In a method for determining acoustic resonances in a magnetic resonance tomography system, a resonance measurement is implemented by applying a number of alternating gradient pulses that have a fixed time spacing relative to one another, applying an excitation pulse, and obtaining one or more MR signals, the MR signal of the resonance measurement is evaluated with respect to at least one parameter characterizing the acoustic resonance of the MRT system, the aforementioned steps are repeated with variation of the time spacing of the gradient pulses, a resonance curve is formed on the basis of the value of a characteristic parameter of the resonance measurement as function of the varied time spacing, and the resonance or resonances of the MRT system are determined from the resonance curve.
