Summary:A capacitive sound transducer provided with a perforated attenuation disk. The invention further relates to a capacitive sound transducer and a condenser microphone having such a sound transducer. The sound transducer comprises a diaphragm and a counterelectrode which is disposed at a short distance from the diaphragm and provided with first perforations. In order to attenuate natural oscillations of the diaphragm at high frequencies, a capacitive sound transducer is proposed in which a sound-permeable attenuation disk provided with second perforations is disposed at a short distance from the diaphragm and opposite the counterelectrode. In this arrangement, the first perforations and the second perforations are also offset in relation to each other.
