The Thermomix ® works very quietly in almost all situations. As with all motorized kitchen appliances, the Thermomix® may get noisier for a short time when starting to chop hard foods such as grains, ice, or frozen fruits. The device produces a similar level of noise to a grain mill, but it reduces after just a few seconds.
If the Thermomix is to loud.
As using the Thermomix® to chop big pieces of vegetables, the device may start to vibrate and produce a loud noise. If that happens, consider cutting the vegetables into smaller pieces that may fit between the cutting knife of the device. Assure that the device lays stable on an even surface and that there is nothing under the device like a power cord.
Considering the finishing sound of the device that informs you that the step is finished, you may set up the volume of that sound in the device settings.
