In a method for operating a hearing aid, an input signal is generated by way of one or more microphones. The input signal is amplified in an amplifier with an adjustable gain factor and output as an amplified input signal by way of a receiver. Furthermore, an OVD (own-voice-detection) parameter is established by an OVD unit. The OVD parameter specifies whether or not the user themselves is speaking. The gain factor is adjusted in a manner dependent on the OVD parameter and additionally adjusted in a manner dependent on noise, in particular stationary noise.
