Modern fridge-freezers are relatively quiet, with noise levels around 35-45 dB. If noise is an important factor for you, look for models with low noise levels.
What are the advantages of the fridge-freezer?
Fridge-freezers are more ergonomic as the fridge, which is used most often, is at eye level. In addition, the fridge-freezers have a wide variety of models in width 60cm & 70cm and can be placed more easily in a small kitchen.
