Yes. You may hear a buzzing or humming sound when a Cue burner is cooking. This is typical induction noise and it is normal. 

The noise tends to be more noticeable with an empty pan.  As a note, there are also noise differences between types of cookware: some are noisier than others. 

Additionally, the internal fans may turn off and on periodically even when the burner is off or not producing heat. This is normal and allows a Cue-enabled cooktop to cool itself during and after cooking.
