1. A method for operating a hearing instrument having at least one acousto-electric first input transducer and an electro-acoustic output transducer, which comprises the steps of:
generating a first input signal via the at least one acousto-electric first input transducer from an ambient sound;
breaking down the first input signal and/or a first intermediate signal derived from the first input signal into a plurality of frequency bands;
generating an output signal from the first input signal, or from the first intermediate signal, by means of frequency-selective signal processing;
determining a relevant subset of frequency bands from the plurality of frequency bands such that, in each of the frequency bands of the relevant subset, an output sound generated from the output signal by the electro-acoustic output transducer makes a contribution that lies above a defined or desired threshold;
verifying an activation criterion for activation of a subalgorithm for the frequency-selective signal processing only in the frequency bands of the relevant subset with an aid of signal components of the first input signal, or of the first intermediate signal; and
applying the subalgorithm to the first input signal, or to the first intermediate signal, in dependence on the activation criterion.
