Modern fridges are usually between 32 and 47 decibels. Anything below 40 is considered a “quiet" model and will be marketed as such. So 45 is perfectly within the normal/expected noise level.
The typical modern refrigerator runs at a noise level range of 32-47 dB (decibels). A unit that runs at lower than 40 dB is typically considered a quiet refrigerator.
The average commercial refrigerator operates between 45 dB and 75 decibels; most domestic fridges range from 32db to 47dB. The louder the refrigerator, the more disruptive it may be in a shared workplace or if it's in a quiet residential area.
20 dB: Whispering from five feet away. 30 dB: Whispering nearby. 40 dB: Quiet library sounds. 50 dB: Refrigerator.

The refrigerator is noisy when it starts running, and it is unavoidable. Small refrigerators (<250L) with a noise level below 39 decibels and large refrigerators with a noise level below 42 decibels meet the standard.
Noise levels should not exceed 45dB for a considerable amount of time.
50 decibels is a safe, quiet noise level comparable to the following common sounds: A quiet conversation. A quiet office or home. A quiet residential street.
A rattling sound can also be heard if the drain pan at the bottom is too loose. A mild humming sound coming from a fridge is normal because it is the sound of the compressor. However, if the sound becomes so loud that you can hear it from next door, your compressor needs to be repaired.
Absorption Fridges
It uses a source of heat, such as an electric heating element. Because there is no motor, they are a lot quieter than compressor fridges. These are often used in hotels, and if you need to run a fridge permanently in the same room as you sleep, an absorption fridge is strongly recommended.

In the world of sound measurement, 50 decibels (dB) is considered to be a moderate level of noise. It is equivalent to the sound of a quiet conversation at home or the humming of a refrigerator.
Any noise exceeding 70 dB is considered disturbing. Residential limits usually start at 60 or 55 dB (the equivalent noise of a regular vacuum cleaner).
