Pretty sure its this considering the next bullet says the same thing "Active Noise Cancellation with Silent Seal™ 2.0 adapts to your environment 3 million times per second and cancels up to twice as much noise." We're going to assume it means: - 90 calculations per the distance traveled from mic to speaker They also mention: - 3 million calculations/second Canceling out the calculation unit, that comes out to 33333 Mic-to-Speaker-Distances/second. We know: - Speed of sound is 343 m/s. That puts the Mic-to-Speaker-Distance at a bit over a centimeter.... that checks out.
