better at reducing noise than outer-ear headphones.

Cancellation focuses on constant droning sounds like road noise and is less effective on short/sharp sounds like voices or breaking glass. It also is ineffective in eliminating higher frequency noises like the sound of spraying. Noise-cancelling headphones often combine sound isolation with ANC to maximize the sound reduction across the frequency spectrum. Noise cancellation can also be used without sound isolation to make wanted sounds (such as voices) easier to hear. Noise cancellation to eliminate ambient noise is never passive because of the circuitry required, so references to passive noise cancellation actually are referring to products featuring sound isolation.

To prevent higher-frequency noise from reaching the ear, most noise-cancelling headphones depend on sound isolation or soundproofing. Higher-frequency sound has a shorter wavelength, and cancelling this sound would require locating devices to detect and counteract it closer to the listener's eardrum than is currently technically feasible or would require digital algorithms that would complicate the headphone's electronics.

Noise-cancelling headphones specify the amount of noise they can cancel in terms of decibels. This number may be useful for comparing products but does not tell the whole story, as it does not specify noise reduction at various frequencies.
