    From your source:

    While noise-canceling technology can effectively reduce the perception of external sounds, it does not necessarily eliminate the potential for hearing damage.

    In noise-canceling headphones, a microphone captures external sounds, and the internal speaker generates a counteracting sound wave that is 180 degrees out of phase. This process effectively nullifies the external sound at ear level. However, it is important to note that the sound pressure from external noise sources still exists even with active noise cancellation in place.

      Yes, but you said “seem quiet”. No. It actually cancels the sound waves. So if it’s quiet, it’s quiet. The pressure is a different problem.
