2-4 Noise Canceling Optimization
The shape of the human ear varies subtly from person to person.
When you wear In-The-Ear headphones, there may be a very slight gap between your ear canal and the headphones depending on
the shape of your ear. The size of the gap varies from individual to individual.
Air leaking through this gap affects the loudness of the noise reaching your ears through the gap and this also affects the noise
canceling efficiency.
Noise canceling optimization corrects individual differences in the noise canceling effect by electrically adjusting the size and
spectrum of the noise canceling signal, thereby ensuring the best noise canceling effect for each individual.
