They are not effective for controlling occupational noise exposure.

Why is noise-cancelling so expensive?

It also may depend on expensive electronic circuitry to do the active cancelling involving multiple microphones housed nearby. That’s why it’s more expensive than your average headphones.

Unlike cell phones, noise-cancelling headphones do not emit low level radiation and do not pose any of the potential hazards that could stem from frequent use of a cell phone held next to the ear. Acute loud noises can damage hearing, interfere with sleep, raise blood pressure and stress levels and cause headaches.

How does Bose noise cancelling work?

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”.
