The system may be implemented as an advanced HPD in the form of an electro-acoustical earplug. The earplug comprises an OEMand an IEM. The system is configured to calculate an estimated IEM signal based on calculation of estimates of residual ambient noise, payback sounds or WID present in the ear canal.
