Abstract: Disclosed herein are embodiments of a hearing aid adapted to be worn at an ear of a user including one or more microphones and a processor configured to apply one or more processing algorithms. The processor can include a feedback control system for estimating a feedback path. The processor can be configured to estimate a speaker unit size in dependence of an estimated feedback path, wherein the feedback path is estimated while said hearing aid is located in a specific position away from the user's head. A method of operating a hearing aid is further disclosed.
