Does noise-cancelling Protect from loud noises?

They are designed to give you a high fidelity listening experience while reducing lower frequency sounds, but they will not protect your hearing in really loud noisy environments. In fact, they could actually increase chances for hearing loss if used in a noisy environment dominated by high frequencies.

Can noise-cancelling headphones block all sound?

Noise-cancelling technology cannot completely isolate sound due to the air trapped between your audio device and eardrum. However, the air is important for you to be able to hear music. Suppose you were able to remove the trapped air, the net effect is silence, no matter what volume your music is on.2021-01-29

How do noise-cancelling headphones block out sound?

The technology, known as active noise-cancellation (ANC), works by using microphones to pick up low-frequency noise and neutralise it before it reaches the ear. The headset generates a sound that’s phase-inverted by 180 degrees to the unwanted noise, resulting in the two sounds cancelling each other out.2017-03-16

For speech blocking, active noise cancelling headphones rely mostly on passive sound isolation, not on their electronics. With current top-of-the-line noise cancelling headphones, you can expect between 15 and 25 dB noise reduction from 500 to 2000 Hz, which is substantial but not nearly enough to eliminate speech.2018-10-30
