Noise-cancelling headphones are a type of headphone that use advanced technology to reduce or eliminate ambient noise in the surrounding environment. These headphones are designed to create a quieter listening experience by blocking out external sounds, such as traffic or background noise, and providing a more immersive listening experience.
Noise-cancelling headphones use one of two methods to block external noise: passive noise isolation or active noise cancellation. Passive noise isolation relies on physical barriers, such as ear cup padding, to block out external noise. In contrast, active noise cancellation uses microphones to detect ambient noise and generates a sound wave that cancels out the ambient noise before it reaches the listener’s ear.
The benefits of noise-cancelling headphones include reduced stress and improved concentration in noisy environments, improved audio quality due to the reduction of external noise, and the ability to listen to music or podcasts at a lower volume, which can be beneficial for hearing health.
However, the downsides of noise-cancelling headphones include their relatively high cost, the need for power (in the case of active noise cancellation), and the possibility of diminished sound quality for certain types of music. Additionally, some people may experience discomfort from wearing noise-cancelling headphones for an extended period of time.
