Active noise cancellation on open-ear smart glasses

ArXi:2604.05519v1 Announce Type: cross Smart glasses are becoming an increasingly prevalent wearable platform, with audio as a key interaction modality. However, hearing in noisy environments remains challenging because smart glasses are equipped with open-ear speakers that do not seal the ear canal. Furthermore, the open-ear design is incompatible with conventional active noise cancellation (ANC) techniques, which rely on an error microinside or at the entrance of the ear canal to measure the residual sound heard after cancellation.
