Induction heating technology is based on the creation
of electromagnetic fields which enable heat to be
generated directly in the base of the pan. Depending
on the construction of the pan, these electromagnetic
fields may produce certain noises or vibrations as
detailed below:
This noise is produced when cooking with high power
levels. It is the quantity of energy transferred from the
cooking hob to the pan which causes the noise. This
noise will disappear or lessen as the power level is
reduced.
This noise is produced when the pan is empty. The
noise disappears as soon as food or water is added to
the pan.
This noise is produced by pans which are composed
of different superimposed materials. The noise is
caused by the vibration of the contact surfaces of the
various superimposed materials. This noise comes
from the cookware. The quantity of food and method
of cooking may vary.
This noise is mostly produced by pans which are
composed of different superimposed materials, as
soon as these are used at full heating power and at
the same time on two hotplates. This whistling
disappears or lessens as soon as the power is
reduced.
