Abstract

The present invention relates to a method and a device for monitoring an exhaust-gas turbocharger of an internal combustion engine. In order to create an inexpensive and also reliably operating method and a corresponding device for monitoring an exhaust-gas turbocharger, it is proposed that a sound transducer which is designed to record rotational-speed dependent turbocharger operating noise is provided, which sound transducer is connected to an electronic system for frequency analysis for the output of a turbocharger rotational speed signal.
