Noise Cancelling Headphones At Work

Noise cancelling headphones are useful for blocking out sounds in loud places like trains, buses, and public places. The noise cancelling headphones cancel the sound waves from the surrounding environment and distort the sound waves. The sound wave distortion can be compared to a person swimming upstream. If a river has a downstream current the same as your upstream strength, then you won’t move. In this scenario, the headphones stay silent!

Models of Noise Cancelling Headphones

Two models of noise cancelling headphones include the over the head headphones and the earbud headphones. The over the head headphones are bigger but the earbud headphones are more convenient.

There are also two types of noise cancelling headphones that are made to decrease the noise from the background. The two types are  passive and active. Passive headphones muffle the outside sounds to prevent the interference. Active headphones, however, electronically lessen outside sounds and create a quiet listening environment.

Passive Noise Cancelling Headphones

Passive headphones are made of a cup-like rim that surrounds the ear. The rim is made with highly dense foam and sound masking material. It is extremely soft and does not hurt your ears which creates a round seal that can block up to 20 decibels.

Active Noise Cancelling Headphones

Active noise cancelling headphones are more technologically up to date and have the ability to block 20 decibels more than the passive noise cancelling headphones.The key feature of the active noise cancelling headphones is its sound phasing technology. It uses a microphone to analyze the outside sound. The external noise is analyzed and a perfect reflection is made by the phase circuit.

Noise Cancelling Headphones Produce Anti-Noise

Headphone speakers play anti-noise along with your music. Artificially created anti-noise is the exact opposite of outside sounds that have gone into the device. When the two sounds meet, they both cancel out. The result is that the external noise dissipates and the music you are hearing becomes incredibly crisp and clear.
