The induction fields are generated by
electronics equipment, which are
pretty much silent but they do produce
heat at high power level. A soft-
sounding cooling fan run when the
unit is running multiple cooking
elements at high settings at once or
when a cooking element is set at very
high power settings.
What can sometimes produce sound
with induction cooking is not the
induction equipment but the cookware
itself. Slight sounds may be produced
by different types of cookware. Some
of the possible causes include:
Cookware with irregular or warped
bottoms can vibrate audibly on the
ceramic glass surface, though again
typically only at high power settings.
A “Cracking” noise may be heard if
the cookware base is made of layer of
different material.
A low “humming” noise occurs when
cooking, which is normal particularly
at high power settings.
Whistling can occur if both elements
are being used at the same time at
the high settings, and the cookware
has bases made of layer of different
material.
Loose-fitting handles on cookware,
typically when riveted on, can vibrate
slightly.
High quality cookware of solid cast
iron including enamelware will lower
the noise.
Operational Cooktop Noises
Heavier pans such as enameled cast
iron produce less noise than a
lighter weight multi-ply stainless
steel pan; Light weight cookware
may also vibrate. Heavy weight
quality cookware is recommended.
