Yes, I wondered what that was supposed to convey! I thought perhaps it was 90 times the sampling rate (96000 per sec), but that would be about 8mhz, which is not fast at all, or maybe it is for an ear bud?
- crazygringo 2y agoMy guess is it's the speed with which the microphone picks up a signal, the chip processes it, and updates the noise-canceling waveform on the speaker? So that's the time, and the distance is between microphone and speaker, so it can be compared to the speed of sound. No idea if that's plausible or even what they actually meant though.
- jayd16 2y agoPretty 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.
