No, it’s the opposite actually, when it works. Sound is just a pressure wave traveling through air. By outputting a diametrically opposed sound wave, you’re zeroing out the pressure. Noise canceling, when it works, lessening the pressure hitting your ear. If it really want to learn more, just look up YouTube videos on destructive interference. The problem is that it isn’t always able to do that perfectly so it could situationally increase the decibels for very short times.
