The present invention relates to a method, which enables to identify the frequencies of the noises in the vehicles, essentially comprises the steps of collecting all sound together with the noise in the medium and recording to a digital medium, forming a spectrum graphic belonging to the collected sound data, viewing the said spectrum graphic, generating a sound in suitable amplitude in a suspicious frequency (S) to be selected from the spectrum graphic, and increasing only the amplitude of the sound in the said frequency, determining whether the sound in the frequency with increased amplitude (G) is the problematic noise. |
