The inductors can be clearly heard during operation. The "humming" but I would not call it annoying.
The fan is, in comparison to more expensive devices, also quite clearly heard, as a result of a high speed, with a relatively small fan diameter. From a (us) disturbing volume levels I can not tell here, however. There are just little restrictions which you should expect at this price.
An important aspect for us, is the ability to operate the hob to 220 volt.
This type of connection is provided by Thomson as one of several options so and is depicted in the accompanying description.
Our connection goes through two circuits, each with a 16 amp fuse (only one cable is 5 x 2.5 mm²), so that the two left areas on the one hand and the two right-hand zones are supplied via the second circuit. To follow all the four zones can be accessed at the same time also with 220 volts.
An important indication for the purchase I have to give:
Best leave a message to the seller of an ultimate phone number when ordering (although it is not asked at closing), for the recall of the forwarding to the agreement of the delivery date. It saves so expensive hotline calls and week long waits, because the goods are otherwise held indefinitely in stock.
One week after we had to purchase Thomson anmahnen where our delivery remains, only to find that they could not reach us in order to make an appointment for delivery, since you do not know our phone number.
Dear people of Thomson: That's a weak freestyle.
All in all, we are not quite satisfied with the device, with the purchase of Thomson-Hausgeräte.
