How noise cancelling headphones work

Active Noise Cancellation (ANC) technology in headphones works by using microphones to pick up external sounds, which are then analyzed by an advanced chipset. The system creates an inverted sound wave to neutralize the incoming noise, effectively canceling it out before it reaches your ears.

This technology is designed to provide a quieter listening experience by actively reducing ambient sounds. For example, the Jabra Evolve2 75 headset features adjustable Jabra Advanced Active Noise Cancellation (ANC), allowing users to control how much of their surroundings they hear.

Noise-cancelling headphones are especially useful in noisy environments like public transport, as they help block out background noise, reducing the need to increase volume to unsafe levels. While noise-cancelling headphones are effective, it is still advisable to listen with headphones for no more than an hour at a time and take 15-minute breaks.

It is important to be aware that prolonged exposure to sounds over 85 decibels (dB) can be harmful to hearing. Listening to music through headphones at maximum volume, which can range from 100 to 110 dB, for extended periods can lead to significant hearing loss.

Dyson noise cancelling headphones

Dyson has entered the audio market with their unique take on noise-cancelling headphones, most notably the Dyson Zone and the Dyson OnTrac. These headphones combine Dyson's design principles with advanced audio technology.

The Dyson Zone headphones are particularly distinctive, featuring an attachable visor that delivers purified air. They utilize eight noise-cancelling microphones, custom EQ, and intelligent signal processing for clear sound. The ear cups are designed with micro-suede cushions for comfort. The battery life is up to 50 hours with audio and noise cancellation, and 4 hours when the air purification feature is active. The MyDyson app allows users to monitor air quality and tweak settings.

The Dyson OnTrac headphones also offer impressive sound and noise-cancelling properties. They feature a unique style with customizable outer caps and ear cushions available in various colors. The OnTrac headphones use eight noise-cancelling microphones to detect surrounding noise, offering up to 55 hours of audio with ANC. They combine passive noise cancellation with active noise cancellation to reduce unwanted noise. The MyDyson app provides audio modes, EQ settings, battery information, and sound exposure insights. While the sound quality is generally praised, some users find the physical controls finicky.

Both models aim to tackle noise and, in the case of the Zone, air pollution, providing a multi-purpose solution for urban environments. While they may have a higher price point and unique design quirks, they offer a combination of innovative features and strong audio performance.
