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

It is worse before the pan goes on and also 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 burner fan may turn off and on periodically even when the burner is off or not producing heat. This is normal and allows the burner to cool itself during and after cooking.
