Extremely noisy

I bought this refrigerator a few months ago. The appearance is very beautiful, internally it is large and comfortable. The problem with this model is that it is extremely noisy: the manufacturer declares 45 db. I placed it in the kitchen, as a free installation. The noise is continuous, very annoying and very high. I am often forced to turn it off because of the discomfort. It is not possible, in my opinion, to use it for free installation. It is possible that in a piece of furniture the noises are muffled. A second problem is due to a buzzer that emits a short melody every time one of the doors is opened. After a few weeks it can become extremely annoying. I have sent an email to the producer to complain about these problems but I have not received an answer. Soon I will sell the refrigerator to buy a less noisy one.
