Abstract

A method for calibrating a structure-borne sound-sensitive acceleration sensor with the aid of at least one microphone. For this purpose, the acceleration sensor is situated in an intended position on the body of a user. Furthermore, at least one acceleration sensor signal and at least one microphone signal are detected, the at least one acceleration sensor signal and the at least one microphone signal being synchronized and having been caused by a vocalization of the user. A frequency analysis of the acceleration sensor signal and a frequency analysis of the microphone signal are carried out. A frequency-dependent correction function for correcting the transmission function of the acceleration sensor is ascertained on the basis of the frequency analyses of the acceleration sensor signal and the microphone signal.
