Abstract
A method for detecting squeaking noises within a sound signal generated during operation of a motor vehicle or during operation of a component thereof is described; in this method the sound signal is detected; an amplitude spectrum of the sound signal representing the amplitude distribution in a frequency range is generated at a minimum of two points in time and the existence of a squeaking noise is detected by analysis of the at least two amplitude spectra.
