Induction cooker whistles - why is that?

Induction cookers do not work quite silently. However, what meaning whistling sounds at the induction cooker, and what causes them, can be found in this post. What you can do to turn it off.

Normal noises at the induction hob

  • quiet hum
  • soft whirring
  • pops

These sounds are completely normal when operating an induction hob. They become louder the higher the cooking level is chosen. At low cooking levels, however, the sounds are barely perceptible to human ears (pets, however, they already hear, and occasionally the magnetic pulse, which is often a very unpleasant and disturbing noise for them).

Cause of the noise

The usual noises are caused by the functioning of an induction cooker. The building up magnetic field, which generates the heat in the pot, oscillates individual areas in the bottom of the pot at the molecular level. The occurring high-frequency vibrations are then made audible by the metal of the pot bottom.

Sound differences

There are also differences in the quality of the hob and the quality of the pots. The higher the two are, the lower the noise will usually be. They are then usually audible only in the highest cooking levels.


Whistling sounds do not belong to the usual noise in an induction hob. They may have the following causes:

  • There is an empty pot on the hob
  • The bottom of the pot is not completely flat (rare)
  • The bottom of the pot consists of several material layers with different properties

Remedy of whistling noises

The most important measure is to always fill pots with something when placed on the stove. Reducing the cooking level can also make the sounds quieter and disappear.

You can use pots with different materials in the floor area, but you should not use two such pots on adjacent hobs.

Tips & Tricks

Always make sure that the pot quality is as high as possible, always on clean, dry floors and that the pan bottoms are always completely level.
