IET Generation, Transmission & Distribution, 2023 The audible noise (AN) of HVDC transmission lines, as an external manifestation of the corona discharge, intensifies with the increase of altitude. In high‐altitude area, the AN has been a key factor in determining the type of conductors for transmission
