In order to check an occurrence of a signal component in an input signal, a method and a device is provided. The method comprises the steps of generating a measure for the frequency of the input signal from the input signal, determining a variance of the measure for the frequency of the input signal, comparing the determined variance with a predetermined limit value, and confirming the occurrence of the signal components if the variance lies within a predetermined range in relation to the predetermined limit value. The occurrence of a signal component in an input signal can be determined very fast and by performing only a few steps. Therefore, the method according to the invention and the device according to the invention can very well be used in particular in mobile devices, as for example in hearing devices.
