Many things working on electricity make noise. There are different reasons for the intensity and duration of noises.
In the machinery era, the noises were louder. As the modern world progressed, the comfort of humans was given priority due to the tough competition.
Induction cooktops are modern era cookware. It works on the principle of electromagnetism to cook food.
Induction in itself is a noiseless process as the electronic fields used to generate energy are silent.
However, while cooking on Induction, you may hear certain sounds like humming, buzzing, or even rattling of cookware.
Sometimes these noises can be shrill or unpleasant but they are completely harmless. These sounds are perfectly normal and you don’t have to worry about your induction cooktop or cookware.
Noise development does not cause any damage to either of them. Secondly, noises created by induction or cookware are not material defects.
Noises can come from different causes. It is either the cooktop making humming noises or buzzes or the cookware or the fan that is built into the cooktop.

Different Noises And Their Reasons
Let me quickly give you an overview of the types of noise you may hear when working with an induction cooktop
A low humming sound can be heard while operating on high powers. It is perfectly normal and the humming.
This is caused by the amount of energy that is transmitted from the appliance to the cookware.
The sound will go quiet or go away when the cookware heats up or when the power is turned down.
Another reason for a humming sound can be the fan which is embedded inside the induction hob and switches on to dissipate the heat generated during cooking.
The electronics of an induction cooktop require a controlled temperature in order to function with precision.
To control the temperature, the fan runs at various speeds according to the temperature detected.
The fan may continue to run even after the cooktop is switched off to control the detected high temperatures.
At some particular power levels, when using adjacent elements, pan noise may interact and produce a low whistle or intermediate humming.
There can be occasional very soft tick sounds when you’re using the induction cooktop.
This can occur as the power controllers cycle the elements on or off to keep the element power steady and stable.
A crackling or rattling sound can occur when cookware consisting of different materials is used.
The noise is caused by the vibrations in the joint faces between the different layers. It can change depending on the type and amount of food being cooked and the size of the cookware.
Lightweight vessels like stainless steel and multi-ply stainless steel tend to make more noise.
There is something called less than ideal cookware. It is not a defect but an induction-related phenomenon. In lower-quality clad cookware, there is a sandwich of different metals.
For example steel inside, steel outside, and aluminum in the middle.
If the middle layer is merely encapsulated and not welded within it, it can move about, however microscopically, and cause a buzzing noise.
In some of the cookware, the buzzing won’t happen, but in those with low-quality clad cookware, the high-frequency oscillations of inductions magnetic field can cause them. Usually, this happens when the power is high.
The noise is not very loud but can cause annoyance.
Loose-fitting handles of cookware when riveted on can vibrate slightly and so can lighter weight lids, especially in a high power setting
Pans with irregular bottoms can vibrate audibly on the glass surface. The noises sound like the buzzing of a bee.
Pans can make a variety of sounds when residual moisture or condensation gets trapped within the pan or on the bottom and boils off while in contact with a flat cooktop.
Condensation happens when water vapor comes in contact with a cold surface. The vapor is turned into water droplets.
How to Avoid the Noises When Using an Induction Cooktop
When the sounds get too loud, try different power settings or different cookware.
Try to lower the power level, as sometimes, higher power levels are susceptible to noises.
If the cookware covers a large surface area on the cooking element it is bound to produce lesser noise.
Try using heavier vessels of the same material to avoid the vibrations of the cookware.
Cast iron cookware does not produce noises.
Cookware of the same material can include cast iron and stainless steel and enameled cast iron and stainless steel( magnetic).
Use high-quality clad cookware which has been welded between the layers.
Choose good quality cookware with flat even bottoms for a good fit and to avoid noise.
Ensure that the lids, handles, and other pieces are well attached and fitted.
Ask for a demo before purchasing in the shop.
This way you can get an idea of whether the induction hob makes a noise that is bearable to you or works effortlessly without sound.
When using adjacent elements, turn up or down the power level setting of one or both the elements to avoid a low whistle sound or intermittent humming.
Vessels that completely cover the element ring area will create lesser noises.
The problem of condensation can be solved by switching on ventilation or extractor for a while just before cooking and leaving it on for 10-20 minutes after cooking.
How an Induction Cooktop Works?
Induction cooktops use magnetic induction technology to heat the cookware.
An alternating current is made to pass through a copper element embedded underneath the cooktop.
It creates a magnetic field. This magnetic field permeates the base of ferromagnetic cookware. It results in the generation of a resistive electric current inside the cookware.
The resistive electric current is also known as eddy currents. These currents generate heat and heat produced in this way cooks the food.
It is the other way round here. The source of heat is the cookware and not the cooktop.
There is a certain condition under which the induction process works. The cookware should be made of a material that is ferromagnetic and magnetically conductive.
Cast iron, iron, enameled or glazed iron, magnetic stainless steels materials work on induction.
Copper, aluminum, glass, and non-magnetic stainless steel will not work unless a converter plate is kept underneath between the cooktop and the cookware.
Copper and aluminum clad with iron or stainless steel can be used.
A method to check the compatibility of cookware on the induction is to place a magnet and if it sticks to the base of the cookware, it will work very well on induction.
Induction cooktops are favored by millions due to their excellent advantages including efficiency, less wastage, performance, safety, quick-cooking, and ease to clean and maintain.
With all these advantages, many consumers have experienced noises while cooking on an induction cooktop. Let us find out details about these noises.
Hope the article has helped you understand the possible noises that can be heard while cooking on induction.
Following the above tips, you can have less noisy cooking or even noiseless cooking to an extent on induction.
Rest assured that the noises are just a part of induction functioning and completely harmless.
You can even try playing music or tv while cooking to camouflage the noises.
