A method for detecting changes in an area to be monitored of a conveying system utilizes a sound sensor and an evaluation unit connected to the sound sensor. The method includes emitting an acoustic pulse into the area to be monitored, recording an acoustic response signal of the pulse as an actual signal, determining an envelope of the actual signal, and detecting changes on the basis of the envelope.
