Reply to comment by jswansong in Eli5 How exactly does Noise cancellation work? That too in such small airbuds by Professional-Ad3441
Excellent explanation.
Maybe worth adding that noise cancelling often gets mixed up with noise suppression.
Noise cancelling = actively reducing the noise by making the opposite sound (as described above)
Noise reduction = passively blocking the sound from getting in by plugging/covering your ear canal
